I recently started working on a mythtv box and I an currently
using RH9 and KDE. Your request is fairly broad, but I'll touch on the
elements that I remember and maybe that will help even if non
comprehensive. Note that I am not using irexec at this time. For
starting mythbackend as well as some other stuff, I have the following
in /etc/rc.local:

# Force btaudio to load
modprobe btaudio

# Fire up the myth backend
export QTDIR=/usr/lib/qt-3.1 && /usr/local/bin/mythbackend > /var/log/mythbackend.log 2>&1 &

# Provide normal user access to hardware screen resizing
/usr/sbin/nvtvd > /dev/null 2>&1 &

KDE has an auto-login feature, but I was playing with different
window managers so I decided not to use this. Instead, I run mythtv with
a user named "mythtv", imagine that :) In order to get this user logged
in on boot, I changed the following line in /etc/inittab:

#1:2345:respawn:/sbin/mingetty tty1
1:2345:respawn:/usr/bin/openvt -f -c 1 -w -- /bin/login -f mythtv

This causes the virtual terminal on tty1 to auto-logon to the
mythtv account. Notice that the mythtv user therefore does not even need
to have a valid password. I then placed a short routine in the mythtv
user's .bash_profile:


export PATH=$PATH:/usr/local/mythtv/bin:/usr/lib/qt-3.1/bin
export QTDIR=/usr/lib/qt-3.1

/usr/bin/aumix -L

if [ "z`ps -aef |grep X | grep -v grep`" = "z" ]; then

while [ 1 ]; do
startx
sleep 5
done
fi

Obviously the aumix line restores the mixer settings. The "if"
construct avoid starting X twice if I su to the mythtv user. The while
loop causes X to restart if it should die - this is handy when I forget
for example that PIP isn't working yet because I'm still using a non
full-duplex sound driver and so I can Ctrl-Alt-Backspace to kill X and
it will start back up. The 5 second pause is so I can break out of the
loop if I really want to drop tty1 to a terminal session.

In order to get mythfrontend to startup automatically, I placed
the following code in "~mythtv/.kde/Autostart/myth"

#!/bin/sh
xset -dpms s off
exec /usr/local/bin/mythfrontend

I tried using a soft-link, but for some reason this caused two
instances of mythfrontend to startup. The xset shuts off the DPMS screen
blank, though I also had to disable the KDE screen blank.

So that's how I did it. Now if I could just get alsa working
with the on-board sound on my Asus A7V8X-X, grrrrr...

I used these lines in /etc/inittab:

1:235:respawn:/sbin/mingetty tty1
myth:4:respawn:/usr/bin/openvt -f -c 1 -w -- /bin/login -f mythtv

That way, I can change the default run-level and get a normal
workstation again. You didn't say that you disabled starting X in
run-level 5 (which would be the default) but I assume you did that.
With the above set up, you need to make sure everything you need for
mythtv to work is started in run-level 4.

I used the above more or less verbatim!

I used this as the .xinitrc for the mythtv user:

xset -dpms s off
irxevent &
blackbox &
sleep 2 # probably not necessery
exec mythfrontend

(Note: I'm using blackbox here, but you could substitute any simple
window manager you'd like to try in the above file.)

Thanks Poul, without your post I'd probably still me fiddling with this.
