I only have guesses of where the green dots are coming from, but for now change your /etc/X11/xorg.conf file back to the original settings so you have a monitor to work with and "We" the people on the list know what is going on.

Read bruce_s01 second post

Any changes you make to /etc/X11/xorg.conf will only affect X Windows on the screen or the Knoppmyth front end screen / TV as you have called it. This is the part you have been able to get working so lets not change the xorg.config file.

Now that you are still having problems even after a clean install I think bruce_s01 is looking in the right direction.

Anything before X windows starts is set in /etc/lilo.conf file. Lilo configures your computer on boot. In the lilo file there is a line VGA=???. What dos yours say?

Your VGA modes are set in this statement like VGA=normal or VGA=778

On boot you should have got an error message on your TV like "You passed a undefined mode number (press return) to see modes available" . It might be at this point is where the Knoppix setup scripts may have got something wrong. When you try to go to console (alt-ctrl-f1) or your scrolling boot information on startup you are using the same setting in the VGA=??? statement. This could be where the green dots in console came from.

Post your VGA statement and don't change anything in lilo yet.
