I downloaded the D-link driver from the website and transferred it on usb to my computer. When running the install.sh file I encounter the error "bash: make: command not found". Since I do not have internet, I cannot download the build-essential package that contains make. What can I do?

14.04 - How to upgrade to Ubuntu 15.10?
Ubuntu 15.10 was released yesterday. What's the proper way to upgrade from Ubuntu 14.04?
VirtualBox unable to capture device (USB Hard Drive)
I'm facing some issues with my USB hard drive and VirtualBox. The problem is that it's detected in devices list and I activate the checkbox to capture the device but it's not captured by the guest system (Windows 7). The only way I made it work was adding a filter in virtual machine configuration and when the system starts the device is captured but I don't want this behaviour because when I unplug the device and then plug it again, the same problem occurs, it won't recognize it again until I restart the virtual machine.
Suggestions? Thanks in advance.
grub2 - How to modify GRUB boot menu?
The system am looking after has two hard drives of 80GB each, with about 8 partitions between them; primary and extended. It has Intel Pentium 4 and 2GB rams
The following software were installed in them as listed in the GRUB boot menu.
- GRUB4DOS 0.4.4 2009-06-20, Memory: 640K / 1014M, MemEnd: 0x48D2A
- Lnux Mint 11 Kalya (sdb6)
- Windows XP Professional SP3 (sda1)
- Linux Puppy 5.4.2 Precise (sda3/puppy5.4.2)
- Ubuntu 11.04 Natty Narwhal (sdb8)
- Linux-Puppy 5.2.5 Lucid (sda3/puppy525)
- Linux-Puppy 5.3.3 Slacko (sda3/puppyslacko5.3.3)
- Advanced Menu
Lacking knowledge of Linux decided to remove all partitions and keep only two primary partitions on each Drive. In result, the situation now is two drives with 80GB each.
- On one drive, all the 80GB are unallocated space and would like to keep it like that until I read through the vast contributions and have the hang of Linux distributions.
- On the other drive the 80GB are used for the MBR and two primary partitions, both NTFS filesystem, 70Gb for the root bootable with Windows XP preinstalled and the rest for the 2nd partition which is reserved for use as recovery.
The problem is, GRUB boot Menu did not reflect this change. It is still showing the same old list (the 7 items listed earlier at top) of bootable programs.
Reading an article by Dedoimedo I thought I might be able to find where GRUB was installed and manually remove the entries from the boot menu: But didn’t get to fully understand it.
I also thought I might find GRUB stage 2 files or directory in the root directory with Windows XP, so I made file search in Windows explorer but it returned zero result.
I appreciate any help toward answering the following;
- Is it possible to substitute GRUB with Windows own Bootloader and how to do that?
- How to find where GRUB’s stage 1 & 2 files are installed; what are files or directory names?
- How to change the list on GRUB’s boot menu, if I have to retain GRUB?
- I understand that GRUB’s stage 1 could be found in the first sector installed alongside the MBR but how to find it?
I have Linux Mint 16 Live, System rescue.iso and GParted live.iso (which I used to delete the partitions): all of them are on CD’s.
There were lots of useful command strings in Dedoimedo’s article including complete command listing on how to add OS to GRUB menu. I thought removing programs from the menu would just be the reverse of adding a program: The problem is I was not able to do the first step of changing the command cursor / line from Mint $ character to GRUB directory.
Your help much appreciated

