It seems one should be able to get getty(8) to do this using
/etc/ttys. I tried:
console "/usr/bin/su -l USER -c /usr/X11R6/bin/startx" xterm on
secure
which automatically launched X, but I didn't have access to the
console (i.e., no write permission on /dev/console, no keyboard,
etc.). I looked into fbtab(5), but I'm not sure how this works in this
situation.
Thanks to David Coppa, he set me on the right track by sharing Marc
Balmer's "Starting X11 Applications on OpenBSD at Boot Time." I will
summarize:
Use rc.local to launch X server manually on a virtual terminal and make
sure getty(8) is not listening on that VT. This setup will not require
user login or authentication. It can operate as a kiosk.
First, setup an unprivileged user (USER) that will automatically run X11
and any specified GUI apps. Then add an .xinitrc startup script for the
USER's X11 session. Here we will launch Chrome and load a local web
application.
/home/USER/.xinitrc:
/usr/local/bin/chrome http://localhost/app
Now, just execute X11 as the unprivileged user from the system local
script. Note we are running the X server on display 0 on virtual
terminal 5. The startx script will run the .xinitrc above.
/etc/rc.local:
(
while sleep 1
do su -l USER -c '/usr/X11R6/bin/startx -- /usr/X11R6/bin/Xorg
vt05 :0'
done
) &
Now if Chrome crashes or quits, X will restart and relaunch Chrome.
Finally, make sure getty does not interfere with this finely tuned
operation.
/etc/ttys:
ttyC4 "/usr/libexec/getty std.9600" vt220 off
