I'm trying to change the screen resolution to 1024x768 by using the:

knoppix screen=1024x768 command at start up but it keeps booting up with the default 640x480. I've even tried 800x600 and it ignores this too. I've also tried on various PCs and same thing happens.

Suggestions on how to fix?

BTW, I've searched the forum and read the FAQs and have tried the various incantations.

Thanks,
Dale
