several things can go wrong here: With the change of user, the $DISPLAY must be transfered too. This sometimes goes right, most times goes wrong. Most apps default to :0.0 hence you will not notice at the local console. you can avoid this by `su -` (or `su - user`) and at the prompt verify (and update0 the setting of $DISPLAY. Then, the new user might not have rights at the used display. You can manipulate that with `xhost`, see `man xhost` for details. `xhost +` will remove all security to avoid this problem at all. btw: root cannot use its power privileges at this level, there is no super-user defined inside X11.
