[mythtv-users] mac mini remote hack for ubuntu frontend

With the default Mythtv distribution for Ubuntu, all I was able to do
with LIRC was change the volume. Trying to remap the remote keys
under Mythtv failed with an "unknown key code" error message.
If anyone else is having trouble using the mac mini remote under
Ubuntu Feisty, using the inputlirc package is MUCH easier than trying
to configure LIRC. Is this solution efficient? nope. Cheesy? like a
brick-o-velveeta!
I'm assuming you've installed and configured the ubuntu-mythv-
frontend package (but it should work if the backend is installed as
well).
1. Install inputlirc package:
% sudo aptitude install inputlirc
2. Edit /etc/default/inputlirc not conflict with lirc (I chose /dev/
inputlirc). See my configuration file below.
3. Install the miniremoted perl script below in /usr/local/bin/.
Make it executable.
% chmod a+x /usr/local/bin/miniremoted
4. Install the miniremoted start script below in /etc/init.d/. Make
it executable.
% sudo chmod a+x /etc/init.d/miniremoted
5. Configure Mythtv front-end under Settings->General->General to use
the telnet interface.
6. configure the daemon to start on boot, start the daemon
% sudo update-rc.d miniremoted defaults
% sudo invoke-rc.d miniremoted start
That should do it.
