I have a Asrock z77 Extreme 4 with a nvidia GTX 560 Ti video graphics card and I recently bought built it about six months ago. I have installed Ubuntu 12.10 64-bit on it (I installed the 32-bit first).

Over all, the graphics look pretty good, but there are a few issues I wanted to see about fixing:

When getting into Software Center there are major glitches in the icons and the text. I am able to use it, but in a lot of cases I am not able to read the details or reviews of the software information page.

It also does something similar every once in a while with other programs, such as file manager, Library Office, and System Settings but not near as often as the Software Center.

It freezes when using Super+S.

I have done a lot of research and stuff but I can not find the solution. I know it has to do with the graphics drivers and I tried following the directions from this link because it claimed to work with my graphics card but when I rebooted I got a black screen so I just ran the install disk again http://podzemski.com/2012/10/20/ubuntu-12-10-nvidia-drivers/.

I have tried other methods that changed the aspect ratio and the resolution and made it look really grainy Nvidia driver doesn't work in 12.10. My proper aspect ratio and resolution is 1920x1080 (16:9)

I have run all the updates and everything is up to date. There are no additional drivers that it asks for, or anything like that.

I am familiar with Ubuntu but I am no where near an expert.

Any help is welcome.

Just in case, what Nvidia driver version are you using, what monitor/TV are you using and have you tried a lower resolution like 1680x1050? –  Luis Alvarado Dec 5 '12 at 1:18

If you have a nvidia card and want proper use of it you will need the nvidia driver! Concentrate your efforts there. Is there something 'not standard' about where/how your graphics card is installed? E.g. I used to have a motherboard that listed the pci numbers backwards. The nvidia installer can fall down in such cases, especially with 2 graphics cards. If you get a black screen

Ctrl+Alt+F2

login and attempt to fix/work out what is going on. If necessary you can uninstall the nvidia driver and reboot to get back to x.
