ssh user at 192.168.1.3

(just the regular old ssh command!); then you can start apps on Server
via the terminal window, and they'll show up in windows on Client's X
display.

This section is not working for me. here is what i receive in the terminal
when trying this:

X11 connection rejected because of wrong authentication.
The application '.' lost its connection to the display localhost:10.0;
most likely the X server was shut down or you killed/destroyed
the application.
