Recovering ubuntu from graphics card crash
I have a dual boot system (XP/Ubuntu) and have had a graphics card crash on me. I have installed a new graphics card (after the first one stopped responding) and I am able to boot into windows no problem. The new card is a Gigabyte ATI Radeon 4650 HD. I did install an ATI catalist control center in Ubuntu under the old card but Ubuntu complained I did not have any ATI products installed so I think I uninstalled it (I was about to start installing drivers when the old card crashed).
When I currently try to boot Ubuntu the moniter is black except the top 1cm that is garbled pixcles. This is the same problem that I had with the old card but the old card stopped displaying the POST or windows so I believed it was the card and not both OS's.
I have tried using recovery mode to fix broken packages, graphics and the file system. I have also tried to use the installed version of Ubuntu (ie not the latest upgraded version) and still the same problem.
The last thing I have tried is booting from the live CD and that loads with no graphics problems.
How do I get Ubuntu to realise I have a new graphics card and use it correctly.
Solution 1:
The first thing to try is dpkg-reconfigure xserver-xorg
