Radeon + Xorg + WXGA LCD TV = it works!
I managed to get my IBM Thinkpad T41 Radeon Mobility 9000 running Ubuntu Edgy with X.org 7.1 to display on my Sony Bravia 40″!
I was trying to get this laptop to support 1360×768 at 60Hz without luck. At first, I was unable to have the open source driver to use this mode and frequency. Later I tried binary driver, but seems it doesn’t support Xv, making video playback slow as hell if you want to scale it.
But after some googleing I’ve found a nice example of using various servers layout on top of the open source driver http://mg.pov.lt/xorg.conf. Then I found how to get the correct mode-line using read-edid (get-edid | parse-edid).
Now it is working perfectly, even with MergedFB option (radeon’s own Xinerama implementation), with monitors at different resolutions working together!

ATI has released an updated version of its proprietary driver which solves the problem with Xv:

I must admit I’ve never used the open source driver for radeon, but do you get good 3d acceleration with it? Some versions ago the proprietary driver used to have some problems with xorg on Ubuntu, but now I am pretty happy with it..

I don’t need 3d, I don’t play any games and while I like cool desktops, I don’t like AIGLX that much… I want to have EXA, XRender and Composite working fast… and it won’t happen anytime soon with ati binary drivers.