system installation - Will Ubuntu work on a Dell Inspiron 15R?
I want to know how to install Ubuntu on a Dell Inspiron 15R with Intel Core i3, 3GB RAM, Intel HD graphics and 320GB HDD. I've heard some people have had issues with the wireless card. Also, I tried a few days ago to install the 64-bit version of Ubuntu 10.10 and the installaten hung on the "Who are you" screen... Can anyone help me, I really want to get into Linux but without having any problems with the laptops drivers.
apt - Full changelog of updated packages for Ubuntu releases?
So for any given version e.g. 12.04, 12.10, 13.04,etc. a full changelog of all update packages e.g. MySQL, Apache, etc.?
Note: Raring Ringtail release notes says:
For a list of all packages being accepted for 13.04 Raring Ringtail, please subscribe to raring-changes.
The raring changes is a mailing list of nightmare proportions. Maybe there's a final, proofed, easy to understand, changelog of all updated packages?
You can find all changelog on http://changelogs.ubuntu.com/, but it's difficult to see.
So the best strategy is to go to http://packages.ubuntu.com, search for interesting packages, and on right column click on "Ubuntu Changelog".
wireless - Why is Wifi not working on my HP laptop?
The wireless card is not working but the Internet is working good with Ethernet cable.
The output of lspci is :
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
At fist the card was working but sometimes it's disconnected, and have problem on coverage range, and sometimes it's not working at all
I tried many solutions on the Internet but now it's not working at all.
I don't know what to do :(
backup - How to make a disk image and restore from it later?
I'm a new Linux user. I've reinstalled my Wubi from scratch at least ten times the last few weeks because while getting the system up and running (drivers, resolution, etc.) I've broken something (X, grub, unknowns) and I can't get it back to work. Especially for a newbie like me, it's easier (and much faster) to just reinstall the whole shebang than try to troubleshoot several layers of failed "fixing" attempts.
Coming from Windows, I expect that there is some "disk image" utility that I can run to make a snapshot of my Linux install (and of the boot partition!!) before I meddle with stuff. Then, after I've foobar'ed my machine, I would somehow restore my machine back to that working snapshot.
What's the Linux equivalent of Windows disk imagers like Acronis True Image or Norton Ghost?
Note: I found a similar question: Easy backup/restore of installed system?
drivers - Why won't my graphics work in Ubuntu 12.04 LTS?
I'm very new to Ubuntu and to Linux in general, and took the leap and formatted my PC to Ubuntu 12.04 LTS very recently :)
I seem to be having some trouble getting my graphics card to run properly, I looked over what information I could find but I still cannot get it up and running and figured this was a good place to ask for help.
The information I can find on my graphics is as follows:
lspci outputs:
01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880M [Mobility Radeon HD 4225/4250]
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Madison [Mobility Radeon HD 5650/5750 / 6530M/6550M]
I tried using a mixture of the following links:
How do I fix my installation of ATI Catalyst Video Driver in 12.04 LTS?
What is the correct way to install proprietary ATI Catalyst Video Drivers (fglrx) directly from AMD?
Ubuntu Precise Installation Guide
But it does not seem to work, since running fglrxinfo in terminal gives:
display: :0.0
screen: 0
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 1.4 (2.1 Mesa 9.0.3)
What am I doing wrong here?
All help appreciated.
Edit:
I have tried the legacy driver from http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip
I also tried the guide at https://launchpad.net/~makson96/+archive/fglrx which caused the system to crash (blackscreen, no boot)
Neither seemed to work. I did however reinstall ubuntu 12.04 LTS, and re-tried both with no success.
Reinstalling ubuntu did however fix the broken dependencies problems, etc.

windows - Access secondary hard disk from Virtual Machine
I have a fairly specific question.
I had Ubuntu on my Laptop (for years). For a variety of reasons, I've had to switch to Windows but the computer has two hard drives. The main drive was reformatted and I've installed windows. The second hard drive still has the Linux system disk format (not sure on type). Obviously, windows can't access it but can I access it from a Virtual machine (VirtualBox) or will I need to load up a Live-Session to access / move the contents?
Edit: If this is possible, how would one proceed to mount the disk?
In all honesty, I do not think so.
The reason for this:
Disclaimer: I loooove deductive reasoning. Brace yourself.
Let's look at out information, shall we:
- You have 2 hard drives. One of them has windows installed, the other uses a (currently) unknown linux filesystem.
- You want to create a Virtual machine. To do so, you need special software known as a Virtual Machine Hypervizor. An example of such software is VirtualBox.
- Windows is unable to use the hard drive at its current format.
- To create a virtual machine, you need to create a file that will act as a virtual hard drive. That file has to be stored somewhere.
- Since windows can not access the hard drive as is, it is highly unlikely it can use it to provide services to software running on it, like a Hypervizor (e.g Storage)
- So, the virtual machine will have to be stored on the hard drive that windows is installed on. =(
- Unless you get very technical in virtual machines or are a highly skilled computer hacker, there is (very very ...) little chance that you can access the host (physical computer) from the guest (virtual machine)
TL:DR: Theoretically anything that contains a virtual machine is highly unlikely to help.
However, you might be able to use partitioning software to format the hard drive and make it available to Windows.
networking - Realtek ethernet driver error ubuntu 16.04
I have recently upgraded from Ubuntu 15.10 to 16.04. when i was using 15.10 ethernet works flawlessly. But after upgrading to 16.04 it doesn't work anymore showing network cable unplugged. I tried reinstalling driver & end up getting following error
sumit@Lenovo-Z50-70:~/Desktop/r8168-8.041.01$ sudo ./autorun.sh
[sudo] password for sumit:
Check old driver and unload it.
rmmod r8169
Build the module and install
make[2]: *** No rule to make target 'kernel/drivers/net/ethernet/realtek'. Stop.
make[1]: *** [install] Error 2
make: *** [install] Error 2
When i had installed in 15.10 it was installed successfully.
My ethernet controller is: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev10).
I have done all proxy settings same as they were in 15.10.
Please help. :(
Get an internet connection(i got through wifi). Use the command:
sudo apt-get install r8168-dkms
Enter your password. This will install the latest version of the driver. Ethernet connection should be established after installing (you may reboot & check again).

