Xorg segmentation fault after upgrading to F17

view story

http://forums.fedoraforum.org – Hello Everyone, I upgraded Fedora 16 on my machine to Fedora 17 and after upgrade I have the following problem: When I resume the machine from standby and enter my password to unlock, the desktop appears but suddenly logs out and I will be returned to the main login page and I have to log back in again. I am not a professional but to the best of my knowledge the reason is a segmentation fault in Xorg as the logs in /var/log/Xorg.0.log.old suggests: Code: [ 13209.053] (II) intel(0): EDID vendor "LGD", prod id 738 [ 13209.053] (II) intel(0): Printing DDC gathered Modeline (HowTos)
