greetings,
I have a HD5450 hooked up to my lcd tv as part of a multiseat setup. every few seconds the feed flickers.
usually I use xbmc to view content but it happens with VBox too.

--- Comment #1 from Alex Deucher agd5f@yahoo.com --- Please attach your xorg log and dmesg output. Does setting radeon.disp_priority=2 on the kernel command line in grub help?

--- Comment #3 from dagg stompdagger1@yahoo.com --- greetings,
sorry it took long to answer, it seems that the time between one flickering to another has got bigger, from one every sec I have now one every few minutes.
this might be related to the fact that I'm running mesa, libdrm and xf86-video-ati from git an update them every week.
anyway, here are dmesg and xorg log (I was sure I attached it but it seems that i didn't).
I'll try now with radeon.disp_priority=2 and report back.

--- Comment #7 from dagg stompdagger1@yahoo.com --- with the patch applied it still flickers, moreover it might have increased the rate of flickering.
not sure if it is relevant but I use a 10 meters cable to connect the tv to the computer

That's a bit much. Could you try with a shorter one to make sure it's not the cable?

nope... tv is too far. anyway, didn't had any issues when I was using the intel gpu.
