Most likely KDE is running its own composite manager effects (using kompmgr), and Beryl therefore can’t run. To disable KDE’s window effects, open up the control center and disable the translucency effects:
K Menu -> Configure Desktop (Personal Settings). Then go to Desktop -> Window Behaviour.
Go to the last tab, “Translucency”, and uncheck the “Use Translucency/shadows” box. Now you can fire up beryl-manager again, and everything should run just fine.
Note: If the above doesn’t work, you may need to add the line
Option "Composite" "0"
to the Extensions area of your /etc/X11/xorg.conf. So far, this option must be present if you are using the fglrx driver (Tested on ATI Radeon 9600)