wubi - Can I upgrade my ubuntu version and change to be primary OS after originally installing with Wibu?
I have recently installed Ubuntu 12.04 using Wubi 12.04 and I now wish to upgrade to a full installation of Ubuntu 14.04, Before attempting to upgrade through the update center I did some research on upgrading from a Wubi installation (alongside windows) to a full installation making Ubuntu primary and only OS and found that it is in fact doable through the update center however it is just highly recommended to perform a full backup before doing so. I have now finished backing up all the data I need to worry about and began the upgrade process through the update center and received the following error:
Your graphics hardware may not be fully supported in Ubuntu 14.04.
Running the 'unity' desktop environment is not fully supported by your graphics hardware. You will maybe end up in a very slow environment after the upgrade. Our advice is to keep the LTS version for now. For more information see https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D Do you still want to continue with the upgrade?
My questions are as follows: A. Isnt 14.04 a LTS version??? B, What are your recomendations in order to ensure my graphics driver is installed correctly and im not stuck with bad configs/install?
When it comes to the error it is saying that 14.04, although an lts release, does not have unity2d as you are probably using on your current computer with 12.04, and would have to try and run a full unity3d environment with software acceleration instead of hardware. What are your computer's specs? Also to make it a primary installation you can download boot-repair (google it for instructions on doing so) and elect to install it in the mbr of your drive, then update grub. It will most likely have ubuntu as the default boot option and may even have an option to boot windows below it. If you want to just use ubuntu after that, just delete the windows partition (after backing up everything you want to save) then run sudo update-grub /dev/sd then resize the ubuntu partition(s) CAREFULLY with gparted to take up the full disk.

empty jockey install proprietory nvidia after bumblebee on 13.04
I am trying to install the proprietory Nvidia drivers on my Asus UX32VD (GT620M) running 13.04.
Since the additional drivers (Jockey) tab was empty I followed the advice from a similar question here to install Bumblebee. Unfortunately the Jockey tab is still empty (as in, my card does not show up).
My question is twofold
- how do I get the Nvidia drivers to show up in the additional drivers tab?
- after having installed Bumblebee, which is the way to install Nvidia drivers? (as the Bumblebee site mentions something on specific packages)

How can I fix this problem?
Compiz has broken after installing 12.10 with ATI Catalyst 12.10 drivers
After upgrading to Quantal yesterday I installed the new ATI Catalyst drivers, the 12.10 version, for my ATI Radeon HD 7850 card. Upon logging into Ubuntu I am presented with no Unity. I can access terminal with Ctrl + Alt + T.
I tried uninstalling the driver, but that did not fix Compiz.
Does anyone know how I can fix Compiz? Any info on getting drivers working would be good too.
Edit: I solved this problem by first uninstalling the proprietary driver through the terminal, which I believe is in /usr/share/ati/amd-uninstall.sh. Then I rebooted and installed the open source driver, radeon, and rebooted again. It's slower than the proprietary drivers but it works.
Hi I have the answere for all of you, the problem is 12.10 doesn't include the kernel headers for some reason. so when installing drivers run sudo apt-get install linux-headers-$(uname -r) you can do this before or after it doesn't mater. Once thats done reboot your system and enjoy!

apt - How to install programs into user directory without sudo
I mean how to install programs from repos into the user directory without sudo?
There are two ways (and even more) of installing software: from repos and from the software developer's website (tarball). First method requires one to have the superuser password. One must use sudo to perform a command like this apt-get install app_name. The second method is to download a tarball from the website, extract it, place the extracted files into the specified directory (or build it first), set up shortcuts. As you can see, the second method needs a user to have certain skills, but the first one needs only a knowledge of the superuser password.
The question is — how to combine these advantages: not to know the password (install software to home directory), not to be skilled (install in one click) and to use software only from repos.
Why it looks not so complicated for me: as an example let's look at SweetHome3D. This app is available both in repos and on the developer's website. When I download the tarball I just extract it, rename the folder to make it invisible and set up the shortcut (make it and then place it into ~/.local/share/applications). Or I can just do $ sudo apt-get install sweethome3d
Now let's try something different (not necessary like this):
Perform $ apt-get download sweethome3d. This command downloads .dep file.
Extract the contents. There are no difficulties of doing this.
… (here are some automatic actions to make the app prepared to launch)
PROFIT!
Any ideas?
The deb file that is downloaded and installed when you run apt-get install is basically a build of the source code with most options already set. This includes the location where it would be installed, probably /usr/some_folder.
This means you cannot change this location by using a deb file. The only way to do this is to get the source code, modify it and then install it.

