This isn't making much sense to me at all. I know there are a lot of issues with some DVI cards. I had a friend who couldn't even get to his BIOS settings because the DVI out wasn't enabled until Windows booted and the BIOS was never seen! He had to change brands of video card vender to resolve it. But in your case you're not really switching between DVI and VGA, you're always using DVI out, just converting it to VGA with an adapter and then going in to the VGA in on the same monitor. If Knoppix produces viewable output this way than I don't understand why the monitor couldn't display that same video when it came in on the DVI input. I hope that as you learn more about this that you'll post it.
