Well when people talk about Linux freedom, more then likely they are speaking of the freedom to choose what you like to use. For example: You can have whatever browser you feel like, whatever window manager, etc... Also along this catagory, it's also free in the way that most of the software for it, such as your CD-Burning applications are free, FTP programs are free, etc...
The reason why people think it's better then windows will vary with each person. My personal opinion is that it doesn't crash, and I'm able to use alot more applications because they are freely avaliable.
In order to login as root, you will need to logout of your current user, then type root at the CLI (Command Line Interface) aka Console. Then you'll have to enter the root password. If you're using the graphical user interface login, I believe there's a selection for root, and a box for the password as well. You can also switch to root from your current user by issuing the command su into a terminal window (aka console) in X. This root is different however. You're root, but you typically inheriet the user's path. Plus you're only root in that terminal window.
About switching resolution's: Try Ctrl+Alt+NumPad + or Ctrl+Alt+NumPad -
If no resolutions higher then what you are using are avaliable to you, then you'll need to edit the /etc/X11/XF86Config or /etc/X11/XF86Config-4 depending on your distrobution. There will be a section as follows:
#************************************************* *****************
# Screen sections
#************************************************* *****************
In this section you will see something like this:
Subsection "Display"
Depth 16
Modes "640x480" "800x600" "1024x768"
ViewPort 0 0
If you wanted for example a 1280x1024 resolution at 16 bit color depth then you'd want to add "1280x1024" behind the 1024 part.
You must be root to edit this file.
