>Description:
After recompiling the kernel to enable the screen saver in
PCVT, I rebooted the machine with the following /etc/rc.i386 file:
#!/bin/sh -
#
# rc.i386,v 1.9 1995/05/26 18:06:52 rgrimes Exp
# Do i386 specific processing
#
echo -n 'enabling FreeBSD/i386 options:'
echo -n ' pcvt'
if [ -s /usr/share/misc/pcvtfonts/vt220l.808 -a \
-s /usr/share/misc/pcvtfonts/vt220h.808 ] ; then
loadfont -c 6 -f /usr/share/misc/pcvtfonts/vt220l.808
loadfont -c 7 -f /usr/share/misc/pcvtfonts/vt220h.808
for vty in /dev/ttyv* ; do
scon -d $vty -s 50 -t 300 -1
cursor -d $vty -s0 -e16
done
fi
scon -c 1
echo '.'
----
I had enabled both the -t 300 and -1 at the time, since
I wanted to use my console in 132col mode.
After rebooting with those settings, my console would not
switch to either 132col mode, or the 50line mode that I'm using
currently. It reverted to 24/25x80 mode.
When I attempted to edit /etc/rc.i386 to disable -1, to
see if that might be what was preventing the -s 50 from working
properly, the console locked up. Whether it was just the keyboard,
or both keyboard/monitor, I do not know.
After booting into single user mode, and disabling -1,
I once more rebooted the machine, to the same results...25x80,
and the console locking when I tried to disable the only other
"new" thing...-t 300.
for the second time, I had to boot into single user mode
to fix /etc/rc.i386, but am unable to enable either the screen saver
or 132col mode.

enable -t 300 for the screen saver
