I upgraded to Jaunty ant tested this on Jaunty now. Seems to work very
good. No garbling, no slowness. The performance when rotated is not
perfect, but good.

Thanks for that very thorough testing!
While it looks like with EXA there is still room for improvement in
performance, as a general rule it seems the performance has improved
notably. In particular, from your results there are no corner cases
with really bad performance with EXA on Jaunty as

I've performed some test with the Jaunty alpha 3 x64 livecd. I don't
have enough disk space to install it next to Intrepid, but I'll get a
new disk next week.
The default radeon acceleration method changed from 'XAA' (Intrepid) to
'EXA' (Jaunty). The Jaunty xorg logfile has been attached.

I cannot rotate my 1400x1050 display. The graphical tool does not give
me another option than upside down, the command xrandr -o left
rotates the display, but the result is garbled and slow. (see

I have the same problem with :
- Ubuntu 8.10
- ATI RADEON 7500 + xserver-xorg-video-radeon 1:6.9.0
- Monitor Samsung SyncMaster 204B
- 1600x1200 resolution.
I added Virtual 1600 1600 to avoid garbage on screen when I rotate
right, but the display is very slow (about 1 s every time you close or
Your assumptions are correct. The remaining problem is the slowness. It
affects all kinds of rotations and inversion, but I only use left
rotation.

Erdal solved the garbled screen issue by adding 'virtual 1400 1400' to
his xorg.conf (second post). His remaining problem is the slowness.
When I added 'virtual 1920 1920' to my xorg.conf, the left/right option
in the gui became available. That probably also happened to Erdal when
he added
Sounds like the real issue here is that L/R rotation is resulting in
corrupt display when used with xrandr. If that's fixed, then the lack
of the option in the GUI can be examined.
@elc, I would ask you to report your issue as a separate bug; while your
symptoms are similar to Erdal's, they're
