I have some issues with the tv-out of an HD2600XT (RV630)
I tried Ubuntu 9.04 with xorg-edgers and a .33 and .34 kernel.
I also tried a 10.04 stock live cd. Results were exactly the same.
I'm trying to use an 7" portable dvd-player (a ViewFun MP-72. It is also sold as Mustek, and the same chipset is found in other dvd-players as well) as a 2nd monitor. It worked with fglrx...
I also have an 19" LCD monitor connected with a DVI-VGA adapter.
I can boot the machine in two ways. With and without the dvd player connected.
Without the player connected everything works fine. The login screen and desktop work at 1440*900 and there's proper acceleration. Everithing works as it should. Kudo's to whoever did make this happen! (ati/amd employers excluded) Finally! (I own this card since sept. 2007, and I never had proper drivers until now...)
But I could also pulg in the dvd player. I can see the bios messages and grub menu on both screens. I might even see (part of) usplash. Then the dvd player turns blue, like it is recieving no signal. The main monitor displays the login screen at a distorted 1024*768.
When I login my monitor switches to 1440*900, but it shows an out-of-range error. The image looks a bit noisy, and the refresh rate looks low, like 25Hz. Especially mouse movement is not fluid.
Strory continus tomorrow, with drm.debug and xrandr output...

That's with the dvd player connected, but still disabled.
xrands shows http://pastebin.com/5vD3TLEu
It is properly detected, so I can enable it. The out-of-range thing stops, and things work great on my main monitor. GNOME expands the desktop to the dvd-player, but there's still no signal. Blue, with nothing on it.
xrandr now shows http://pastebin.com/tm5TPgFB
The funniest thing is it detects an "tv" when I connect the composite wire to the ground wire, (using a screwdriver). So it doesn't really detect anything... But that's a limitation of the composite signal.
I booted the system with drm.debug=14, and these are the results:
without dvd player: http://pastebin.com/f4ftQBDN
with dvd player: http://pastebin.com/AwzLGwcx
I ran dmesg at the gdm login screen over ssh.
My setup looks like this: http://www.youtube.com/watch?v=NfZvJ-WTTXg
Ignore the laptop. I shot the video with fglrx in a good mood. That's very rare...
I just compiled a fresh kernel from git, as decribed here: http://wiki.x.org/wiki/radeonBuildHowTo#Bleedingedgecodefromdevelopmentbranch
Same results as before...
