I have a problem with my Steam-Installation on Linux Mint 16. I can run some games (like "Starbound") which obviously use OpenGL-Rendering and they run just fine
but many other games also using OpenGL (like "Team Fortress 2" or "Dota 2") dont start. When I try to launch them I get the following error: "Could not find required OpenGL entry point 'glGetError'! Either your video card is unsupported, or your OpenGL driver needs to be updated."
I use a Nvidia Graphicscard (not a High-End Model) with the proprietary driver for Nvidia cards (not the most up-to-date one, Nvidia recommends an older one).
I appreciate your help ,
