I'm sure you'll get a bunch of responses, but in general, just plain X
communication over TCP is frowned upon as a security risk. Therefore,
many distributions disable this. Check /etc/X11/gdm/gdm.conf in the
security section, DisallowTCP setting.

The better way to do this is to enable X11 forwarding with SSH, and then
everything will work as the same user. If you change users, you have to
handle xauthority settings appropriately.
