Hi all,

My box uses a Mandriva 2007. I successfully managed to make 3D
acceleration work with my radeon 9600 (fglrx proprietary driver, see
output below).

Then i try "drak3d" to enable XGL and compiz stuff. This change breaks
3D acceleration bu disabling DRI ! How rude !

This is output from some commands before and after enabling XGL :

$ lspci
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AP [Radeon
9600]

$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 Generic
OpenGL version string: 2.0.6011 (8.28.8)

$ glxinfo | egrep "rendering|OpenGL"
direct rendering: Yes
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 Generic
OpenGL version string: 2.0.6011 (8.28.8)
OpenGL extensions:

with xgl/compiz enabled :

$ glxinfo | egrep "rendering|OpenGL"
Xlib: extension "XFree86-DRI" missing on display ":93.0".
direct rendering: No
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 Generic
OpenGL version string: 1.2 (2.0.6011 (8.28.8))
OpenGL extensions:

I ve notice this in Xorg log, don t if it matters :
(EE) AIGLX error: dlsym for __driCreateNewScreen_20050727 failed
(/usr/lib/dri/fglrx_dri.so: undefined symbol: __driCreateNewScreen_20050727)
(EE) AIGLX: reverting to software rendering

I did some googling and i ve tested several hacks (disable composite,
dri 0666 and so on).

Some xgl guru in the place ?

Thanx

This isn't a solution but you may wish to skip the Compiz stuff and try
Beryl instead. I didn't mess with Compiz much, but it seemed that I was
stuck with the same ugly theme. Beryl has many cool themes. I got the
rpms via urpmi at SoS in the contrib/backports section.

good to see i m not alone !

i gave a try to beryl, installed the rpms mentionned but no hope.
my fglrx and xgl don t want to work together. X keeps to tell me :

(EE) AIGLX error: dlsym for __driCreateNewScreen_20050727 failed
(/usr/lib/dri/fglrx_dri.so: undefined symbol: __driCreateNewScreen_20050727)
(EE) AIGLX: reverting to software rendering

do you know if Xorg driver (r300 ?) could give a difference ?

other thing i ve noticed. beryl/compiz both need "composite" (don t know
what it is). if i try to enable that extension, it then shut down DRI.
is it an expected behaviour !?

see first line below :

(II) fglrx(0): Composite extension enabled, disabling direct rendering
(WW) fglrx(0): ***********************************************
(WW) fglrx(0): * DRI initialization failed! *
(WW) fglrx(0): * (maybe driver kernel module missing or bad) *
(WW) fglrx(0): * 2D acceleraton available (MMIO) *
(WW) fglrx(0): * no 3D acceleration available *
(WW) fglrx(0): ********************************************* *

You need to turn the composite extension off. fglrx implements its own
wackiness.
