Public bug reported:
Distributor ID: Ubuntu
Description: Ubuntu Artful Aardvark (development branch)
Release: 17.10
Codename: artful
When using linux kernel linux-image-4.13.0-12-generic to linux-
image-4.13.0-16-generic Xorg fails to start with kernel error messages
below. Kernel boots and displays messages allows for GUI to enter disk
encryption key then tries to start Xorg login. Shows blank screen,
sometimes part of login dialog. Then hangs and goes blank usually
showing the low graphics mode error screen from Xorg and no
functionality after a while. Can ctrl+alt+f1 to console. Using linux-
image-4.10.0-35-generic everything works as expected. System worked
without issue with Ubuntu 17.04
Kernel error messages:
[ 43.836641] [drm] GPU HANG: ecode 8:0:0x00dfffff, in Xorg [1027], reason:
Hang on rcs0, action: reset
[ 43.836645] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 43.836646] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 43.836647] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 43.836648] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
