Description of problem:
After PreUpgrade Fedora doesn't see my HDMI or I am not able to use it properly.
Version-Release number of selected component (if applicable):
xrandr program version 1.3.5
Server reports RandR version 1.3
Steps to Reproduce:
From VGA at boot
2.use in any way the DVI output -why doesn't it call HDMI anymore-
From HDMI at boot:
2.Change resolution (1280x1024->1360x768 p.e)
Functioning HDMI output
As per IRC discussion, that's with the default radeon/ati driver, not the obsolete radeonhd.
I've reinstalled ati drivers and rebooted and now everything works for me.
