ATI recently released their new driver for Linux, v 8.42.3. It took some work to get Gutsy running properly in Compiz, without XGL, only AIGLX. Here's how...

Re: Gutsy, Xgl and ATI fglrx AND MESA

I too had this problem after applying the 8.42.3 ati driver in gutsy: Mesa took over the rendering. What it came down to, from looking at /var/log/Xorg.0.log, was that the fglrx module was not loading, even tho' it was quite happy installing itself from the binary, and from Envy (which uses the same binary). After googling a bit I did this to fix:

first of all Become su, and do the following preferably outside of an X session, and having no X-sessions running. This is after the driver is installed!!!

1.) lsmod (look for any thing that says ati if exists type rmmod ati)

2.) cd /lib/modules/fglrx/build_mod/

3.) sh make.sh

4.) (not necessary but good to do anyway just in case) modprobe agpgart

5.) cd /lib/modules/fglrx/

6.) sh make_install.sh (Ignore any warnings about kernel taint)

7.) modprobe fglrx && lsmod | grep fglrx

8.) reboot, so that X can restart with it's default modules loaded.

Now I get:

fglrxinfo -display :0

display: :0.0 screen: 0

OpenGL vendor string: ATI Technologies Inc.

OpenGL renderer string: ATI MOBILITY RADEON X600

OpenGL version string: 2.0.6958 Release







Steps: follow the instructions on first page.

But don't reinstal xserver-xgl

I needed to alter /usr/bin/compiz to whitelist the fglrx, and comment out the line blacklisting my graphics card (X600).

Then I make sure composite and AIGLX is enabled in the xorg.conf. My file:

EDIT

After a kernel upgrade you need to do this:

1.) sudo -i

2.) cd /lib/modules/fglrx/build_mod/

3.) sh make.sh

4.) (not necessary but good to do anyway just in case) modprobe agpgart

5.) cd /lib/modules/fglrx/

6.) sh make_install.sh (Ignore any warnings about kernel taint)

7.) modprobe fglrx && lsmod | grep fglrx

8.) reboot, so that X can restart with it's default modules loaded.

After a Compiz upgrade you need to edit the /usr/bin/compiz file to whitelist fglrx again.
