I use MythTV, so the PC outputs on HDMI to the telly. I use a PS3 as well though, and if I swap to that for a while, then back to MythTV, the X output has turned to rubbish. It shows a load of random coloured pixels, and sort of flashes off for a second, then back to the pixels. I'll try and post a video if it helps! The HDMI from this card never used to work at all, but somebody else fixed that. There's detail of my set up and the work done to fix Xorg here ... https://bugs.freedesktop.org/show_bug.cgi?id=49752
A candidate for further infoframe introspection.
http://youtu.be/ch6K66utQGg This is a video of what happens.
The server is running 3.6.6-1.fc16.x86_64 at the moment.
Can you please boot with drm.debug=0xe added to your kernel cmdline, reproduce the issue and the attach the dmesg? Hopefully there's something in the logs ... Also adding Paulo, our residental infoframe expert.

Crap, need to redo that then.
Deleted the bloody video off the phone, will try and do it again. Hardly use the PS3 atm though.
Also, we really need that dmesg with drm.debug=0xe to know what hw your have and what exactly might be wrong. Please also test this patch, it fixed a few other hdmi black screens: https://bugs.freedesktop.org/attachment.cgi?id=71493
http://www.youtube.com/watch?v=RAeL9ipPpJ4&feature=youtu.be I finally uploaded this again!
I should add that I upgraded to Fedora 18 with all updates applied. This then happened again after a session on the PS3 :(
Please attach the dmesg Daniel asked for in comment #4 and again in comment #8. Also, it's not clear to me how you switch between sources. Do you have to swap the cables, or do you have both sources connected and switch inputs on the TV? What if you unplug/replug, does it fix the output?
1. Just swap channels with the AV button on the telly remote. Tried swapping the PS3 and PC onto each others HDMI ports, it didn't help. 2. Not actually tried unplugging and replugging the cable. Will Gnome handle that gracefully?! Will have to try it I suppose! It comes back up if I putty in and kill -9 Xorg!
The dmesg, please.
Likely that this was fixed by: commit 202adf4b9f5957b26a1cb97267d78e0edb319c5e Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Feb 22 00:53:04 2013 +0100 drm/i915: Revert hdmi HDP pin checks
3.8.1-201.fc18 It just did it again. Updating to that kernel. When did the fix go in?
It's in 3.9 and in the process of getting backported through stable kernel releases right now.
