Oh, I see what you did here... Sorry for my earlier responses.  I've
somehow failed at reading comprehension. (just don't call me Karl, k?)

You do not need to, nor should you, run startx on the remote computer.
For any X application to work, including gedit, you need to have
"Xserver" running on the computer that will display the application.
This is confusing, as it flips terminology around.  Xserver needs to run
on the "Client" computer, not the Server computer.. got it?  The
application that runs on the application server, like gedit, is called a
client application..... (don't look at me, this terminology was invented
by egg heads in the 70's.)




So, for example


Application                   Thin Client
Server
  |                                |
Headless                     Monitor + Keyboard

  |                                |
X Client App.                  Xserver Display
(ex. gedit)

As for why gksu didn't work until you tried to run startx is a bit of a
mystery, it is probably a gksu specific problem.  Try sudo gedit.
