Olha, aqui em casa bastou eu instalar o pacote nvidia-glx. Para placas antigas baseadas no chip nvidia tu deve usar o nvidia-glx-legacy.
NVIDIA binary XFree86 4.x/X.Org driver
These XFree86 4.x/X.Org binary drivers provide optimized hardware acceleration
of OpenGL applications via a direct-rendering X Server and support the newer
GeForce, nForce and Quadro families of NVIDIA chipsets. AGP, TV-out and
flat panel displays are also supported.
If you have a TNT, TNT2, or older GeForce, you may need the nvidia-glx-legacy
package instead of this one.
