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.

Comment 6 Lee Ball 2013-03-20 08:47:47 UTC
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.
