I have a laptop (Acer TravelMate 8471), which I connect to an external monitor, keyboard etc. when I'm at home.

When I unplug my laptop, I have to remember to go to the Monitor Preferences and turn off the external monitor, and turn on my laptop monitor, otherwise X will crash.

When I plug my external monitor to my laptop, it will automatically switch to that one without any troubles.

I'm running 10.10, and I have an intel graphics card (GMA 4500 I think; i915).

You should report an X bug.

Will do then :) I thought it might have been a solved problem. – LasseValentini Apr 27 '11 at 7:06
I have a similar problem, did you end up finding a solution? – Dor Shemer Jun 22 '12 at 22:49
