Created attachment 385630 [details] /var/log/Xorg.0.log.bak Description of problem: When trying to log in with dual screens X crashes. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.9.1-1.fc12.x86_64 How reproducible: Always. Started when I updated my system today. Steps to Reproduce: 1. Boot with external screen attached 2. Log in 3. Actual results: X crashes and drops me back to login screen Expected results: Normal login Additional info: I can log in with one screen and then attach the other one. Error messages in the Xorg.0.log.bak file seem to indicate a driver problem. This is on a HP EliteBook 2530p laptop with an external Samsung SyncMaster 244T hooked up to the docking station. This setup has worked fine since I first installed Fedora 10 on it.

Hello. I'm havig the very same problem here. When I start X and login with external monitor plugged in, X crashes and starts anew - I get back to the login screen. Happens always. I have notebook with intel 945GM chip and 1920x1080 external monitor. I attached my Xorg.log. BTW sorry for the double-post.
I *think* the problem went away for a while, but it was definitely back today. Will test again tomorrow after todays large bunch of updates.
I have a very similar problem, using the same xorg-x11-drv-intel version, but for 32 bit, on a core i5 with Intel GMA HD. The monitor can handle up to 1920x1200. When the external monitor is conntect before or during boot, the login screen never appears and the system apparentely freezes before I can log in. (In addition, the external monitor cannot be activated even when plugged in after log-in. xrandr then causes a total freeze of the system, as reported in Bug 608954.)
I have since upgraded to F13. F13 had its own display quirks, but they soon went away. I now have no problems with dual screens. Sadly I cannot do any more testing on F12. On F13 I can now boot with 1 or 2 screens, move my laptop into or out of the docking station while powered on or while suspended. It all seems to work. At the moment I am running xorg-x11-drv-intel-2.11.0-4.fc13.x86_64
