Bug Description
The i915 driver crashed on Kubuntu 16.04 beta 2 on a Lenovo Thinkpad X1 3rd generation.
I think the crash happened when KDE attempted to perform automatic login. After the crash, I believe X was restarted. The login screen was shown and I could log in and use the computer normally.

I believe this bug has some similarities with freedesktop bug https:/ /bugs.freedeskt op.org/ show_bug. cgi?id= 91960 and launchpad bug 1555078.
