Bug Description
== SRU Justification ==
A regression was introduced in the v3.0.3 stable update. User has a HD5770 card with 3 screens connected (1 monitor to DisplaPort-0, 1 monitor to the DVI-0, and a TV to the HDMI-0), the screen connected to display port immediately goes black and reports "no signal". To wake the screen again, they had to issue the command xset dpms force suspend" which then wakes the screen connected to the display port. The same thing also happens when turning the tv off.
== Fix ==
http://
== Test Case ==
With the fix applied, turn tv on and off and confirm it does not interfere with my other connected displays.
==========
The problem is this:
I have an HD5770 card with 3 screens connected, 1 monitor to DisplaPort-0 and 1
monitor to the DVI-0 and a TV to the HDMI-0
When I turn my tv on the screen connected to displayport immidiately goes black
and it says "no signal". To wake this screen again i need to issue the command
"xset dpms force suspend" This will wake the screen connected to the
displayport. The same thing also happens when I turn the tv off again.
How it should work and has worked before:
I should be able to turn my tv on and off without it interfering with my other
screens.
I have pinned this regression down to happen in the kernel 3.0.3 found here
http://
But it is alright in the kernel 3.0.2 found here
http://
This is the changes made between 3.0.2 and 3.0.3 that i think has something to
do with my problem.

Hi Gustav,
Thanks for pinning down the version where this regression was introduced. Give me a bit and I"ll try and get you a test kernel with those radeon patches reverted to see if this helps. Thanks.
