Hi,
  This usually means that you've got bad file permissions on
the video card device nodes. Double check that /dev nodes for your
video card have correct permissions, here's an example of what they
would typically look like on a multi-user NVidia-based linux box:

ls -al nv*
crw-rw-rw- 1 root root 195, 0 Apr 18 15:01 nvidia0
crw-rw-rw- 1 root root 195, 1 Apr 18 15:01 nvidia1
crw-rw-rw- 1 root root 195, 2 Apr 18 15:01 nvidia2
crw-rw-rw- 1 root root 195, 3 Apr 18 15:01 nvidia3
crw-rw-rw- 1 root root 195, 4 Apr 18 15:01 nvidia4
crw-rw-rw- 1 root root 195, 5 Apr 18 15:01 nvidia5
crw-rw-rw- 1 root root 195, 6 Apr 18 15:01 nvidia6
crw-rw-rw- 1 root root 195, 7 Apr 18 15:01 nvidia7
crw-rw-rw- 1 root root 195, 255 Apr 18 15:01 nvidiactl

You may also want to double-check that you have the file permissions
on the VMD installation directory set correctly.
