Comment 3 for bug 888134

Apologies for the delay in replying. Here's a more exact description of the problem:
1) Try to use external monitor by plugging it in
2) Monitor gets enabled, but monitor layout is wrong
3) Open gnome-control center to the Displays section
4) Re-arrange monitors, hit "Apply"
5) Screens blink and flash for 5-10s, and end up back in the original (wrong) layout afterwards. I can't tell if it temporarily gets the right resolution or not.

I tried to run apport-collect, but I'm not sure it did anything:
