I don't know a good way to get the log when I try to change the resolution, all I got, I put it there:
http://fpaste.org/paste/9969

Hope that helps :)

Oh and also the computer has trouble to shutdown... I have to press the button quite often (cannot give statistics though, it's twice in the row there but I don't remember if it was always before)

Ok so I managed to get the resolution of the screen right on track.

I plugged in the external screen, switch on the 21", set its resolution, change the resolution of the screen of the laptop back to 1024x768 'Apply' and it works.

Only problem, if I reboot I lost the changes and I have to redo this trick again (problem I only have the 21" at work...)

I now have managed to come back to original stage.

I created a new user and saw that the resolution was correct for this new user, so I remove some of the ~/. files and folders, restart and every thing is back to normal here :)

I leave the bug open (the bug did exist) but the situation is fine for me here

Ok I clearly identified the problem,

It comes if I switch the screen to a refresh rate of 60MHz, I have no problem if the refresh rate is at 50Hz.

Hope that helps :)

The laptop is running rawhide without xorg.conf 

I hereby attach the logs

Not quite the same but similar:

General desktop cruising caused this, see attached pic.  System was hard locked, vt switch failed, mouse was locked.  F11 Rawhide all updates to date.
