I installed beryl on FC6 and followed the instruction for nvidia graphics.... it worked when I first fire up beryl-manager but somehow it does not work any more... it's like beryl does not exist.... I have the diamond sharped beryl manager on my tool bar but nothing seems to work.

I tried to yum remove beryl and yum install beryl but no change.... any help much appreciated. Here's my xorg.conf:
