(In reply to matthias.a.lee from comment #27) > Is there a build including that patch or will I have to build it myself?
As an upstream we don't provide builds, you're expected to be able to apply and test patches. Sometimes your distro developers may be able to help. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1436590 Title: Intel Display i915 driver crashes, Thinkpad X1 carbon Gen 3 Status in X.org xf86-video-intel: Incomplete Status in xserver-xorg-video-intel package in Ubuntu: Triaged Bug description: - start ubuntu 15.04 and log in - use CTRL+AL+F2 to switch to TTY2.
