I have a problem with Valve's Steam on Ubuntu 14.04. Whenever I try to start steam I get an error "OpenGL GLX extension not supported by display".

OpenGL GLX extension not supported by displayAssert( Assertion Failed: Fatal Error: OpenGL GLX extension not supported by display ):Main.cpp:307

glxinfo is giving me

Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
...and so on...

Also, when I open sysinfo->NVIDIA->OpenGL/GLX Information it says:

Failed to query the GLX server vendor.

I have a NVIDIA Quadro K2100M, Driverversion: 346.46

You probably trying to use NVidia driver on mobile platform with Optimus support. Check if these packages are installed, and, if not, try to install them. mesa-dri xf86-video-intel bumblebee
