The problem is that the user you're changing to does not have
permissions to write to your Xserver socket.
I'm not sure of the "best" way to fix this, but using xhost(1) should work.

user at host $ xhost +otheruser
user at host $ su otheruser
etc...

I cannot verifiy that this works as I am running headless at the moment.

Hope this helps.
