Just a small quick note.
If you are using the nvidia proprietary drivers from our openSUSE repos. Take care of the following fact. By default the new drivers didn’t add your user to the video group.
Getting Gnome, kdm, kde, or other application running well you have to add your user to the video group.
YaST User & group management being your kindly Gui friend.
or use usermod
sudo usermod -A video yourusername
Happy 3D acceleration!
