[xrandr+intel] System freeze after trying to turn on external output after hibernation

[Łukasz Maśko]

My laptop has an Intel 945GM graphics and it mainly works fine (xserver 
1.7.2, intel driver 2.9.1, libdrm 2.4.15 and kernel 2.6.30.5). There is one 
problem, which occurs only in one situation (at least I think so for it is 
hard for me to repeat it several times during a short period). 

At home I have a docking station with DVI output and sometimes I use an 
external LCD connected with it. Xrandr uses DVI1 output then.

In the same time, the laptop itself has a VGA output, which I use at work.

I've noticed, that if I use my laptop at home (DVI1 output available but 
always off when hibernaiting), hibernate it, connect it to the screen at 
work (now DVI1 is not available, but VGA1 is) and try to activate it using 
xrandr, my machine freezes and is completly dead. Also nothing appears in 
system logs. I have to reboot it and then everything works fine again (but 
now I don't have a DVI output and monitor to check if it is repeatable).

I'll try to check it the other way now: VGA works at work now, I'll 
hibernate my machine and check, if DVI will work at home without problems.

Does anyone else came across such situation? It seems to be a bug, but 
before I fill in a bug report, I want to make sure.
