Description of problem: I can no longer select my external monitor (Hardware is a Thinkpad T400 w/ docking station, external monitor is plugged into the DVI. xrandr shows HDMI1+2 as disconnected. With the previous kernel (3.8.2-206) it works, the monitor is available as HDMI2. Version-Release number of selected component (if applicable): kernel-3.8.3-201.fc18 How reproducible: Boot. Run xrandr -q. Additional info: Regression from kernel-3.8.2-206 which works. If I can provide any additional info, please ask.
I am using (Name: kernel, Arch: x86_64, Version: 3.8.2, Release: 206.fc18) because I cannot get my H.D.M.I. connection to work for an external monitor (L.E.D. TV) with (Name: kernel, Arch: x86_64, Version: 3.8.3, Release: 201.fc18). It would recognize the display in gnome-system-settings, but wouldn't ever actual display to it. Also, when I would disconnect the cord, it would leave a 0" monitor as the secondary monitor. I am using a Dell Studio 1555 through H.D.M.I.
I have a similar problem which prompted me to find this bug. I'm on a Dell Latitude E4300 and my external monitor which is plugged into my docking station via DVI no longer worked after the update. I'm running Fedora 18 and choosing Kernel 3.8.2-206.fc18.x86_64 from boot up fixed the issue, 3.8.2-206.fc18.x86_64 has the issue.
what graphics driver(s) are these systems running ?

This is fixed for me in Kernel 3.8.3-203.fc18.x86_64 I'm guessing the bug was located and fixed as this was out shortly after 3-201 There was a mistake in my comment above, I meant that 3.8.3-201.fc18.x86_64 has the issue.
Looks like resolution was this related to the fix for this bug: https://bugzilla.redhat.com/show_bug.cgi?id=922304 2013-03-18 - Justin M. Forbes - Revert rc6 ilk changes from 3.8.3 stable (rhbz 922304)
