"Ctrl-Alt-Del to login" important for security?

[John McCabe-Dansted]

It seems to me that under the current login system, it would be easy
for a malicious user to run a "fake login screen" and steal the
password of the next user who tries to login.

If so this could be solved by having some key combination guarantied
to open the true login window. E.g. perhaps we could encourage users
to always do a "Cntl-Alt-Backspace" before logging in (i.e. kill
current X session) or  maybe "Cntl-Alt-F7" if we reserve display:0 for
kdm/gdm.
