Add the below to /etc/X11/xorg.conf, at the end of the file should work.

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

You might have to add the below to the device section in your xorg.conf file too. On my desktop I didn’t have to, but I did on my laptop, not sure if I really needed to.

Option "AllowGLXWithComposite" "True"
Option "AddARGBGLXVisuals" "True"
