"the composite extension is not available"

[Afkpuz]

So long story short, I downgraded from hardy back to gutsy. Well, I've ran gutsy before and followed the same steps I always took to get desktop effects working. Install restricted driver, than enable effects. Used to work in the past on clean installs, but not this one. When I try to enable effects, I get the message "the composite extension is not available".


How to fix? why did it decide to do this on this installation when I've done it on a dozen installs without getting this problem?

I'm not 100% on this, but it seems like Xorg doesn't have the Composite extension enabled. Edit your /etc/X11/xorg.conf file and append the following to it.


Section "Extensions"
Option "Composite" "Enable"
EndSection

Restart GDM when done.

sudo /etc/init.d/gdm restart
