not realy a stupid question. before doing a "su" try a "xhost
+your_machine_name"
after that, things should work.

btw. if you are networked and want to start i.e. xclock on
"mothers_machine" do a xhost +mothers_machine, after telnetting to it
try export "export DISPLAY=your_machine_name:0.0". after that "xclock
&". Program running on mothers_machine, display on yours.

have fun!!
