This would be a good start: gdb /usr/X11R6/bin/Xorg /path/to/Xorg.core bt Trying it with your file on my system it looks like it's crashing in sna_poly_fill_rect_stippled_n_box in intel_drv.so, but my binaries may not match yours, so this may not be correct. The Xorg.0.log looks clean so it might be from after a restart - there might be something in Xorg.0.log.old. I would recommend removing the core file from the webserver, it's a dump of the whole memory of the failed Xorg server process so it might include something you don't want kept around.
