I did some research on google and found this to be the best answer:
[code]
$ su -
# xauth merge ~cis192/.Xauthority
# export DISPLAY=:0.0
# vmare-toolbox # example X command
[/code]
*EDIT* You might want to put this in the .bashrc file for root.
That worked for me.
This also works:
[code]
$ sudo vmware-toolbox
[/code]
