Thanks for your answer,

in fact i'm allways on customizing kxstudio but now jack does'nt autostart anymore when i lauch my live cd.

I have checked the /etc/X11Xsession.d/99cadence-session-start file where i found:

Code: Select all

# Cadence Session Startup
# Part 2 - Start JACK (or not), according to user settings

INSTALL_PREFIX="/usr"

CADENCE_SESSION="$INSTALL_PREFIX/bin/cadence-session-start --system-start"
exec $CADENCE_SESSION &

unset INSTALL_PREFIX

I put in /usr/share/kxstudio/config-theme/
ardour2 asoundrc composite config fonts.conf gtkrc-2.0-kxstudio hydrogen jackdrc kde kderc local mozilla non-daw non-mixer phasex qt traverso
with jackrc =

Code: Select all

/usr/bin/jackd -R -P 85 -dalsa -dhw:0 -r44100 -p1024 -n2

    sys.exit(startSession(True))
  File "/usr/share/cadence/src/cadence_session_start.py", line 46, in startSession
    if systemStarted and not GlobalSettings.value("JACK/AutoStart", wantJackStart, type=bool):

I've noticed that, after a recent apt-get upgrade, JACK autostarting at login didn't work anymore in KXStudio 12.04. It was needed to run Cadence manually to start Jack.

Thanks to this thread, I've found the problem: in /etc/X11/Xsession.d/99cadence-session-start, the script "cadence-session-start.py" is invoked with the option "--system-start", but recent versions of this script don't work with that switch; you must use "-s"

So I changed this line in etc/X11/Xsession.d/99cadence-session-start:

Code: Select all

CADENCE_SESSION="$INSTALL_PREFIX/bin/cadence-session-start --system-start"

To:

Code: Select all

CADENCE_SESSION="$INSTALL_PREFIX/bin/cadence-session-start -s"

...And the Autostart Jack at login feature worked again!

It would be good if cadence-session-start.py support both switches.

Bye