apt - Unable to locate package python-pip on live system
I am trying to install electrum on my Ubuntu live USB. Please forgive me because I am very new to this OS. I have also made a persistence 4GB space for installing software.
How can I get past this error? I tried using
sudo apt-get update
first, but I still get
E: Unable to locate package python-pip
when I try to install.
Two Methods:
You can install through Ubuntu Software Center.
Open Ubuntu Software Center and search for
easy_install
Highlight alternative Python package installer (python-pip) from the
list and click Install
You can check weather the installation was successful or not by
giving the commandwhich pipyou will see the path of installed application, for example
/usr/local/bin/pip
Second method
Open terminal by pressing CTRL+ALT+T and type the following:
cd ~to navigate to your home directory.
Then issue the below command:
wget -P Downloads/ https://svn.apache.org/repos/asf/oodt/tools/oodtsite.publisher/trunk/distribute_setup.pyNext step is to run the downloaded script. To do this, issue this
command:sudo python Downloads/distribute_setup.pyand type your user password when prompted (Please, note that your
account needs to be a member of Administrators group in order to
issuesudo).Hit
Enterand let the script run.To ensure easy_install is installed, issue the command below:
which easy_installThe typical response in case the installation completed successfully
would look something like this:/usr/local/bin/easy_installThe next thing to do is use easy_install to install pip. For that
you’ll need to issue:sudo easy_install pipEnter your password if prompted to confirm command.
Let the installer run and once the installation is completed type:
which pipThis command should typically respond with something like this:
/usr/local/bin/pip

I'm going to install ubuntu on sda4; currently my boot process is controlled by systemd-boot which is installed in archlinux via bootctl software. It's fine and I'd like to keep it.
By installing Ubuntu it will try to install grub on sda or sdaX. Look at the dropdown menu at this screenshot:
I want to install Ubuntu on sda4 without dealing with grub. Then I will point to Ubuntu vmlinuz file and initrd file by creating a new entry file in archlinux under systemd-boot configuration system.
12.10 - Is it feasible to install and play games in steam while steam is in Wine (PlayOnLinux)
So I downloaded steam on PlayOnLinux and I installed some random games and they open but I can't do anything with them I can move the mouse around and the menu buttons change, but I can't actually click anything. The games I tried it on were Castle Crashers, Deus Ex: HR, and Super Meat Boy and they all did the same thing. Should I just download the games from PlayOnLinux and then choose to download the steam version or can I actually have them in Steam, and I'm just doing something wrong. Also I'm on Ubuntu 12.10 using PlayOnLinux 4.19 with a GTX 560 and the NVIDIA Experimental Binary Drivers.
I use native Steam on Ubuntu for the games that are available for Linux, but I want to be able to play my other games that aren't available on Linux, and have them all in steam, instead of having them strewn around in PlayOnLinux.
installing ubuntu and starting windows isn't in boot option
I didn't installing ubuntu alongside my windows7.
I have windows7 installed in my ssd and ubuntu in another.
Right before I install ubuntu, I unplugged all my other hdd. 1st because it the ubuntu installation somehow didn't detect the hdd I want to install onto and 2nd because in that way I would be I didn't choose the wrong hdd to install ubuntu onto.
After ubuntu install is completed and running, I plugged my windows7 hdd and other storage hdd back.
But somehow when I restart my pc, it didn't even ask which os to use it just directly goes into ubuntu. I used F12 to have the option to select device to boot up with and I can clearly see my windows7 ssh and of course by clicking it, windows7 boots up properly.
I went into my bios and check my boot priority and options. There are only two boot options and the first is my ubuntu hdd and second is my optic drive. When I try to change the boot option, those two are the only options I can choose from. I cannot choose from any other hdd.
Can someone give me a hand?
Not sure if this is the place to post my question but this happened after ubuntu installation.
Thanks in advance people.
If you are looking for grub loader, please enter the following command in ubuntu-
sudo update-grub
After executing the above commands, reboot and check if the grub loader appears.
I had faced similar issue where I did not get the option to install ubuntu alongside windows and Ubuntu was loaded automatically. After executing the above mentioned command, I got the grub loader where I could choose the OS to load.
Hope that helps.
repository - What is "deb deb-src stable/xenial main" in /etc/apt/sources.list
I was going through Repository files and in file /etc/apt/sources.list, saw these lines :
deb http://ppa.launchpad.net/elementary-os/stable/ubuntu xenial main
deb-src http://ppa.launchpad.net/elementary-os/stable/ubuntu xenial main
Wherein, I understand that
http://ppa.launchpad.net/elementary-os/stable/ubuntu
is where apt-get would retrieve files from, but I couldn't get what the rest of words in it mean. These words are deb, deb-src, xenial main, stable main, trusty main.
Edit: Also, I found these lines while visiting this site and noticed [arch=amd64] in between deb and the URL.
echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" > /etc/apt/sources.list.d/chrome.list
So, The Question here is:
What do these words in
sources.listfile mean?deb
deb-src
xenial main
stable main
trusty mainAlso, What does
[arch=amd64]mean?
Your question revolves around the syntax or format of source list file that describes other programs what, how & from where to get the sources. So, Here it goes :
Apt ( Advanced package tool )
used to manage the repository on Debian & Debian-based (Ubuntu) systems. It uses a file that lists the Repository Sources from where packages should and can be obtained. Also the file lists how the packages should be obtained and from what subpackages (or suites).
The format in which entities are written tells everything to apt. However, there are two variations of the format.
- They have extensions
.list - Traditional format, supported by
all version of apt. - A single line entry describes the source.
Example :
deb http://security.debian.org stretch/updates main contrib non-free
- They have extensions
- They have extension
.sources - Supported by apt itself
since version 1.1 - Individual entries are separated by an empty line where each entry contains information in the form of
fieldname : value. Example :
Types: deb
URIs: http://deb.debian.org/debian
Suites: stretch
Components: main contrib non-free
- They have extension
As you can get an idea from deb822-style format what are those words you asked in question. Let's get into more details into the format.
1. Archive Type
- It tells which source is going to be accessed.
- The first word on each line possibly
debordeb-src, indicates the type of archive. debindicates that archive contains binary packages (deb), the pre-compiled packages that we normally use.deb-srcindicates source packages, which are the original program sources plus theDebian control files (.dsc)and the diff.gz containing the changes needed for packaging the program.- Format, syntax and names of the options vary between one-line-style and deb822-style formats as described above, but they both have the same options available.
2. Repository URL or URI Specification
Its simply a URL/URI to the source repository from where you want to get the packages. You can specify type for the URL/URI that can be anyone from the currently recognized URIs that are :
http | https | file | cdrom | ftp | copy | rsh,ssh
You can add more recognizable URI types, If you want.
3. Suite
A suite refers to combination of two attributes of distribution that are :
Release Code Name
An alias given to every release of OS. Every OS has got a Code Name
& you already now that How to get distribution's full code name ?Release Class
Defines the development phase of a package that can be one or the combination of the following :
stable testing unstable
4. Components
Components tell that whether package is :
- Free (As defined in context of free software) or Non-Free,
- Independent ( as in
main) or have dependencies somewhere else ( as incontrib). - whether they comply with DFSG or not.
- Also tell the Repository Sections that can be
mainorrestrictedoruniverseormultiverse.
5. Options
The EDIT part in your question refers to what is called as options. And as the name says, they are optional but when used, they modify the source entry to fetch a particular kind of packages. They can define :
Architecture for which packages are to be fetched. As in options in the source entry you quote in Edit part :
"[arch=amd64]"specific Language
- Trust level of sources
- Pdiff values
- and many others.
The Syntax (Revised) :
One-line-style format
[archive-type] [ option1=value1,option2=value2 ] URI suite [component1] [component2] [...]deb822-style format
Types: deb deb-src
URIs: uri
Suites: suite
Components: [component1] [component2] [...]
option1: value1
option2: value2

