i commented it out and I could log out!
do i have to worry that I am not using it?
The line Load "dri" in xorg.conf ? It has something to do with direct-rendering, but I dunno if it is a must... See the thread "Fc2 id damn slow" - one list-member had a slow KDE and uncommenting the dri-line solved the performance issue...
