I am using Ubuntu Gnome 14.10 64 bit on Dell Inspiron 3521. I have ATI Radeon 7560M HD Series Graphics Card. I tried installing ATI Graphics card in different ways.
1)Selecting fglrx from Additional Drivers under Software & Updates section
2)Selecting fglrx-updates from Additional Drivers under Software & Updates section
3)Downloaded latest ATI Driver (amd-catalyst-14-9-linux-x86-x86-64.zip) from AMD website and installed it.
Before trying every option, I uninstalled older drivers completely.
In every option, after reboot, all I got is a text console. Couldn't able to get into Display at all. Is there any driver working for Ubuntu Gnome 14.10 ? How can I get it and install it ?
The primary reason for me installing is the battery backup. Its hardy 40 mins on Ubuntu where as its 4+ hours on Windows. I want to install ATI Graphics card driver and disable the Discrete graphics card and enable only Intel graphics card so that battery back up will be better.
Please help. Thanks in Advance.
Update: This is the error I am getting
/usr/bin/X: symbol lookup error: /usr/lib/x86_64-linux-gnu/xorg/extra-modules/modules/extensions/libglx.so: undefined symbol: LoadExtension
Xinit: giving up
Xinit: unable to connect to X server: Connection refused

Update2 : Tried amd-catalyst-omega-14-12-linux-x86-x86-64.zip but no luck
