Description
The bug has been reported on https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1421575
"Thinkpad X220 running vivid up to date.
Usually sits in docking station with external monitor.
Today I ran the laptop outside the docking station, and plugged it into the dock while running (which worked fine forever on utopic) but today it now freaks out.
I deleted ~/.config/monitors.xml to reset my display config
I restarted and logged in with both monitors active.
As soon as I change the display config doing the display corrupts, flickers and becomes unusable.
