Did you use new enough drm? Get dkms from
and then run
and so on.Adaptor #0: "RadeonHD Textured Video"
rv770, debian lenny, dri loads, aiglx (obviously) not, latest drm modules up and running
the funny thing is: radeon 6.12.2 does give tear-free video but is enervingly sluggish after i opened 4 to 5 windows (mostly firefox). then scrolling is slow and i see every window being drawn.
radeonhd works fine regarding speed, maybe because it doesn't give tear-free playback
currently running radeonhd git, about 2 hours old, problem is lack of tear-free video playback.

or do you think it's easier to fix the slowlyness of radeon? i could post that log, too.
They should perform the same as they use the same code with the exception of the Xv tearing stuff. Are you sure EXA is enabled properly in both cases?
Strange, I do get tear-free video playback with both radeon and radeonhd on my HD 3200.
The only difference I notice between these drivers is that with radeonhd I can rotate the screen in all directions with the gnome display preferences, with radeon I only get the choice between 'normal' and 'Upside Down'.
I updated the script a little bit to fix a build problem, before there was a nv module too which could be build, had to remove that for updated git. Seems somebody merged it again. Everytime you rerun it you get a new snapshot of course.
anyway i just used your new script, even rebooted and still tearing in vlc and mplayer using xv, regardless of any other common setting like framedropping.
will try radeon with the new drm...
PS: where should i donate to for the joy of finally having open source video drivers? chipset, cpu and gpu are already AMD

xorg takes up 80% of the cpu while simply scrolling down this web-page...i think i remember seeing 40% with radeonhd but not higher. dual-core with 2,8ghz.
BUT my cpu is constantly running at 100% by two processes with nice 19. and if i stop them, the sluggish moving of windows disappears, but i'm still seeing the window border drawn on the background windows many times, at least on the non-qt windows, qt windows just have little glitches. it looks like a cascade of window borders which disappears after 2 seconds.

um...and sorry for me taking over this thread.
