2014-02-04 01:34:26 -0500 Pergunta comentada Can't load proprietary nvidia driver (fails to initialize GLX extension).

Thanks for help I already figured it out. Unfortunately, my BIOS doesn't support disabling either of the GPUs.

The issue was that I had to explicitly specify nvidia GPU providing bus ID:

Section "Device"
       Identifier   "Videocard1"
       Driver       "nvidia"
       BusID       "PCI:1:0:0"        
EndSection

But in the end, I had to install bumblebee.

I've tried to install nvidia's proprietary drivers from rpm fusion recently but with no luck. Fortunately my system reached graphical environment. But I have found this in logs of X server:

[    39.807] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

Which resulted into:

$ glxinfo

This is pretty strange, because there is an information about successfully loaded nvidia driver several lines above in xorg's log:

[    37.874] (II) "glx" will be loaded by default.
[    37.874] (WW) "xwayland" is not to be loaded by default. Skipping.

[    39.314] Loading extension GLX

I had to remove xorg.conf provided by xorg-x11-drv-nvidia because I couldn't reach graphics (it said "no screens found"). So now I don't have any xorg.conf and there is just 99-nvidia.conf in /etc/X11/xorg.conf.d/ which loads nvidia X driver I presume.

(this was happening on 3.12.5 and 3.12.7 kernel)

Did anyone have similar issue?

I've found this extension ( extensions.gnome.org/extension/358/activities-configurator/ ) pretty helpful. Then you can use icons from:
