That was it!
Now I've used apt to update 5 packages, and its now installing synaptic
and all its 2nd and 3rd cousins. 112 megs worth. I did ask it to install
xfce, but it couldn't find it. I'll try lxde next, but its entirely too
simple. With xfce I can set up 4 workspaces/windows and the survive a
reboot. You can add them in lxde, but they don't survive a reboot.
Anyway, progress, sorta. I am going to put that command in rc.local just
for S&G. Oh, oh, I had to create that file, does not bode well. But
we'll find out I guess.
Thanks Alan, a bunch. I owe you a cold one. :)
