Fixing Compiz Fusion on ATI Radeon Mobility 9800 Under Ubuntu Hardy (8.04)

**** OK, this works–but it’s not feasible. I found xserver-xgl to be VERY slow and had screen rendering issues. ****

Take this for what it’s worth–and that does not seem to be much.

When I originally installed Ubuntu Hardy on my HP Pavillion zt3000 laptop Compiz worked perfectly. Much to my dismay, after I re-installed, Compiz Fusion would not re-enable, even though I had the restricted drivers installed and enabled. (Selecting System -> Preferences -> Appearance -> Visual Effects -> Extra returned a “Desktop effects could not be enabled” error.)

I tried running “compiz” from the command line and one line of the output caught my eye:

checking for xgl not present

That gave me enough search terms to search on Google and hit paydirt on UbuntuForums.

The solution was simple: Go to System -> Administration -> Synaptics Package Manager and install “xserver-xgl.”

After I logged back out and back in, I enabled Compiz ( System -> Preferences -> Appearance -> Visual Effects -> Extra) and everything worked.
