You just may need to install mesa-utils. To do it, run these commands:
Hope it helps. Let us know how it goes.
sudo apt-get update
sudo apt-get install mesa-utils
: Your card, as most cards, support 2 mayor graphic libraries: DirectX and OpenGL.Yours supports up to DirectX 9 and OpenGL 1.4 (read about it here
). Team Fortress 2 most certainly uses DirectX in Windows. Unfortunately due to the fact that Ubuntu/Linux only supports OpenGL, and that your card only offers support for an old version of OpenGL, you may not going to have complete hardware acceleration.
'mesa-utils' may solve the OpenGL dependencies, but I'm afraid is going to be software emulation. i.e., slower that Windows.
