Installing Ubuntu is a straight forward process, in the other hand setting the resolution might become a "pain in the neck". For many users (NOT USERS W/ Intel Chipset 8x-9x; see below) changing the resolution of the screen should be as simple as going to terminal and typing the following commands:
Backup your xorg.conf file first
If you have an Intel Chipstet 8x - 9x, the 915resolution fix will work for you, however you will have to run this every time you restart Ubuntu. I'm working on a script to automate the installation of 915resolution and fix your startup scripts so that you don't have to run 915... every time you restart. Will try to post it by tonight.
