Well, I don't have KDE or Gnome installed :) Only Windowmaker and FVWM
but they aren't used. My .xinitrc just has a few "xset" lines in and
the path to the mythfrontend binary itself and nothing else. When I
used FVWM as window manager it windowed the video playback which annoyed
me - removing FVWM as window manager sorted it.
Look, no "windowmaker" or "fvwm" in ps aux:

But if I add in fvwm in my .xinitrc file, I get all the above again, but
also the following line from ps aux:
piers 686 1.1 0.9 4924 2436 vc/1 S 01:55 0:00 /usr/bin/fvwm
But I don't need fvwm, so I remove it from my .xinitrc file. Still
works, and don't have the windowing problem. Acutally it's probably
fixable, but I don't strictly need a window manager.
Actually I think you can say "You're using Mythfrontend as a
display/window manager"
It doesn't matter anyway, the frontend calls "halt" to power off as
default - and I've added in so that sudo allows the user that runs the
frontend to run halt without entering the password. Works fine. Sure,
someone can log in as "piers" and call the halt command via sudo, but
it's a dedicated frontend machine, who cares? ;)

If you are using X, then you are still using a display manager whether
or not you have automatic login. If you want to be able to shutdown
from mythfrontend, then you need to match you display manager with your
desktop manager. i.e. kdm if using kde or gdm if using gnome.
KDE and Gnome tie into their display manager's admin access to shutdown
or restart the server.
So if you're using KDE, use KDM and then you can shutdown your server.
To use KDM edit /etc/sysconfig/desktop and add:
DISPLAYMANAGER="KDE"

No display manager and not using KDE.
When the computer boots up, it loads mythfrontend on its own. No
log in
manager, nothing. It's intended to be used only for a frontend in my
bedroom, so no big deal if someone hacked in and powered the frontend
off - very unlikely anyway.
Hmm. But then again, the files for the frontend is on the server
(diskless frontend using netboot you see) so the halt command is open to
all on the server.... best check that then! Hmm, I seem to be able to
access halt via my server as a non-root user - not going to actually
invoke the command though! Maybe best to move the halt command
somewhere else, rename it to something like "fluffy_teddies" - no-one'll
find it...?