grub2 - Unable to boot into Windows 8.1 after installing on separate partition (not preinstalled)
I have decided to give Ubuntu a try, so I decided to install it alongside my Windows 8.1 (not preinstalled - It was delivered with Win7), though I had to make a custom install (had the "no system detected" or something upon installation). So I installed Ubuntu on a separate partition.
Anyways, when I booted up after installation, the PC booted directly up into Ubuntu, so I downloaded the Boot-Repair tool and ran it. When I boot up now, I reach the GRUB menu with Ubuntu as the only entries. Boot-Repair gave me this log.
How do I correctly add my Windows 8.1 to GRUB? I have just a little experience with Ubuntu (and Linux systems in general), so I am not sure what to do.
Thank you in advance!
networking - Network disabled - device not ready 16.04
Laptop: Acer V 13
no preinstalled OS. Freshly installed ubuntu 16.04.
At the top right corner, when I click the network manager, no wifi networks are found, and there's a grayed out device not ready text instead.
Ethernet cable is working (this is how I'm posting this ...)
I'm in a co working space with many networks and users so I know the problem is on my end.
Below you will find everything I've tried followed by every piece of information I thought might b relevant.
I also logged the result of this script which has some additional info, and tailed syslog for a while.
Thanks in advance, you rock! :)
Things I've tried:
$ sudo service network-manager start
(No output)$ sudo service network-manager stop && sudo service network-manager start
No output, network icon dissapears and reappears from tray$ sudo ifup lo
ifup: interface lo already configured$ sudo ifup enp2s0
Unknown interface enp2s0- using wicd network manager
I didn't detect any wireless network as well.
(I'm actually glad it didn't work, seems like a bad idea anyway) $ sudo service networking restart$ sudo service NetworkManager restart$ sudo echo "blacklist ath10k_pci" >> /etc/modprobe.d/blacklist.conf
after rebooting, any reference to wifi was gone from the network manager menu in the tray$ sudo apt-get install bcmwl-kernel-source

I don't know why it worked, here's what I did:
Backed up /lib/firmware/ath10k/QCA6174
Replaced it with https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174
Rebooted
At this point wifi was completely gone from the network manager menu.
so I restored the original QCA6174 folder, rebooted, and it works now!
Marking as solved.
If anyone knows why this worked I'm very curious ...

