Bug Description
Binary package hint: xserver-
When I connect an external monitor while being logged in, and subsequently trying to use it, either by pressing f7 or running xrandr or opening system -> preferences -> display, the displays freeze.
I can still remotely log in (via ssh) and look around; however, I could not kill the X server even with SIGKILL nor make a core dump.
I'm including the Xorg.0.log, which ends at the time of the freeze. Also included is a snippet of kern.log that may be relevant, and the output of lsof for the X process.

I can confirm this problem on a Lenovo ThinkPad X60 with Intel graphics. If external monitor is connected at startup it is possible to use it, but only if monitors are mirrored (to lower laptop sceen resolution) or the Laptop screen is turned off. Trying to activate both monitors at their respective resolution crashes the screens.
