logout switches to mirrored displays and resets display resolution to 1024x768

[Alexander List]

What I did?

* using my laptop (Lenovo Thinkpad X201 3626-A14) using builtin display at 1280x800
* login
* connect an external Dell 24" monitor using VGA
* Dell screen is detected correctly and used as secondary display using max resolution 1920x1200
* logout
* display is reset to mirrored setup using 1024x768
* login
* display remains in mirrored setup using 1024x768

What I expect:

* setup should not change unless I change it using Settings-> Displays or unplug the external monitor

Workaround:

a) plugin external monitor before login
or
b) unplug and re-plug monitor after login
