Well, I made that harder than it had to be. Instead of installing VNC stuff, I could have just looked in the System Menu, for the “Remote Desktop” option under “Preferences”. (By the way, I’m using it now to verify the wording of everything.)
Then I just use a VNC Viewer, and there we go, I’m seeing and using my Ubuntu desktop from my Win XP laptop. Of course, quality’s a little low, but I think that’s b/c my wireless signal is weak this far from my router. I need to get the ethernet run and set back up, and this will give me the motivation to do that. I’ll report on how it looks after that.
Also, I found “ALE”, the Atlanta Linux Enthusiasts. Lucky me, there are other geeks around!
