Have tried both letting the config take care of it and using the
options on the command line. My normal way is a desktop icon
launching a "gnome-terminal -e '/usr/bin/ssh -X jon@butch' -t butch".
But as noted, I've been entering commands from the shell as well.

My primary test command was xclock. If DISPLAY is unset, it prints an
error immediately (Can't open display: ). With DISPLAY set, it never
displays, outputs any messages, nor returns. I have to kill it.
As suggested, I tried xterm. With no DISPLAY set I get "xterm Xt error:
Can't open display:". With it DISPLAY set to "localhost:10.0" I get the
same error with the value of $DISPLAY appended to the message. If I set
DISPLAY to point directly to mums screen (mums.jgcomp.com:0.0, mums:0.0,
or <mums IP_ADDR>:0.0) then xterm outputs nothing and doesn't return.
