Oh? Setting DISPLAY to :0 in the ssh session ought to do the trick.
Maybe also check the setting of $XAUTHORITY. If you set both DISPLAY
and XAUTHORITY in the ssh session to the same values they have in a
regular login session, X apps shouldn't see any difference.

gdb can attach to a running process, so you could also try running the
app locally, and then running gdb via ssh.
A couple of months in the laboratory can
frequently save a couple of hours in the library.
