I've managed to install vnc4server as well as VNC into it (and change the annoying issue where pressing D would minimize all windows) however when I type unity into the terminal it gives me:

Couldn't find a perfect decorator match; trying all decorators
Starting unity-window-decorator
Setting Update "run_command_terminal_key"
The program 'unity-window-decorator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 400 error_code 2 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

It it possible to solve this issue on a VPS?

Because of the way a VPS operates it is likely highly improbable that you can run Unity via VNC on a Linode VPS. While Linode does use Xen for it's virtualization - I don't think they abstract the GPU and video card details to the VPS. I of course can't confirm this and you'll need to confirm with Linode support.

The only provider that I know of which as GPU's abstracted is the AWS EC2 Cluster GPU Instances though that can be expensive to run.

Since the endgoal is to get unity to launch and let me remote into it, do you think it's possible to achieve this at all on a VPS? If so, could you point me in the right direction? –  Kit Sunde Jul 16 '11 at 10:10
    
@Kit I've updated my post –  Marco Ceppi Jul 16 '11 at 12:11
