Title:
X server crashes sporadically with a segfault
Status in xorg package in Ubuntu:
Incomplete
Bug description:
My desktop session crashes sporadically. Often this happens when I
leave the computer and the screensaver starts (Euphoria GL
screensaver). This bug is not reproducible on demand.
Attached is my Xorg log file which seems to indicate that this problem
is related to the i915 driver code.
