Re: [LAU] Linux automatic startup question - Linux-audio-user

It's working!  I went back and removed the logging from the crossover_3chan
command (since it served its purpose), moved the order of the commands a
little, and now it works.  Thanks for the help!!

  Some progress, but it's not working yet.  I added
the log file as
 suggested, and it said something about TERM variable not being set.  I
 Googled that, and added a command like "export TERM xterm" to the QjactCtl
 startup script. That worked, and now:
 1. the log file shows the normal output I should see when running
 crossover_3chan,
 2. ps -aux shows the ecasound process running, under user name gibbyj,
 3. I see what looks like a minimized Jack symbol on the far bottom right
 of my screen, which I don't think I saw before (I did check the box in
 QjactCtl to run it minimized.  Now I kinda wished I had not checked that
 box),
 4. It is not quite working yet; I don't see the output I should see on
 hdspmixer, when I hit a note in Pianoteq, and
 5. Strangely, I can't get QjackCtl to come out of minimized state anymore.
 Clicking on its icon does nothing.  The last command in the startup_utils
 script (/home...crossover_3chan) is now getting done; maybe it is causing
 Qjackctl to hang.  I see /usr/bin/qjackctl as process #3364 in ps -aux.

 Hi,I'm getting my Pianoteq app to run automatically when I start my
  computer.  So
 far, I'm using the startup script in QjackCtl to run the commands I
 need.  I have
 QjackCtl configured to startup automatically.  It's starting up and
 running the
 commands OK; I see the programs come up when I boot the computer.  But
 one thing
 is not working:  a shell script named crossover_3chan, that invokes the
 ecasound
 application, which I'm using for a 3 channel speaker crossover network.
 This
 crossover_3chan script works fine when I run it manually, but for some
 reason,
 running it within the QjactCtl startup script is not working.  When I
 execute ps
 -aux and look at the processes, it's not there, until I run it
 manually.  Here is
 the QjactCtl startup script I'm using:

 #!/bin/sh
 sleep 2
 /usr/bin/a2jmidid -e &
 sleep 2
 /usr/bin/aloop-daemon &
 sleep 2
 export LADSPA_PATH=/usr/local/lib/ladspa:/usr/lib/ladspa
 sleep 2
 hdspmixer &
 sleep 2
 "/home/gibbyj/Pianoteq/Pianoteq 5/i386/Pianoteq 5" &
 sleep 4
 crossover_3chan &

 you might try:
  . crossover_3chan

 Assuming the script does not block.... and maybe even if it does.

 I am assuming that these scripts of yours are chmod +x already.
