This is where you should try -Y instead of -X.

Emacs is one of the programs that is known to have issues with the
"untrusted X" setup.

When you do this, you are bypassing the SSH X tunnel that has been set up.
 Either drop the "-display" argument, or make it point to the tunnel that
SSH set up.  By default I believe the tunneled display is localhost:10,
but normally SSH does the right thing and sets the DISPLAY variable
correctly.
