xgl rendering problem

problem with rendering XGL
I use beryl, fglrx and xorg.conf

# glxinfo
name of display: :0.0
Xlib: extension "XFree86-DRI" missing on display ":0.0".
display: :0 screen: 0
direct rendering: No

I was trying recompile drivers. Wired is that when I first time was
using xgl and beryl rendering worked fine even in XGL. After mayb efew
days something broked.

When I switched on regular X it works fine

I use unstable ati drivers
emerge -pvD ati-drivers

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild UD] app-admin/eselect-1.0.7 [1.0.9] USE="-bash-completion
-doc (-vim-syntax%)" 0 kB
[ebuild UD] x11-drivers/ati-drivers-8.35.5 [8.36.5] USE="acpi qt3" 0 kB

stable works the same, no rendering...

Did you get this fglrxinfo-output after a warm or a cold boot?
fglrxinfo shows "OpenGL vendor string: ATI ..." when DRI is working and
"OpenGL vencor string: Mesa..." when it's not.
Please post your glxinfo-output as well, that is, at least the line
with "direct rendering".
Maybe you experienced your problem with XGL after a cold boot where
your aperture base wasn't set up all right by your BIOS. There are some
bugs @ bugzilla.kernel.org about this.
After a reboot it may be working.

I am facing the same problem, and I think the reason for this can be found in the Xorg.0.log:
(EE) AIGLX error: dlsym for __driCreateNewScreen_20050727 failed (/usr/lib/dri/fglrx_dri.so: undefined symbol: __driCreateNewScreen_20050727)
(EE) AIGLX: reverting to software rendering

so i guess, it will get fix in the next or some future release.
[edit] i get great FPS, something like 4900 when i am running applications like firefox, evolution, etc, but on a lightly loaded system, i get FPS around 6000. It is just this DRI thing that is failing. I am using the ati repository for openSUSE10.2 for the drivers. Have disabled the composite extension in xorg.conf.
I think ill raise a bug in ati/amd bugzilla and see if they have any answers.

I dug around a bit, and saw that there actually is DRI happening, it is just some display problem the fglrx_dri.so module, or something like that, not sure.
Xorg.0.log does show that the server loaded dri, in loading fglrx.
high FPS vouches for that.
Also, i forgot to disable AIGLX in my serverflags, i think it got overwritten when i reconfigured my X.
So, I have some peace in knowing that my card is giving good performance with direct rendering.
