Hi all, For several weeks now, I've been having X lock up on me occasionally, and I'm a bit stumped as to where to start debugging it...
I'm running Sarge on a P4 3.2 HT, and my video card is a GeForce FX
5200 using the nvidia binary driver. I've had this problem on both a
home-rolled 2.4.22 kernel and the Debian 2.6.7-SMP kernel-package.
Every couple of days or so X seems to die an abrupt death. The display
will freeze completely, keyboard input has no effect (including
CTRL-ALT-F1 and CTRL-ALT-BACKSPACE). The system is still running,
though: If XMMS is playing when the problem hits, the music keeps on
going; and I can ssh in to the box no problem. If I kill -9 the XDM and
/usr/X11R6/bin/X processes then the screen goes black... but then doing
/etc/init.d/xdm start just silently fails. So I've been ssh-ing in just
to reboot the box.
Now, I've had this happen while I was surfing the web, and while the
screensaver was running, and sometimes after the monitor has gone to
sleep (oh, and once in the middle of a game of armagetron).
A "tail" of XFree86.0.log shows a bunch of GetModeLine entries, but
nothing that looks like error or panic or "ack! I'm dying!"...
I've done an 8-hr run of memtest86 with no complaints at all, the
temperature seems to be happy, and loading the crap out of the system
doesn't make it fail (I tried 5 hours of a kernel-compile loop, and 2
hours of cpuburn with no problems).
So where do I start looking to figure out what's causing this and/or to
fix it.
Thanks for any help
