Title:
GPU Hang in Xorg rcs0 drm/i915
Status in linux package in Ubuntu:
Incomplete
Bug description:
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:
