Created attachment 628813 [details] log from working system Description of problem: After upgrading to kernel-3.6.1-1.fc17.x86_64, xorg no longer works with external monitor on my Dell Latitude D630. The system boots up, boot messages get displayed on both external and internal display, but when I try to disable internal display in KDE, the whole xwin gets stuck. It is possible to login via ssh, but 'shutdown -r now' doesn't work. When I try to boot older kernel, everything works just fine - so I assume it is kernel problem. Version-Release number of selected component (if applicable): works: kernel-3.5.3-1.fc17.x86_64 doesn't work: kernel-3.6.1-1.fc17.x86_64 How reproducible: always Steps to Reproduce: 1. just reboot - xwin login doesn't appear on external monitor while notebook lid is closed as it used to appear. 2. try to disable internal display - xwin freezes 3. Actual results: system freezes Expected results: system disables internal display, moves everything to external one and it is possible to work Additional info: Fedora 17, KDE, external monitor connected via VGA connector.

Can you try again with kernel-3.6.2-4.fc17 ? I believe this is fixed in 3.6.2.
With kernel-3.6.2-4.fc17, the system behaves differently. When I try to disable internal display, BOTH displays go off. After some time, both displays go on again, but this time the system doesn't freeze. When I try to disable internal display again, it works as expected. Non-ideal, but acceptable.
OK, after fiddling with KDE settings I've managed to bring back the old behavior. I am satisfied now and closing this case. Thanks for your help!
