Using nvidia-smi should tell you that:

bwood@mybox:~$ nvidia-smi  Mon Oct 29 12:30:02 2012        +------------------------------------------------------+                        | NVIDIA-SMI 3.295.41   Driver Version: 295.41         |                        |-------------------------------+----------------------+----------------------+ | Nb.

On any linux system with the NVIDIA driver installed and loaded into the kernel, you can execute:

cat /proc/driver/nvidia/version 

to get the version of the currently loaded NVIDIA kernel module, for example:

$ cat /proc/driver/nvidia/version  NVRM version: NVIDIA UNIX x86_64 Kernel Module  304.54  Sat Sep 29 00:05:49 PDT 2012 GCC version:  gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
