i don't know LTSP at all, but it sounds very much to me like you have
two processes actively trying to control /dev/tty2.  One process is a
regular root shell, and the other process is a login getty.

commands that you type get fed to both processes, which deal with them
differently.

the root shell, for example, interprets 'student' as a command, and
says (reasonably) 'command not found', while the login getty
interprets that as a username.

the login getty doesn't echo your password, but the root shell does
(because it thinks you are typing another command).

To fix this, i'd try a couple things: 

0) Get rid of the login getty:

  look in whatever file passes for /etc/inittab (i don't know where
  that would reside in LTSP) and comment out the line that looks like:

2:23:respawn:/sbin/getty 38400 tty2

  by putting a # sign in front of it.

or, instead, you could:

1) move the root shell to an unallocated vt:

  maybe use SCREEN_08 = shell in your lts.conf instead of SCREEN_02 =
  shell?

  Then you'd access the root shell with Ctrl+Alt+F8 instead of
  Ctrl+Alt+F2.

Hope this helps,
