Local security, disabling of.

One different method:

$ ssh -Y root@localhost
# gparted &
#

The '-Y' option enables X11 forwarding. (This of course requires sshd.)

You can probably justify 'xhost +' if this is one of those
I'm-the-only-user machines. Thank Ghu, remote network access to the X
server is no longer enabled by default on Linux hosts. (The right way
to do remote X11, IMO, is via 'ssh -Y user@???', thereby
forwarding X11 across the authenticated ssh tunnel.)

One can argue that you should use 'ssh -Y' even locally so you get out
of the habit of using 'xhost +'. I won't argue that, but will just put
it out there.
