Arch Linux

Description:

This is observed on a Lenovo Thinkpad T420 with intel graphics. I frequently see the XServer crashing, in particular after resume from standby but also at other occasions. This sees to be happening mostly when an external monitor is connected to the DisplayPort connector.

I have tried to get traces by compiling xf86-video-intel with debugging symbols, but if I do so, the xserver fails to start altogether, so I can only present the gdb log from the stripped packages, which, probably isn't too helpful. Any idea what I can do to generate traces nonetheless?
