I accidently discovered the remarkable utility of Knoppix when taking Knoppix and a USB flash disk on keyfob on my current trip. So I am tremendously happy devil, stealing the souls of PCs wherever I find them and then returning them later intact, aside from the occasional swapfile.

But I have a question. Is there a way to lock the screen when I leave my KDE desktop. I read that knoppix has locked all passwords and I noticed that the "lock screen" off the main KDE menu is disabled accordingly.

Any ideas?

Thanks, Beck
