Re: [PD] pd patch startup at boot - ubuntu-server

thanks derek!

This all looks very promising! I will try some of this later tonight and i will let the list know what works... (unless someone already knows what works:)

...no im not running X. its optimized to run with just a power cord and and network cord :)

like there should be an easier way to do this.

I took a bunch of notes from various sources on this. Almost all are from posts on the PD list, however I don't have the authors names attached anymore. Apologies to the original posters!

But anyway, you should be able to find a solution somewhere in these suggestions! It largely depends on whether or not you are running X (which I imagine on a server you are not!)

to autostart on linux

put a symlink in your rc3.d (or with whatever runlevel you boot by default, this is set in /etc/inittab)

called S19pd_start (any number, but be sure, all other important processes are started before/lower numbers...) to a script named pd_start

linux then calls this script with the argument "start" when booting. the script "pd_start" looks like:

################################# beginning of script #############################

#! /bin/sh

# Check for missing binaries (stale symlinks should not happen) PD_BIN=/usr/local/pd/bin/pd test -x $PD_BIN || exit 5

case "$1" in start) echo -n "Starting PD" ## Start daemon with startproc(8). If this fails ## the return value is set appropriately by startproc. /usr/local/pd/bin/pd -nogui -noadc -audiobuf 20 -r 22050

   kill 'cat /var/run/pd.pid'
   ;;

 restart)
   ## Stop the service and regardless of whether

it was ## running or not, start it again. $0 stop $0 start ;;

 *)
   echo "Usage: $0 {start|stop|restart}"
   exit 1
   ;;

make an ".xinitrc" file in your home directory. in it put something like:

hdspmixer &

you can also safely put other stuff in there if you like:

jackd -d alsa & pd -jack mypathc.pd & xterm

but you might be better off doing this in some other star script and killing X after you know hdspmixer has been run.
you only need to run hdspmixer once - this initializes the card somehow.

to login to X automagically

use mingetty on tty1 with the option --autologin you set that in /etc/inittab

mine says this: 1:2345:respawn:/sbin/getty 38400 tty1

change it to something like this: 1:2345:respawn:/sbin/mingetty --autologin myusername tty1

where "myusername" is the name you want to log into.

then in .bash_profile under "myusername", you'll want somthing to automatically startx, like this:

if [ -z "$DISPLAY" ] && [ $(tty) == /dev/tty1 ]; then startx fi

###################

Using this script you can run Pd as a daemon:

scripts/debian/init.d/pd

That means you can do this kind of stuff:

/etc/init.d/pd start /etc/init.d/pd stop /etc/init.d/pd restart

You'll most likely need to use it in -nogui mode, but it does that by default. You can configure which user account pd runs
