Hi,

I can confirm the same problem with Catalyst 12.2 and Radeon HD3200. I
have HDMI connection to my TV and after switching the TV off and on the
driver fails to recover the desktop. The applications stay active in the
background. Looks like the driver fails to probe or initiate the
connected output and/or read the EDID data from the connected TV.

Have tried everything possible solution/suggestion I could find for this
problem including disabling DPMS and Composite extension to no avail.

Igor
