That looks like a nice site ... assuming it covers the info you're searching for.
Completely agree with the outdated comment and I searched for a long time before I found a reliable source. You did use Ubuntu 12.04 LTS desk top version , right ?
That's what I started out with before switching to Mint 13.
As of your last effort , are the vid drivers the main issue ? If so, what brand is the card ? I mean verbatim .
Yeah, if I could backtrack on the video driver stuff, I'd be back to a stable, working system. Albeit, not able to power the projector. It's a NVidia GeForce 6200TC (Turbo Cache) card which takes the v173 legacy drivers. I ran into all sorts of trouble with Nouveau supposedly interfering and nvidia-xconfig holding settings but not recognizing them, no X Server running, programs no longer functioning as a result of all that, etc.
One thing I found to be a real stress reliever with Linux is the ability to set it up on a test machine and then muck it up to your hearts content and LEARN . After all , it is free ! If you mess it up , you can reinstall till you turn blue and quite frankly, it installs very quick and the process is easier to me than Windows . Most people who have problems with Linux are die hard Windows users like u and me . It is a "frame of mind" and you need to loose the Windows wipes my butt for me thought process when dealing with Linux .
That's why I used the HTPC build as a Linux test bed.
I've worked with Unix for years for web hosting, but I can never get over how user unfriendly the platform is in general. I think even the most ardent Linux developers have fully embraced the idea that it's really all about the GUI if you want wide-spread appeal. That's getting off-topic, though...
