Backtrace from the core file
I was trying Dave Airlie's new DP MST patches
(<a href="http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-i915-mst-support">http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-i915-mst-support</a>) on my
T440s with two monitors with different resolutions connected via an ultradock.
This segfault occurs always when I un-dock the laptop from the dock. I guess
this is relavant: while undocking, the gnome-settings daemon tries to configure
X to use just the laptop's display through xrandr and that is where the crash
occurs.
Previously, I tried 2.99.912 version which crashed upon changing the
orientation of a connected monitor through xrandr. This current git master
(b3d3c0e8e75) does not have this problem.