partitioning - Recover files from Damaged Partitiohn
I was using Ubuntu 10.10 with VirtualBox for my virtual machines. I think my hdd has some bad sectors because after one reset Ubuntu failed to start. After running fsck -y from live CD some changes were made to my partition. I tried to run testdisk from another PC to this harddrive but I can't access the old Linux partition. It appears deleted partition after deep scan. How can I recover my ova files? Testdisk also gives me a warning about number of heads/cylinder mismatches.
Try "R-Linux", it might recover your data and it's got nice GUI:
http://www.r-tt.com/free_linux_recovery/Download.shtml
There's probably also a way to repair broken partition, but I would recover data to another partition with R-Linux first (just in case).
After doing that backup, run DOS tool "HDAT2" from boot disc (like Hiren's Boot CD) and see if those were really bad sectors (it might even fix them for you - but don't count that drive will not fail again).
usb - how to get a DisplayLink display adapter working in Ubuntu 13.10
I have a UGA-2K-A USB 2.0 to DVI DisplayLink graphics adapter and I'm trying to get it to work on Ubuntu 13.10 in order to hook it up to a display.
First, I confirmed that the package xserver-xorg-video-modesetting was installed. It was by default.
Next, I connected the graphics adapter. The dmesg output on initial connection connection was as follows:
[ 4679.672775] usb 2-2: new high-speed USB device number 9 using xhci_hcd

[ 4680.330503] usbcore: registered new interface driver udl
I understand that the line
udl 2-2:1.0: fb1: udldrmfb frame buffer device
implies that the kernel driver has bound.
At this point, the LED on the device was not lit and the display connected to the graphics adapter did not register a signal.
Some information on the kernel and xrandr is the following:
uname -r

I rebooted the computer with the graphics adapter attached. The relevant dmesg output on boot was as follows:
[ 2.118884] usb 2-2: new high-speed USB device number 3 using xhci_hcd

[ 2.491175] usb 2-5: new full-speed USB device number 5 using xhci_hcd
At this point, the LED on the device is lit and the display connected to the graphics adapter registers a signal (though the image is black).
The output of xrandr --listproviders remains the following:
Providers: number : 1
Provider 0: id: 0x49 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel
I am not sure what to do next. According to a forum post, it may be that I need to slave the second graphics device to the first, but I have no idea how to do this. I would really appreciate some guidance. :) Thanks!
While the framerate is a little sluggish at times and there can be misidentifications of the the display dimensions occasionally, it is working in Ubuntu 14.04, so upgrading is one solution.
partitioning - How do I install Ubuntu on the C Drive without losing any data from the other drives?
This is the first time I am installing Linux.
I have Windows 7 on my C drive. I want to just format the C drive and then install Linux on the C drive only. So how can I install it on only the one drive (partition) replacing Windows 7?
When installing it is using the complete hard disk space.
grub2 - how to add windows 8 entry to grub after boot-repair
I installed ubuntu 14.04 in a dual boot (with windows 8.1) but my pc directly boots into ubuntu. For that I did a boot-repair->recommended repair. But all I got was grub menu with an option to boot to ubuntu.
here is the ubuntu pastebin file I got at the end of boot-repair:
http://paste.ubuntu.com/8433985/
It seems to identify the windows 8 partition, but I don't know how to add an entry for the same in the grub menu.
I searched the net but I couldn't understand the procedure (I am a newbie..)
So pl help me guys..
Thanx in advance..

I done everything what told on http://www.dickscheid.net/2011/10/19-cuda-ubuntu-1110/ and http://blog.ryant.org/2011/12/installing-cuda-toolkit-on-ubuntu-1110.html
then i reboot
now i see only title "Ubuntu" and ~5 points
I cant even switch to console (ctrl alt f 1-6)
anybody know what i can to do to save my ubuntu?
system installation - how can I install Ubuntu on my old computer
I've been trying to download and install Ubuntu on my Dell Inspiron 6000 laptop computer with no luck.
It's an old computer about 9 years old.
It has intel 1.6g processor and 2 gigs of memory.
I had tried to install one of the Ubuntu but I got a message that says I need an x86-64.
I have a 32bit laptop.
I have only one hard drive with windows XP on it,
How can I purchase a Ubuntu O.S. or download the correct Ubuntu for my particular computer but a current system where I can get support.
64 bit - is x86_64 a x86 or x64?
my ubuntu version is 12.04, and when cat /proc/version, it shows
Linux version 3.2.0-23-generic (buildd@crested) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012
Linux yuzhe-HP 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Here it shows the os is x86_64. To install oracle jdk over linux, install package comes with two versions x86 and x64. Which should I choose for a x86_64 system?
It is a 64bit system. Using the designation x86 only for 32bit architectures is not quite correct. There are x86 processors with 64bit architecture. More precisely there are two different architectures designated as x64: the Intel x86 with 64bit and the AMD64.

