Hello,

I would like to know if I am the only one with this issue or not. I
recently discover how to reproduce my X session crash because of
gkrellm-hdplop plugin in GKrellM v2.3.1.

I basically loaded up GKrellM2 (doesn't matter if it uses defaults or
customized) with gkrellm-hdplop plugin running only on ONE virtual
desktop in KDE v3.5.8 or Gnome v2.14.3. Then, I switched to another
virtual desktop that didn't have GKrellM on screen. Finally, I pressed
ctrl-alt-F# (# is a number like 1) to go back to console/text mode.

It resulted a X crash like:
Backtrace:
0: /usr/bin/X11/X(xf86SigHandler+0x81) [0x80c89c1]
1: [0xffffe420]
2: /usr/bin/X11/X [0x81771e0]
3: /usr/bin/X11/X [0x814a8ba]
4: /usr/bin/X11/X [0x814b504]
5: /usr/bin/X11/X [0x8154c1e]
6: /usr/bin/X11/X(Dispatch+0x1a1) [0x808eff1]
7: /usr/bin/X11/X(main+0x47e) [0x8076e2e]
8: /lib/i686/cmov/libc.so.6(__libc_start_main+0xe0) [0xb7dc5450]
9: /usr/bin/X11/X(FontFileCompleteXLFD+0x1e9) [0x80761b1]

Fatal server error:
Caught signal 11. Server aborting


If I disable this neat colorful plugin, then I won't get the crash. I am
just wondering if I am the only one with this problem. I am using Debian
(Kernel 2.6.22-K7) and keep it updated daily.

Thanks in advance. :)

I wonder if this problem still occurs with: startx -- -dumbSched

By default XFree86/X.org use a "smart scheduler" that uses SIGALRM
periodically. You might try without that, even though you're
experiencing a signal 11 which is a SIGSEGV.

By the way, do any X developers know why dispatch.c doesn't use
sig_atomic_t instead of the volatile char code? IMO sig_atomic_t is
better for variables used in signal handlers.

Try to get a debug build of the X.org X server. I think then you will
be able to see symbol names for the addresses likes 0x81771e0 when
xorg_backtrace() dumps the backtrace.

From what I've read of configure.ac for xorg-server, it seems that you
want ./configure --enable-debug

The default is --prefix=/usr/local so you may want to backup your X11
install, and then try ./configure --enable-debug --prefix=/usr

OK... I am starting to think this is NVIDIA's fault. I went back to nv
driver by renaming /etc/X11/xorg.conf and run startx. I tried to
reproduce the problem and no crash with gkrellm-hdplop plugin! I am
going to report this to NVIDIA via e-mail and the forum.

Is it me or is NVIDIA driver getting buggy in Linux like in Windows? :(

As far as I can tell, the NVIDIA driver for Linux shares code
with the Windows driver. Look at the version numbers.

As for bugs, read the forums. Hell yeah there are bugs.
The good news is, if you post the bug to the forums,
you might find a work around and eventually it will get fixed.
