Re: x apps cant start from bash

[Rupert Brooks <rbrook at cim dot mcgill dot ca>]

Solved my own problem; sorry to bother y'all

FTR, the solution is that 
a) if the DISPLAY variable in bash is set without export, then when SSH
starts up its not noticed, and then SSH does not notice where to send
the X11 stream

b) you have to set and export the display variable, it is neither set
automatically, nor does ssh have a default.

I'm a tcsh user, so didnt realize that necessity under bash.

This seems to be covered in the SSH notes message, sorry I didn't see that
before.
