I tried this on my F13 this afternoon and I've just spent an hour or
more digging back out of the hole it left me in...

After making that change and rebooting (reboot is probably overkill)
it came back to the login screen with a gdm window ONE PIXEL WIDE.
I couldn't figure out how to place the mouse so I could log in.

NM is configured to bring up wireless when someone logs in, so that
wouldn't work. but by sheer chance I had previously configured the
wired network to come up on boot, so I could log in via ssh to 
poke around.

I finally "fixed" it by renaming the directory /etc/gconf/gconf.xml.mandatory
to something else then creating an empty dir of the same name.

before renaming it, I could run gconf-editor (via remote login) but it
claimed that 'disable_user_list' was read-only and wouldn't let me
change it. :(

So, it looks like either I was incredibly unlucky and accidentally
tweaked something else I shouldn't have, or else this doesn't work on
F13.

I'd love to get rid of the user list. (one wonders: just because Windoze
exposes all the users to anyone walking by, does that mean Linux therefore
must do the same stupid thing?)

Anyone else know how to turn off the user list on F13?

Thanks!
