vroeger werkte beryl maar er was een probleem met mijn scherm dat stond te veel naar rechts.
volgens iemand moest ik de resitricted drivers gebruiken, dit gedaan en probleem scherm was opgelost.
Van dan af werkt beryl niet meer.
dit is de fout;
patrick@patrom:~$ beryl-manager
patrick@patrom:~$ Xlib: extension "XFree86-DRI" missing on display ":0.0".
