Thinkad w540 docking station and Linux Mint

Question

I have got Lenovo Thinkpad w540 and running Mint 16. When I dock the laptop into the docking station, everything freezes. I have to undock and wait until the login window is loaded. How should I go along about finding out what is wrong?

What I found out so far was the following. I ran the xrandr command before and after docking and there are differences. Is this causing me the problem? Without docking and the external monitor connected directly to the laptop:

$ xrandr 
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm

When docked, the external monitor is connected through the docking station:

$ xrandr 
Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 32767 x 32767

VIRTUAL1 disconnected (normal left inverted right x axis y axis)

If I try to run this command:

xrandr --auto --output DP2 --mode 1920x1200 && xrandr --auto --output eDP1 --mode 1920x1080 --left-of DP2

The screen freezes again and I have to switch off the laptop. Any suggestions?

The user who answered the question and then deleted the answer was actually right.

Upgraded my mint to 17 and now the freeze-problem is gone.
