On two different linux boxes (kubuntu fawn and Knoppix 5.01), I have lost
my ability to do "su". It is rejecting the password. Now I'm sure I have
not forgotten the root password, as it was very memorable, and I can still
log in with the "regular user" password, and it rejects this main user
password. I'm at a loss to explain or fix.
1) Linux, if you don't use su for a year, locks it up until you use command
_____________.
2) I really did forget my root password. (Yikes, must I re-install??)
3) I caught a virus.
None of these options make sense.
(I'm asking here because one local linux forum accuses one of spreading FUD
if you ask difficult questions).

kubuntu, I do not know, but Fawn on ubuntu I do.
Modern (recent) distribution (or update) more and more require
either to be in the wheel group to be able to su.
Ubuntu is even stranger: for uni-personal installation, there is no
root password per default (none that you can type).
All is done with sudo (not su).
Whenever root level is requested by the Gui, you must provide the
"first user" password (the one which installed).
If you want su back, you need to set a password for root with "sudo
passwd root" first.

No. This was discussed in another thread some weeks ago. If you have
direct access to the computer, you can change the root password.
(The easiest way to do this is, afaik, to get into single user mode.
man init.)
