Consegui configurar a minha GeForce 8600M GS/PCI/SSE2 com ajuda destes topicos:

http://ubuntuforum-br.org/index.php/topic,34838.0.html

Aparentemente tudo funciona normalmente, mas quando executo o comando glxgears o sistema apresenta o seguinte erro:

Error: API mismatch: the NVIDIA kernel module has version 173.14.05,
but this NVIDIA driver component has version 173.14.09.  Please make
sure that the kernel module and all NVIDIA driver components
have the same version.
NVIDIA: Direct rendering failed; attempting indirect rendering.
XIO:  fatal IO error 104 (Connection reset by peer) on X server ":0.0"
      after 41751 requests (40810 known processed) with 0 events remaining.

Alguem saberia como ou porque esse erro ocorre?

Obrigado.
