I use this to start some mythtv frontends each time they boot. No
login, they just come up running MythTV.
In /etc/inittab
# TERMINALS
#c1:12345:respawn:/sbin/agetty 38400 tty1 linux
c1:12345:respawn:/bin/su mythtv -c startx
c2:2345:respawn:/sbin/agetty 38400 tty2 linux
c3:2345:respawn:/sbin/agetty 38400 tty3 linux
c4:2345:respawn:/sbin/agetty 38400 tty4 linux
c5:2345:respawn:/sbin/agetty 38400 tty5 linux
c6:2345:respawn:/sbin/agetty 38400 tty6 linux
and then inside the .xinitrc file (because I used startx above) in the
mythtv home directory:
myth12 mythtv # cat .xinitrc
# .xinitrc
#exec /usr/bin/fluxbox &
#exec /usr/bin/evilwm &
exec /usr/bin/mythfrontend
myth12 mythtv #
I'm sure someone smarter than me can figure out using init scripts how
to do really fancy stuff, but as I show here I run mythfrontend this
way as well as having tried fluxbox and evilwm. I'm sure you can
/bin/su root and do whatever you want.
Again, __clearly__ this is not an XFCE problem he's experiencing. It's
someone's idea of how to make a Linux machine 'friendly', probably
gone amuck...
Cheers,
Mark
