Hello CentOS-Community,
I have to maintain a server that should be useable with VNC and some software requires to run VirtualGL.
Also a nvidia graphic card is installed.
After downloading and installing the nvidia driver from nvidias homepage and modifying
the xorg.conf as mentioned on the virtualgL-homepage,
I am not able to restart lightdm anymore.
Lightdm should be running, otherwise it is not possible
to run virtualgl in an appropriate way.
I had the same/similar issues on three different servers with three different nvidia graphic cards.
Any help is appreciated.
Best Regards,
Felix Kölzow
