Xorg Freezes on my system

JanusPaul · 10-25-2009, 10:37 PM

Not sure why I get the same result between (amd64) debian, kubuntu, xubuntu, but the screen will pixelate once the desktop is fully loaded, sometimes when an app window opens like konsole/terminal.

I've tried various combinations, with & without the GeForce PCIx, even the live CDs freeze. Please trust me when I say I exhaust searching for what's already been asked/posted/resolved before posting, yes even google, I'm at a loss... It freezes like a kernel panic because Ctrl+Alt+F1 doesn't do jack, nor Ctrl+Alt+BkSp, would dmesg have logged anything useful?

A brief hardware list:

Dell Inspiron 531
Socket AM2 AMD Athlon64 X2 3800+
nVidia GeForce 7800 GT PCIx
nVidia MCP61 PCIx (onboard)

Thanks,
Paul

the latest Xorg have the ctrl-alt-bksp disabled by default. You need to install a package called something like "nozap" or similar. With it the ctrl-alt-bksp gets enabled.

Did you install the nvidia drivers? The nv drivers do not always work properly with nvidia cards.

didf you try 640x480x4BPP VGA mode to see if its the video driver?

Yeah I tried the nVidia drivers and everything loaded quicker, got to the same point and froze the same way. Correction though, the mouse cursor will continue to respond but that's it. Will try the "nozap" package thanks.

I don't think it's directly a video problem though. MemTest?

The alternative to <alt><ctrl><backspace> is <alt><printscrteen>k

Some idiot came up with the idea that users can press <alt><ctrl><backspace> by accident.

Running memtest will not hurt; at least you can eliminate a possible cause.
