HOWTO: Remote Desktop with VNC in Ubuntu Edgy/Feisty

Updated, 4 May 2007: Warren helpfully pointed out in the comments a possible fix for the problem with the latest vnc4server. It worked for me in Edgy, and I hope it works with these instructions for Feisty Fawn also.

Ubuntu/Xubuntu Live CDs

I mentioned that I tried running Xubuntu GNU/Linux from a CD (a Live CD, I guess you call this kind of thing). I had been seeing these CDs of the various Ubuntu systems and the exhortation to try them without having to install anything. I was skeptical about how well that would work.

Well, it worked great. I wasn’t even sure if my old machine would boot from a CD, but it started up with no problems. (And with plenty of screen resolutions to choose from, which was nice after my earlier travails.) I didn’t do much other than verify Firefox could get to the Internet and that OO.o Calc …
