So, I'm trying different things to fix my grub installation and I managed to make my knoppix and windows 2k unbootable.

That was a fine time to discover that I had an incomplete burn of the knoppix CD (I must have given away the good burn I made). So the computer was basically hosed.

First I booted from my win2k installation CD and issued a fixmbr from the recovery console, which got my windows back. And I tried to revocer my knoppix from the broken CD. Bad idea.

When I finally got another good burn made and got my knoppix working again I found that I could no loger successfully su to root while logged in as knoppix. I can still log-in as root.

Also, none of the KDE popup windows that prompt for the root password succeed either, and the checkbox to "keep password" is now missing (like when I try to change the time, or some other root level activity).

I figure that this is a permissions issue, since somehow in the above process all the files on my system managed to get owned by knoppix:knoppix instead of root.

I chowned root:root everything but /home/knoppix. That hasn't helped though. Is there a fix permissions script somewhere that I can use to get this thing working correctly?

Thanks in advance,