drivers - How do I get an Acer Npilfy 802.11 (BCM43225) wireless card working?
My Laptop is Acer 5742G with "Npilfy 802.11 wireless".
I have both windows 7 and Ubuntu 12.10
Earlier when I had Ubuntu 12.04, the wireless was working fine, but after installing 12.10 wireless is not working at all, although it is still working in windows.
I am not able to see "Wireless Networks" in the Network Manager nor in the Network Settings.
This was the output I got for rfkill
0: acer-wireless: Wireless LAN
Soft blocked: no
Hard blocked: no
1: acer-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
This is a snapshot of my Additional Drivers settings.
As you can see, the required driver for wireless is installed.
Your problem looks similar to mine, and I think the new kernel and broadcom drivers are the connection. I ran
sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
and it worked for me on a Samsung netbook.

networking - Wifi ridiculously slow on Ubuntu 16.04 LTS and a Frontier MI424WR Router
My Acer Aspire E5 575G has a Qualcomm Atheros QCA9377. I have tried reinstalling my kernel, I have reinstalled drivers(ath10k), installing backport, have turned off powersaving, have installed wicd, etc...
only thing that has slightly helped is disabling WMM in the router settings. My kernel version is 4.10.0-42-generic.
Typical speeds right next to the router are 15 mbps up and down. I have a 50/50 plan. 50+ mbps is my ethernet speed. when bluetooth is on, my mbps is half of the current slow wifi.
Here are some of the commands y'all often ask for:

nvidia - How can I improve battery life on my laptop?
I have a Macbook Pro 6,2. It uses Nvidia Optimus technology and would not work with Bumblebee as the i915 driver would fail. I had to uninstall Bumblebee, install nvidia-current, and blacklist nouveau and i915 to get my laptop up and running. So basically right now I'm running solely on my dedicated GPU which means I get only about 2:30 hrs of battery life.
Am I stuck with this short battery life until Nvidia provides proper support for their hardware?
Thanks.
Battery life in Linux sometimes tends to be shorter due to drivers not being able to automatically going into a sort of Power Saving mode.
Although the following suggestions won't change lots if your graphics card is on maximum power consumption permanently, I've found they've helped increase my battery life quite a bit:
Install CPUFreq
sudo apt-get install indicator-cpufreq
You will then be able to click on the icon to the right of the keyboard icon in this screenshot below (indicator bar):
And this should open up a menu like below:
The lower your processor speeds the less power it will consume, so either go with Powersave or put it on the minimum, this reduces battery power consumption especially well if you have a multi-core CPU.
Install TLP if you're running Ubuntu 13.04:
sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw smartmontools ethtool
For how to configure TLP in detail check the answers to this question on power-saving in 13.04 they explain more than enough for your needs I'd expect.
Install Jupiter if you're running 11.10, 12.04 or 12.10
sudo add-apt-repository ppa:webupd8team/jupiter
sudo apt-get update
sudo apt-get install jupiter
This applet can be opened using the lightning bolt in the indicator bar:
Or alternatively if it doesn't start up automatically you can turn launch it by typing jupiter into a terminal window (opened using Ctrl+Alt+T). Once you click on the lightning bolt you'll have the following menu open up where you'll be able to choose your power-consumption setting: 
Additionally in the devices tab you can disable wifi and bluetooth if you don't need them and would rather have more battery-life.
- Install powertop:
sudo apt-get install powertop
You run the app by typing in sudo powertop in the terminal and you use the arrow keys to go the far right column entitled Tunables, you should see something like this:
Using the arrow keys select each of the "Bad" settings and set them to "Good" by pressing enter, this should ensure your computer is using your battery in an optimal way.
Set Jupiter and CPUFreq on startup
Normally Jupiter and CPUFreq should start up automatically next time you reboot but if they don't all you have to do is go into start-up applications and type in the following:
- For jupiter
For CPUFreq
Obviously you can change the names and comments of the start-up programs to whatever you want as long as the command stays the same.
So in short to answer your question:
If it is your GPU which is draining your battery, then you have to wait on nVidia. However if any other component is also draining power the steps I've highlighted above will help you solve any problems and increase your battery life.
NB. Some information taken from the following sources:
Many thanks to both of them.
upgrade - System monitor detecting load averages higher in 12.04?
In 11.10 my load averages stayed around .06.I ve been on 12.04 precise for 3 days now and have noticed my load averages stay around 1.06 at all times.Can someone tell me what is going on?I was told that 12.04 precise was faster and efficient.Anyone else experiencing this issue?*update*I woke up this morning noticing my hdd was being accessed.I woke my computer and checked system monitor.My load averages were around 1.46 so it seems to be getting worse.This is the highest so far.I m running a quad core but I think at idle I should be like it was in 11.10,0.06.
How do I install Skype on Ubuntu 13.04? - solution found?

