I can confirm this bug.
Everything was running well till I upgraded xserver-xgl.
Now, XGL is started but without any acceleration.
>From 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
(II) Loading local sub module "GLcore"
(II) LoadModule: "GLcore"
So AIGLX is started (it shouldn't). Note, I'm using the same xorg.conf
as in my other partition with Feisty. There, XGL, fglrx, and compiz work
without issues.
I tried to modify my xorg.conf to add "AIGLX" "off".. (I used
"Composite" "0"). Doesn't work yet, but I saw in the logs that AIGLX
wasn't started.
I tried also to downgrade to the previous version... no can do.
** Changed in: xserver-xgl (Ubuntu)
Status: New => Confirmed
