The message that appears when you logout of a virtual screen is
actually suppose to be a menu of some sort so you can choose another
screen to use (without using the ALT-FUNC key sequence).

The line in /etc/inittab:

	S3::sysinit:/usr/amiga/etc/menud&

is responsible for the current behavior.  Remove its entry in the inittab
or change menud to your liking.

A better screen saver would activate when no virtual screen had
received input after a certain time (say five minutes).

Said program would run from inittab and keep track of idle times for
each text screen (/dev/term/con*).  When the timeout occurs it would
create its screen and use SIOCFRONT to force it to the users view.

The program would do something weird until a key was hit then close
then screen and restart.

Look at /usr/amiga/src/cmd/samp.c and /usr/amiga/src/cmd/fractal/* for
examples on graphic screen I/O under Amiga Unix.
