Trouble with getting dri to work using the radeon driver.

Hi,

I am trying to figure out why i can not get direct rendering working
using the radeon driver.
I am now running ubuntu edgy and my graphics card is a X700 mobility
radeon card.

I'll post some info that i have tracked down.
If i set LIBGL_DEBUG to verbose and run glxgears, I get the following output:

----snip---
libGL: XF86DRIGetClientDriverName: 5.2.0 r300 (screen 0)
libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri//r300_dri.so
libGL error: dlopen /usr/X11R6/lib/modules/dri//r300_dri.so failed
(/usr/X11R6/lib/modules/dri//r300_dri.so: cannot open shared object
file: No such file or directory)
libGL error: unable to find driver: r300_dri.so

libGL error: unable to find driver: r300_dri.so
5555 frames in 5.0 seconds = 1110.999 FPS
---snip---

If I run export | grep LIBGL, i notice that the LIBGL_DRIVERS_PATH is
set to the wrong directory. It should be /usr/lib/dri/, but it is set
to /usr/X11R6/lib/modules/dri/.

If I change that to /usr/lib/dri, or create a symlink to point to the
right place, I get another error:

name of display: :0.0

libGL error: unable to find driver: r300_dri.so

libGL error: unable to find driver: r300_dri.so
display: :0  screen: 0
direct rendering: No
...

Does anyone on this list know how to solve this? I think the problem
is some old remains of an fglrx driver, but I have uninstalled all
fglrx related stuff and reinstalled all mesa and open source ati
driver packages.

Regards
Martin
