I have different, much older Radeon. Seems that support for some Radeon
cards isn't stable with current kernels. Some cards seems to work just
fine, with others kernel is crashing all the time. Because of that DRI
(needed for HW acceleration) is disabled if you have Radeon card. You
may try enabling it and checking if things work for you (if your
machines starts crashing or misbehaving, just disable it). Mine happens
to work just fine, and even on my old Radeon enabling DRI made huge
difference.
Things to check:
/etc/X11/xorg.conf. In the Device section (near the end of file), does
it have a line that reads:
Option "DRI"
If not add it. Mine looks something like this (you'll have at least
BoardName line different, and my best guess without checking docs is
that 9000 uses same driver as 7500, if not Driver line will be different
too):
Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "Videocard vendor"
BoardName "ATI Radeon 7500"
Option "DRI"
EndSection
After you save the file, restart X server. The far easiest way is
pressing ctrl-alt-backspace. Be warned that this will kill all GUI
applications running, so make sure you exit from everything.
Once X server restarts and you login again, check /var/log/Xorg.0.log.
Somewhere inthere you should find this four lines (they do not appear
one after another in log file, you'll have to search for each separately):
(II) Loading extension XFree86-DRI
(II) LoadModule: "radeon"
(**) RADEON(0): Option "DRI"
(II) RADEON(0): [DRI] installation complete
Also, /sbin/lsmod should show radeon kernel module loaded.
