I suppose you are using the nvidia's proprietary code.
If so, i feel something about permissions.

Try to log in as root, and launch vmd there.
If it runs, it is then that your /dev/nvidia0 and /dev/nvidiactrl is no
more readable by normal users.

You can change it by chmod 0666 /dev/nvidia and /dev/nvidiactrl

I suppose you have a cron table that verifies periodically the
permissions (in mdk, for example it is regulated via msec).
