[Bug 1560524] Re: Latitude E7470 crashes in DRM driver after connecting to DELL EPORT docking station
I have reproduced it too, in 14.04 dock station (with display/s
connected) hangs the laptop and it doesn't even boot if it's docked. But
HDMI seems to work perfectly.
In 16.04 beta 2, connecting/disconnecting an HDMI display hangs the
laptop. When it's connected to the dock while it's running it uses to
hang too, but it sometimes works, or hangs after some seconds. It seems
to work fine if no change is done in displays configuration while it's
running. So the general situation improves a bit, except for HDMI that
is worse in 16.04.
