[comp.windows.x] How to protect my DISPLAY?

haozhou@acsu.buffalo.edu (hao zhou) (03/21/90)

since X allows you to access any terminal or workstation by setting  
DISPLAY to that station, it  is pretty easy for you to be disturbed
by somebody's xclient if he accidentally sets his DISPLAY to your 
station's IP. 

what i wonder is if there is any way to protect yourself and keep from 
something being displayed on your screen from somebody else.
( assume that other people can access my host).

	thanks in advance
