Xorg crash

[Espen Stefansen]

Xorg crashes several times a day. Sometimes within minutes of each other.

This is a laptop and i use an external monitor, along with the laptop screen. It's an intel graphics card.

Here's the backtrace from Xorg.0.log:

I have a similar problem - x11 crashes several times a week. I also use an external screen on my laptop. I have an nVidia NVS 3100M, driver version 275.09.07. Xorg version 1.7.6 (10706000).

This is _extremely_ annoying as I lose my open applications and unsaved work every single time.
