The ncurses mode of aptitude says Xephyr is a X server that can be
executed inside another X server, more or less like Xnest (or xming,
for people like me that had to work on a windows station but wanted to
keep a nice wm embedded on personal hardware ;)).

I can not really explain how this works, but in short you could
consider a remote system providing the performances stuff (hard disk
space, strong CPU, tons or RAM...) and opening the X session on local
systems.
I think it might fix your problem because basically, su-programs
(probably PAM modules, in fact) do some security related checks to
avoid passwords to be sniffed by a client on another computer: which is
what I would expect a ssh -Y gksudo do.

If my explanation is not clear (and I'm certain of it), it's because I
don't really master that side of systems, sorry for that :)
