Upstream indicates that it is a userspace application that triggers the crash.
So that suggests this approach to debug: * Identify an application that reliably causes the crash (such as gnome-panel or gnome-terminal) * Terminate that process * Restart it using strace, capturing output to a log file * Reproduce the X crash * Attach the strace to this bug report. (Fwiw, I haven't been able to reproduce this bug myself... it would be helpful if someone could better isolate the conditions and steps to reproduce the problem. Also maybe look for commonalities between individuals experiencing the same issue, in case it is hardware-specific in some sense.) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. https://bugs.launchpad.net/bugs/682712 Title: x server crashes with: [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a purgeable buffer _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
