Description of problem: I had a perfectly working T400 with a Fedora 12 installation which I upgraded recently to F13. Now I get logged out as soon as i connect an external screen. I assume X crashes, but there is nothing in Xorg.0.log ... Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.11.0-2.fc13.i686 [fm@thinkpad ~]$ uname -a Linux thinkpad 2.6.33.2-57.fc13.i686.PAE #1 SMP Tue Apr 20 08:58:17 UTC 2010 i686 i686 i386 GNU/Linux How reproducible: 100% Steps to Reproduce: 1. get an external monitor 2. attach it Actual results: I see gdm on both screens.

It somehow changed. I do not get the login screen anymore but the screen goes just black. I can still move the mouse and change to tty2. Killing X gives me a display again. Will attach a new log shortly. I would certainly appreciate some help, what to try and provide...

Ok, I have found out with the help of nickle in the #intel-gfx channel on freenode that this is a problem of compiz. Exchanging compiz with metacity solved the problem for me. According to #intel-gfx compiz seems "not to respect the max renderbuf size"...
https://bugs.freedesktop.org/show_bug.cgi?id=22076 might be a related upstream bug.
This seems to be solved by intel 2.12 which i got from Koji. As I am on F14 now I cannot reproduce anymore.
