the terminals are generally spawned via the /etc/inittab file:
Code:
# TERMINALS
c1:12345:respawn:/sbin/agetty 38400 tty1 linux
c2:12345:respawn:/sbin/agetty 38400 tty2 linux
c3:12345:respawn:/sbin/agetty 38400 tty3 linux
c4:12345:respawn:/sbin/agetty 38400 tty4 linux
c5:12345:respawn:/sbin/agetty 38400 tty5 linux
c6:12345:respawn:/sbin/agetty 38400 tty6 linux
for example. as you can probably guess each line matches up to a different Fx key... if there ain't no 6th entry, there won't be a terminal there. Having said that i *assume* that if there were no 6th entry then X would load on that screen, not the normal F7...
