Ok so I managed to get Beryl and my nVidia card working with the latest and great version of Beryl....
Here is how!
1) First I added the Linva.org yum to my system
open a terminal and as root run this command:
# rpm -ihv
http://rpm.livna.org/livna-release-7.rpm
2) then in the same terminal run this command:
# yum install kmod-nvidia
3) restart your system
4) try out Beryl....
I didn't have any issues it was that easy. Once I found the right drivers from livna it was no problem.
Hope this helps someone else!
