I used the procedure detailed in the link you cited and I got the resolution I wanted. The only problem is that the desktop is offset to the upper left so that only the lower right corner is visible. I can read the time and date, and connect to a network but that"s all. Even right clicking on the desktop and selecting "open a terminal" does no good since the terminal opens in the area of the desktop that I can't see.
Tried a reinstall and the same thing happened. When the desktop loaded from the CD, the resolution was fine but only the lower right corner was visible. Rebooted in compatibility mode and was locked into low resolution. Tried the patch - ended up with one fourth of a desktop at good resolution.
Even tried to install Ubuntu. Same results.
I think this computer just doesn't like Linux.
 6 hours later. Freespire installs like silk, but I don't care for their desktop, network manager, or download manager. I prefer Mint.
