[ale] Remote X - $ xhost: unable to open display ""

[da Black Baron]

A good work-around I use is to simply start a gnome panel (panel & on
the command line), which lets me run a local WM and access all the
programs on the remote box via the panel.  You can color-code it with
the panel preferences if you want to keep things from becoming
confusing... :-)
