[rescue] SunOS 4.1.3 X-Windows client to modern Linux System, How?

[Stephen Conley]

Ah man, it's been too long for me :)  This is bringing the memories back.

You're right about it not being fast.  I used to have an E450 / Ultra
Enterprise 2 pair that I did a lot of X over network with.  I remember
specificatlly turning *off* X11Forwarding on SSH because of how slow it was
(and back in those days, it was much simpler to do X over network ... xhost
+, set DISPLAY, and away you go ... :) It was all set up out of the box).
