    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

            I do not agree with what you have to say,
            but I'll defend to the death your right to say it.
