AIGLX error

[Renato Budinich]

Hello, i'm using the radeon open souce driver for ati cards and Ubuntu
Jaunty 9.04. I would like to run compiz, but i get this error:

renato at renato-laptop:~$ compiz --replace

I was told on the compiz forums that the errors in in my Xorg.0.log
could be the cause. This is what i have:


$ grep EE /var/log/Xorg.0.log -C 10
