We have no problem using EVO with the latest 260.19.29 drivers downloaded and installed from nvidia.com.  However, we are unable to view video when using nvidia-x11-drv from sl-contrib or nvidia-graphics260.19.21 from atrpms.  In all cases, xorg.conf is essentially unchanged.

Looks like a DRI/GLX issue at first glance.  I've had very good luck 
with the ELrepo packages:
kmod-nvidia, nvidia-x11-drv combination.  Maybe you are missing the 
kernel module in the first instance.
