I have just upgraded my system from 12.04 64 bit to 12.10 64 bit. The system was working well before the upgrade. I have read all about people having similar problems to mine so I have tried many solutions but none have fixed my problem.
The video card is a GIGABYTE GVR455D3-512
I have tried to run root commands such as:
sudo apt-get install nvidia-current-updates sudo apt-get install linux-headers-generic sudo apt-get install linux-source sudo apt-get install unity sudo apt-get install ubuntu-desktop
I'm at a loss of what to do next and as I convinced my family to do away with Windows, it's getting mighty hard to keep them to stay with Linux when we have not had an upgrade that has not had some sort of problem. This is day 3 and we still don't have a computer to use, I'm using my old work laptop that is running Ubuntu 12.o4 to type this message.
