Just installed Kubuntu 16.04, fully updated as of 4/22/16
Noticed these two errors in KSystemLog:

Title:
xorg crashes because of intel gpu driver
Status in linux package in Ubuntu:
Expired
Bug description:
Suddenly and without any warning the screen became blank and lightdm
rebooted. I have found these interesting lines in dmesg:
[14137.598202] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR*

This *may* be related to screen switching (undocking/docking of the
notebook with an external monitor attached), but I am not sure at all.