can anybody help?
Dear all - many thanks for your rapid responses. The answer provided by Qasim did the trick. Probably the other solutions were good too, but I may not have pressed the right buttons when trying them; Copy-pasting Qasim's commands into the terminal worked like a miracle - I had stuff scrolling down the screen for about 5 minutes but then Skype installed and I have already had my first conversation. Long live the AskUbuntu community. Cheers
Newest kernel stable or unstable?
I'm used to installing newest kernels on my machine.
I always keep an eye on the latest release from this site and now it says that the latest v4.2 is stable.
After that I'm used to downloading the kernel I choose from this site where now I can see that from v4.1 all versions are unstable.
So I'd like to know which one is telling the truth.
Thanks
They are both telling the truth. Having gone through 8 Release Candidates, the kernel.org version of 4.2 is considered stable. In about two weeks you will observe kernel 4.3 RC1 there, and the process continues.
Now, consider Ubuntu. Ultimately, the Ubuntu version, will have several changes additions and deletions that are not included in the mainline releases linked to. There are also patches applied to to the mainline for the debian packaging and changelog stuff in addition to kernel configuration settings. There simply must be a delay between the kernel.org version being declared stable and the actual Ubuntu version being created, tested on multiple and varied Ubuntu environments, and initially released. From the Ubuntu perspective the mainline PPA would never be considered "stable".
Edit bodhi.zazen
To some extent the confusion is coming from the terminology used by kernel.org and Debian/Ubuntu, specifically the terms unstable/testing/stable.
From https://www.kernel.org/category/releases.html
The terms used are:
Prepatch
Prepatch or "RC" kernels are mainline kernel pre-releases that are
mostly aimed at other kernel developers and Linux enthusiasts. They
must be compiled from source and usually contain new features that
must be tested before they can be put into a stable release. Prepatch
kernels are maintained and released by Linus Torvalds.
Mainline
Mainline tree is maintained by Linus Torvalds. It's the tree where all
new features are introduced and where all the exciting new development
happens. New mainline kernels are released every 2-3 months.
Stable After each mainline kernel is released, it is considered "stable." Any bug fixes for a stable kernel are backported from the
mainline tree and applied by a designated stable kernel maintainer.
There are usually only a few bugfix kernel releases until next
mainline kernel becomes available -- unless it is designated a
"longterm maintenance kernel." Stable kernel updates are released on
as-needed basis, usually 2-3 a month.
Longterm There are usually several "longterm maintenance" kernel releases provided for the purposes of backporting bugfixes for older
kernel trees. Only important bugfixes are applied to such kernels and
they don't usually see very frequent releases, especially for older
trees.
Distribution kernels
Many Linux distributions provide their own "longterm maintenance"
kernels that may or may not be based on those maintained by kernel
developers. These kernel releases are not hosted at kernel.org and
kernel developers can provide no support for them.
Debian takes code from upstream (kernel.org in this case) and packages it. See https://www.debian.org/doc/manuals/debian-faq/ch-choosing.en.html
Unstable has the most recent (latest) versions. But the packages in unstable are not well tested and might have bugs.
On the other hand, stable contains old versions of packages. But
this package is well tested and is less likely to have any bugs.
The packages in testing fall between these two extremes.
And then there is the Ubuntu kernel team's ppa, https://wiki.ubuntu.com/Kernel/MainlineBuilds
This last ppa provides the "mainline" , precompiled, for testing purposes.
So, when choosing what kernel to run you can:
- Obtain the source code from kernel.org, apply any patches you wish, and compile it yourself. You can choose:
Mainline - This kernel is the latest and most likely to have bugs.
Prepatch - This kernel is "pre-release" , or in the development cycle one goes Latest (unstable) -> Alpha -> Beta -> Release Candidate/Pre-release -> Stable release (terms vary with project).
Stable - Released code, less likely to have bugs, good for general use.
Long term - Very stable, at the sacrifice of new features.
or 2. Use a "distribution kernel"
Debian / Ubuntu then takes the source code from kernel.org , and applies patches, so the cycle repeats in what kernel.org would term a "distribution kernel".
The Debian/Ubuntu distribution kernel goes through a similar cycle Unstable -> testing -> stable
The kernel used by various versions of Ubuntu is listed here - https://en.wikipedia.org/wiki/List_of_Ubuntu_releases#Table_of_versions
So, at the time of release, Ubuntu is pulling from the "stable" upstream source code (15.10 is using kernel version 4.1).
At the time of this post, kernel 4.2 is the mainstream kernel, and thus not available in the Ubuntu repositories.
You can either compile the mainstream kernel yourself (I prefer this method) or install it from the ppa - http://kernel.ubuntu.com/~kernel-ppa/mainline/
These kernels are provided as is, as a convenient way for you to try the mainline kernel without having to compile it for yourself. It is unsupported and to some extent expected to have bugs.
They list the current mainstream kernel, 4.2, as unstable according to Debian policy (unstable -> testing -> stable)
As the other kernels listed there have undergone appropriate testing and patches they are eventually re-labeled as "stable"
