After a while, regardless of desktop effects/other things going on X will crash. The system is stable with the "nv" driver.
// the instabilities seem random, I had it up for about 2 and a half hours once, but normally it goes down within 10-15 minutes. It does not seem related to system load/heat at all.
I've tried gentoo (~amd64, unstable tree, kernel 2.6.33-rc1 and xorg 1.7.3) and ubuntu (+ kubuntu) stable.
I've tried multiple drivers, the stable ubuntu one, and from the vdpau ppa overlay (latest 190 and 195 including 195.30 recently released) and they all have the exact same problem.
Update : 173 driver seems to be stable, both with "UseEvents" on and off. I've used it for about a day now and it seems solid, slow, but solid. Attached working nvidia-bug-report as well.
Update 2: Testing 32bit+-PAE in post #14.
- Computer is "stable" with 32bit with or without a pae kernel, so this is 64bit related. I use "stable" because I get nvrm problems instead on 32bit. Could be the same problem that crashes in 64bit and causes nvrm in 32bit? Workaround in post #58 works on 64bit.
Fixed in 256.29, for AC power, still breaks on battery.
I've got a alienware m15x with a gtx260m display adapter.
There's a apport automatic bug report here : https://bugs.launchpad.net/ubuntu/+s...er/+bug/498708
And both kubuntu and gentoo nvidia-bug-report's attached.
//edit, adding 180.60 and 190.53 bugreports on gentoo, both drivers crash the same way as the newer drivers.
In post #58 : http://www.nvnews.net/vbulletin/show...6&postcount=58
This is the same problem as in http://www.nvnews.net/vbulletin/showthread.php?t=142695
, but it contained information as I was testing and the topic is misleading.
