I have a problem with Steam on Ubuntu 14.04. Whenever I try to start steam I get the error message: "OpenGL GLX extension not supported by display".
When I try to start steam via the terminal, I also get this:


Code:

glxinfo is giving me:


Code:
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
