[Bug 1486140] [NEW] No login with lightdm possible when on the dock

[Jens Herrmann]

Public bug reported:

Two days ago I did the upgrade to Xubuntu 15.04 on my neighbors Dell
D620. Since the upgrade I am not able to boot the laptop when on the
docking station (with 90W power supply). All I get is a white screen
with the mouse cursor in the centre which I am able to move. When I boot
the system without the docking station everything works fine. I have now
changed the default login manager to gdm and everything works fine also,
on and off the docking station. This is reproducable always.
