Odds are:
/var/log/Xorg.0.log:[ 11.590] (EE) Failed to initialize GLX extension
(Compatible NVIDIA X driver not found)
is the cause of your error.
I'd suggest the ELrepo Nvidia modules:
yum -y install yum-conf-elrepo
yum -y install nvidia-detect
yum install $(nvidia-detect)
May fix your issue, or it may not......
