** Description changed: 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. - If any additional information is needed I'm happy to provide it. - - ProblemType: Bug - DistroRelease: Ubuntu 14.04 -
