export DISPLAY=":0.0" should help. But it's probably not a good
idea to do a xhost + as this allows anyone to make connections
to your X server (AFAIK this can also be used to spy out what
you're typing). Better use xhost +localhost so that only local
users can connect or _even better_ don't use xhost at all but
xauth instead (see the Security-HOWTO, man Xsecurity, man
xauth).

Ciao,
        Stefan
