OK let's start over.
From the Kmenu select a ROOT shell.

OR

Open any terminal and become root like so:

su
<password>

When you open the terminal you then have a command prompt just like in windows only it is MUCH more functional. You will use it often, If you are given code it is usually implied that you should enter it in a terminal.

This symbol: $
Indicates that you are a user. Your username might be ksskruthic for example.

This symbol #
Indicates that you are root
When you are root you have complete control over your machine. You can cause great damage when working as root. You must be root to edit or save a file (there are exceptions). Be careful.
-------------------------------------------------------------

There is a file on your machine named XF86Config-4. It contains all the details regarding your monitor, video card, resolution, color depth etc. You can edit this file by entering everything typed in bold in a terminal:

#xedit /etc/X11/XF86Config-4

Now you should have a somewhat large file open in a text editor called Xedit.

In your file named XF86Config-4 you should make sure you have more than one resolution available to use.

Look for the section of the file that looks like this:

Section "Screen" 
   Identifier "Screen0" 
   Device     "Card0" 
   Monitor    "Monitor0" 
   DefaultColorDepth 24 
   SubSection "Display" 
      Depth     1 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection 
   SubSection "Display" 
      Depth     4 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection 
   SubSection "Display" 
      Depth     8 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection 
   SubSection "Display" 
      Depth     15 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection 
   SubSection "Display" 
      Depth     16 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection 
   SubSection "Display" 
      Depth     24 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection 
   SubSection "Display" 
      Depth     32 
      Modes "1024x768" "800x600" "640x480" 
   EndSubSection

Make the lines that say Modes look like they do in this example. These are the resolutions that you are going to use. You may enter your own resolutions if you like. Just follow the examples I have given you above. After you edit the file so that it has all of the resolutions that you want you must be sure to save the file. Then do this:

CTRL+ALT+BKSPC

That will kill your Xserver. The Xserver should restart. Log in again. Then try CTRL+ALT+ +/-

If you cannot make this work you could also do the same thing by booting the Knoppix cd. You would need to mount the partition that has your installation on it and edit the file from there. If you search at this site I think you will find information on how to boot the Knoppix cd, mount a partition, make it writeable, edit files and save files. It is rather easy to do.

Just as u said I checkled out my xconfig-4 file. The screen section is just similar to what u have give me..excepting the DefaultColorDepth was 16. Does taht make-up the problem..??
