There is a second related problem I've just noticed with xdm sitting
on the wrong pty every once in a while.

When I run sshd from /etc/rc, xdm which is started a bit later can't
bind to /dev/ttyv0 and instead grabs /dev/ttyv1 with the obvious
results.  X and the getty fight for keboard events and eventually X
loses control of the keyboard.  When I turned off ssh, then X gets
ttyv0 and all is happy.

The workarounds are:

    1) run ssh from inetd
    2) turn off getty on ttyv1

I use both.  Belts and supenders.

(BTW.  Running ssh from inetd with the default key sizes is no big
problem for modern cpu's.  Even a 6 spec-int ppro-150 does that in a
second or two.  Its also more secure and has one less daemon sitting
around twiddling its thumbs most of the time.)
