Hi kayjay
The command I gave in reply #3 should have returned something.
I can think of three possibilities here:
1. Xorg is not installed.
2. You mis-typed the command. If it responded with just a command prompt, you typed it correctly.
If it responded with file not found or any other message you typed it incorrectly.
3. Your tce/optional directory is not mounted, though that sounds unlikely.
