For Ubuntu you probably want to edit /etc/login.defs and change the UID_MIN
1000 to UID_MIN 500.
It's been a while, so that might be stale advice.
KDE in Debian has a similar issue -- users created with the graphical tools
such as start their UIDs at 500, while users created with adduser start at 1000.
The default kdmrc only lists users with a UID of 1000 or higher
(MinShowUID=1000)
So it's a bad situation where if you use the KDE kuser gui tool to create a
user, that user will not show up on the kdm welcome screen unless you edit
kdmrc first and set MinShowUID to 500. And the funny thing is that it has been
that way for YEARS without being fixed. Sometimes developers just dig their
heels in and refuse to admit there is a problem.
