Debian (Ubuntu) question - CTL-ALT-Fn to switch consoles

[Collins Richey]

Although I use the CTL-ALT-Fn function to switch to another console at
work regularly (RHEL & RH9 systems), I hadn't needed to do this at
home for a long time, and to my surprise it does not work well on
Kubuntu 6.06 (no idea whether it ever worked).

When I switch to a new console, I get the login prompt, but login is
not possible because the console appears to be ignoring linefeeds.
When I key my userid, the password prompt appears on the same line,
and as soon as I start to key a password, the cursor drops to the next
line and echo suppression disappears (I can see what I'm keying).
Needless to say, the login does not work.

Does this ring a bell with anyone? Is this a known problem on Debian systems?
