William,

Assuming machineA and machineB are both sitting on your desk,
and they have a shared home directory, then

on machineA enter
# allow machineB to throw X connections to machineA
xhost +machineB

# save machineA's xauthorisation data
xauth extract ~/foo.auth $DISPLAY



on machineB enter
# import machineA's xauthorisation data
xauth merge foo.auth ; rm ~/foo.auth

# open new X applications on machine A
export DISPLAY=machineA:0.0

# start the debugger....
gdb ./myApp
run



This should work; xauth can be tricky to get right.
machineB can also be a remote computer logged into via
ssh, but not from machineA.
