My wife's XFree86 was randomly crashing every once in a while. Not a good thing.
I tracked it down to xscreensaver. I used xscreensaver-control and manually tried different savers. It crashed on GL-related savers. Also, X crashes when running glxinfo.
I read several postings about this, but no real answer. I also didn't find anything the same in bugzilla. (307 seems similar).
When X crashes, it has a Segmentation fault and signal 11.
I received no other usable (as far as I can tell) output related to crash from xinit nor in the /var/log/XFree86.0.log.
Her system is running Linux 2.6.3 kernel.
Linux agpgart interface v0.100 (c) Dave Jones agpgart: Detected an Intel i815 Chipset. agpgart: Maximum main memory to use for agp memory: 93M agpgart: detected 4MB dedicated video ram. agpgart: AGP aperture is 64M @ 0xe8000000 [drm] Initialized i830 1.3.2 20021108 on minor 0
So, is it an i81x or an i830/i845/i865? The X log seems to indicate i815, but the i830 kernel module is loaded. Try using the i810 kernel module.
I have tried with and without i810 module.
XFree86 is 4.4.0 (as installed from pkgsrc).
/var/log/XFree86.0.log says:

...
(**) I810(0): DRI is disabled because it runs only at 16-bit depth.
I also tried 16-bit so i810 DRI would stay enabled. But that didn't help. The GL-related use still crashed X.
What should I do so she can use GL applications?
In the mean time, try setting LIBGL_ALWAYS_INDIRECT in her .profile (or whatever) or disabling DRI.
