1. Create an auto-login executable (assuming you want to run as something
other than root):

int main () {
execlp ("login", "login", "-f", "username", 0);
}

2. Install this somewhere (e.g. /usr/local/bin)

3. Update inittab and set the terminal to point to your autologin executable:

c1:12345:respawn:/sbin/agetty -n -l /usr/local/sbin/autologinusername 38400
tty1

(all in one line)

4. Update your .bash_profile, append something like:

if [ -z "$DISPLAY" ] && [ $(tty) == /dev/vc/1 ]; then
startx
fi

5. Update your .xinitrc to something like:

fluxbox &
exec /usr/bin/mythfrontend &>/tmp/mythfrontend

(assuming you are using fluxbox)

In addition, mythbackend needs to run as well.

Somebody else might have an easier method, for instance using auto-login
features in kdm/xdm etc. The method I mentioned (shamelessly collected
through various hints elsewhere) should be fairly distribution and window
system agnostic.

kdm will permit autologins
don't ask me how to alter the config file, but on my system (gentoo) theres
a "kde login manager" program so u can click the button...

Here's a more convoluted way: Don't use a graphical display manager.

1) copy this to autologinmythtv.c
/*----------------------- BEGIN ----------------------*/
int main(){
execlp( "login", "login", "-f", "mythtv",0);
}
/*----------------------- END ----------------------*/

2) then gcc -o autologinmythtv autologinmythtv.c
3) copy the resulting binary (autologinmythtv) to /usr/local/sbin

4) change /etc/inittab to autologin myth in run level 4
########################################################
replace: (in /etc/inittab)
1:2345:respawn:/sbin/getty 38400 tty1
with these two lines:
1:235:respawn:/sbin/getty 38400 tty1
myth:4:respawn:/sbin/getty -n -l /usr/local/sbin/autologinmythtv 38400 tty1
########################################################

5) change your initdefault thusly: (also in /etc/inittab)
########################################################
id:4:initdefault:
########################################################

6) Get rid of display managers in runlevels below 5
(they shouldnt be there anyway)
########################################################
rm /etc/rc[234].S99?dm
########################################################

7) Put this in the mythtv users ~/.profile (you will probably have to create it)
########################################################
/usr/bin/X11/startx
logout
########################################################

Now when the computer boots, It will go to run level 4, autologin mythtv,
start X-Windows and assuming you put mythfrontend in the mythtv users .xinitrc,
It will boot right into myth-frontend.

Then if you want to do maintenance chage the initdefault to 3 for text login
or to 5 for graphical logins.

The way I did it on a Gentoo box was to change the initlevel to 3 (multiuser).
Then add this line:

su - mythuser -c "source /etc/profile && export HOME=~
&& /usr/X11R6/bin/startx"

to the /etc/conf.d/local.start (/etc/rc.d/rc.local on other distros). The
mythuser has a .xinitrc file that look like this:
xset -dpms s off
twm &
mythfrontend&

Reboot and enjoy!!
