Bug Description

Binary package hint: xserver-xorg-core

I've had several X crashes overnight, so I assume
they're induced by the screensaver. I'm running
Gnome, so I suppose it's gnome-screensaver.
I'll attach a gdm log.

This is in up-to-date ia32 edgy with the nv X module

 I guess I'm the fourth person with an X crash in FontFileCompleteXLFD.

 I have a Core 2 Duo on an Intel DG965WH (g965 graphics), running AMD64 Ubuntu Edgy. 3D was fine (except for no s3tc) with the i965 driver. Then I put in an r128 AIW card and enabled Xinerama, which disables DRI. (And I guess any indirect accel, too.)

 Now googleearth (an ia32 binary; installed from the medibuntu repository) crashes my X server while starting. This seemed very repeatable, and happened even with latest upstream xf86-video-intel. (ge is a 32bit app that comes with its own libraries, so it wasn't using the 64bit libdrm or mesa client-side libs I compiled.) (The Xorg.0.log I attached was with the Edgy versions of everything, though.) Some other GL progs, like glxgears and tuxkart, ran without crashing (tuxkart slowly, glxgears pretty fast on this CPU :).

 And with Xinerama disabled, running glxinfo on the second head (r128) makes the server segfault! That screen (:0.1) wasn't using DRI. I think the root cause was that the r128 kernel module wasn't loaded. Maybe there's another bug here somewhere, since X should cause the dri module to load like it does for i915 for the first head.

 The server's i810_drv.so is v1.7.3, that I compiled myself, and the client libGL and libdrm are also the latest git versions that I compiled locally. The only files outside of /usr/local that are locally compiled are i810_drv.so, and /usr/X11R6/lib/modules/dri. No, that isn't where ubuntu puts r128_dri.so, but that's where mesa 6.5.2 in /usr/local/lib looks for them...

 Err, /usr/lib/dri/* is from libgl1-mesa-dri, which I built locally from Ubuntu source, because I needed to compile with -fno-strict-aliasing for the i965 driver to work.

 Anyway, I'll attach my Xorg log file in the hope that it's of some use even though it's not with the Ubuntu versions of everything. It's a big pain to use Edgy's i810_drv.so, because it screws up the vid mode.

 I'll send this now before I do anything that risks crashing X and losing what I've typed in firefox, since I'm not running it in Xvnc or anything!

I saw this again on my system, this time on a single-head setup with just the r128. Again while running googleearth. This time the server wasn't able to recover from the segfault and restore text mode, and went into an infinite loop. I had to send it a SIGKILL before it would die. Xorg.0.log is 3.8GB (although 7zip takes it down to 568kB, an impressive factor of 7000).

 Google Earth ran ok once (although flickery). I turned off aniso filtering and reduced the detail level, and set texture depth to 16bit. Then I exited and started it again. This time X froze while its splash screen was up. I sshed in from another machine to kill it, but the X server kept writing its log file (and the kernel log file was growing too; up to 218MB).

It's probably important to note that the r128 card was not the system's primary vid card. The text console was on the internal g965, and that's the hardware the BIOS POSTed; my BIOS is explicitly set to use the internal vga as the primary VGA device.

 X servers that start after the nasty hang that required SIGKILLing the X server all crash. They seem to be using the g965 video BIOS with the r128, even though the r128 is the only device configured. There's a line in the log like
(II) R128(0): VESA VBE Total Mem: 262080 kB
(II) R128(0): VESA VBE OEM: Intel(r)Broadwater-G Graphics Chip Accelerated VGA BIOS
 *snicker* that's some confused hardware. A reboot took care of it...

 Also, all X backtraces seem to include FontFileCompleteXLFD. I was confused before about which direction the backtrace was going and thought it was significant; F.F.C.XLFD is somehow showing up as the parent of _libc_start_main. So X must do something to the stack that the backtracer doesn't like. It's obviously not significant that all the backtraces have the same parent, since it's the same program. Sorry for any confusion.

I find X crashes at least a few times a day, although it has yet to happen when
I'm actually using the system. X is almost always restarted when I come to my
computer in the morning, and frequently again in the evening when I get home.

I discovered my uptime was 6+ days, and ruled out the reboots I thought had been
happening.

Courtesy of a similar bug reported to Ubuntu:

https://launchpad.net/distros/ubuntu/+source/xorg-server/+bug/75592

I took a shot and disabled xscreensaver.

Voila. Haven't had a crash since. Mind you, while this stops the crashes, I'd
obviously like to be able to use the screensaver function. Just thought I
should mention it in case it helps towards a resolution.

Cheers,

Tremaine

I think I can add a vote for the screensaver triggering the problem in my instance. Based on the initial reporters experience I disabled my own xscreensaver and haven't had a crash since.

That said, I do rather hope this gets fixed as I rather like having a screensaver that will lock my station when I forget to do it myself.

I just removed xscreensaver-gl, not xscreensaver itself.

Some of these crashes (at least Peter's) are probably bug #60288. Please try the test package in that bug report if you can.

Dave, Peter, and Tremaine, each of you have different graphics systems and drivers (-nv, -intel, -ati), but all seem to be getting crashes in mesa (libGLcore.so and libglx.so).

I'm able to reproduce this crash using the screensaver under gdm.

Bryce, your backtrace looks similar to bug #153986, and not so much like Dave's backtraces here.
