Description Felix Möller 2010-04-27 12:41:09 UTC 
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.

Expected results:
I keep my desktop and it is expanded to the other screen.

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.
Comment 8 Felix Möller 2010-07-28 14:43:50 UTC 
This seems to be solved by intel 2.12 which i got from Koji. As I am on F14 now I cannot reproduce anymore.
