Xorg freeze on Ubuntu 7.04 with 6800GT
I am totally frustrated. If I use the latest stable nvidia driver on Ubuntu Feisty Fawn, I can log into a normal user session. But after about 1-10 minutes, I recognize that my keyboard does not work anymore and some time later the whole server is freezing. I logged into that machine via ssh and created the attached bug report.
I do not know, if my graphics board might have been damaged, when I recently cleaned it carefully. At the other hand, after getting the X-server freeze, I rebooted into Windows XP and played Doom3 in Ultra quality for several hours without having any problems. So the question is: Can a graphics board have hardware problems, which are recognized under Linux but not under Windows?
Is there some diagnostic tool under Linux/Windows, where I can do a full check of the hardware?
