Hi.

I have 2 graphic cards on my laptop:
1. Nvidia GeForce GT 740M.
2. Intel graphic card.

The Intel's card is working well.
For Nvidia's card, I added the official Nvidia repository from YaST2, and
installed the "x11-video-nvidiaG03" package (beside other dependencies) from
it, actually I am not the one who chose this package, it's the YaST2' "Install
Recommended Packages" option which did.

After installation and after reboot, When I try to run a game (like teeworlds),
I got this:

[15-11-12 10:13:13][gfx]: unable to set video mode: Couldn't find matching GLX
visual
[15-11-12 10:13:13][gfx]: out of ideas. failed to init graphics
[15-11-12 10:13:13][client]: couldn't init graphics

And I can't run the game.

When I try to run Steam, I got: "OpenGL GLX extension not supported by
display". And Steam go closed.

When I try to run the "glxgears" command, I got:

Xlib:  extension "GLX" missing on display ":0".
Error: couldn't get an RGB, Double-buffered visual

Any fix?

Reproducible: Always

Steps to Reproduce:
1. Install the closed Nvidia driver from its official repository.
2. Reboot the computer.
3. Try to run "glxgears" command or steam or any game to see the problem.
Actual Results:  
Games, Steam and glxgears command can not be run.

Expected Results:  
The above software should have worked normally with the closed driver, or even
better.
