11.10 - Can't boot from USB after installing Ubuntu

I bought a Samsung series 5 notebook and a very strange thing happened: I installed Ubuntu 11.10 from a usb pen drive but when I restarted (I cleared the existing partitions) I stopped being able to boot from any USB device, whatever I change at BIOS, it always goes straight to GRUB2.



Just to add something to the mix, now I can't boot properly after upgrading to Precise (separate question)

13.04 - HDMI support and Nvidia Optimus systems

I see a few questions and talks of a new NVIDIA driver that allegedly supports Optimus technology, by Nvidia. I use a Dell Vostro 3500 Core i5 4GB RAM, with an Intel Video Card and a Geforce 310M GS. The systems: Ubuntu 13.04 / Win 7 (dual-boot).




My question concerns HDMI support with a video card similar to the one I have. Even with Bumblebee installed, when I had Ubuntu 12.10 running, I couldn't switch to HDMI external monitors. That's the only reason why I still use dual-boot. I would be happy even if it's possible to make HDMI working only with the Intel card.



Has anyone ever tried the new 319.12 driver by NVIDIA on Ubuntu and saw any significant difference, specially concerning HDMI support? Has anyone ever succeeded in connecting HDMI external monitors using NVIDIA drivers, with or without Bumblebee? Thanks in advance for sharing your sollutions.

Unable to resume Windows 10 after hibernation in a dual boot PC

I left my PC turned on last night, in Windows session, and when I returned home it was off (I guess it was because of hibernation). So I turned it on again, logo of BIOS appeared as usual, GRUB options appeared as usual, but then, whether if I click on Windows or Ubuntu, the result is the same: A black screen and nothing happens after.



I have discovered that I can log into Ubuntu if I go to "repair options" and click on update grub option, but just once, because once I reboot PC, the same happens again. If I try to access Windows partitions while in Ubuntu, it says that they are hibernating (I had to do some process I can't remember to allow Ubuntu recognize them though).



I have tried reading about similar problems, but they all suggest logging into Windows and turning off hibernation, but I can't log into Windows.

Trying to get apt-upgrade working again on Ubuntu Server 16.04

My Ubuntu Server runs in a virtual machine. Unfortunately the server it runs on was restarted recently, causing corruption which required a full disk fsck to get it booting again.



When I tried to update and upgrade packages, I got error messages which I include below. apt update works as usual but the apt upgrade command causes an error. When I run dpkg -- configure -a, I get other error messages. I have tried removing and purging the packages mentioned but nothing seems to work.



I have tried the solution suggested but get the following error message:

Any ideas? This screen has the original errors...

12.10 - GRUB missing after removing drive with Ubuntu

My work laptop is an HP EliteBook with one hard drive in it. On that hard drive is a encryption program that boots up called "safeboot", you enter your username and password and then Windows boots up. Wanting to use this for personal use I removed the CD drive and installed a 2nd hard drive bay instead. On the 2nd hard drive I loaded Linux Mint 14 and was using it for months. Then I wanted to try Ubuntu 12.10 so I partitioned the 2nd hard drive and installed 12.10. Now when booting up if I choose to boot from the first hard drive it goes straight into the grub boot loader. If I remove the 2nd hard drive and boot up it says grub is missing. Any thoughts?

How to add Minecraft to the Unity launcher?

I'm having trouble getting Minecraft to launch when I add it to the launcher. If the game is running, I can right click on the icon in the launcher and select "keep in launcher" and the icon stays, but the game won't launch from it.




If I create a launcher on the desktop, then drag that launcher to the unity launcher, the game will start. If I remove the launcher from the desktop, it stays in the Unity launcher, but will not start any more.



Is there some way to add it to the Unity launcher so that it will actually launch?



(Blech, I've said launch far too many times.)

12.04 - Can't use nvidia driver



I have a NVidia GTX 765M video card in my notebook running Ubuntu 12.04.2 and can't figure out why it doesn't use nvidia driver. I've installed nvidia-current and nvidia-settings from this repository:




ppa:ubuntu-x-swat/x-updates


however when I run nvidia-settings this message is shown:



You do not appear to be using the NVIDIA X driver. 
Please edit your X configuration file (just run `nvidia-xconfig` as root),
and restart the X server.



Before run nvidia-xconfig I've looked the /etc/X11/xorg.conf and it is completely empty.
After running nvidia-xconfig the scree has as maximum resolution 640x480, and the same message appears when I run nvidia-settings.



ADDED



When I run lspci | grep VGA just Intel card is found:



00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06)



NVidia card is returned when I run lspci | grep 3D:



01:00.0 3D controller: NVIDIA Corporation Device 11e2 (rev a1)


What can I do to make this video card run using nvidia driver?



This looks like your laptop is using NVidia Optimus, which is often rather troublesome in Linux.
Basically what this means is that the system will use an integrated Intel HD Graphics card by default, and when you tell it to, it will switch to the NVidia card.



I'm not highly knowledgably about the subject, but this is what came to mind.




I think your best option is probably to look in your BIOS/UEFI for an option to use the NVidia card by default, if the issue is indeed NVidia Optimus.
