Screen display yellow and streaky
When I started my laptop today, my screen display was yellowish and streaky - sort of like a crayon drawing. I rebooted several times and nothing changed.
I decided at the login screen to reboot the x-server, and this seemed to fix the problem, but now, a few minutes later, everything turned yellow and streaky again, and then a minute later reverted to normal.
Does anyone have any thoughts on what might be causing this to happen and what I can do to troubleshoot it?
I am running Kubuntu 8.04 on a dell c610. My video card is an ATI radeon, according to the system specs.
Could the video card be going bad?
