I am a newbie at linux, so I need a an explanation a 1st day user could understand (literally). I need to be able to change the resolution of the monitor. I have tried hitting "Ctrl"+"Alt"+"+", but this does not work for me. I would prefer an easy way to do this inside of KDE.

Become root.

Create a back up of /etc/X11/XF86Config-4 (copy it to another location)

Open /etc/X11/XF86Config-4 in a text editor.

Find the section "Screen", that will have one or more subsections called "Display".

For the colour depth that you are using change the mode line.

Example mode line:

Modes          "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"

This defaults to 1600x1200, but lets Ctrl+Alt+numPad "+" change the resolution to the other ones. It also lets some programs (typically 3d games) change to a resolution of their choice.
