wake up scripting

[kmchen]

Sorry to come back with that thread but it worked a few days and failed after a while. Reboot or system upgrade ? I don't know.

I recall my simplified script:

Code: Select all

cat /lib/systemd/system-sleep/kmc_reload_sound
#!/bin/bash
#

pid=$(pgrep -xn pulseaudio)\
  && export DBUS_SESSION_BUS_ADDRESS="$(grep -ao -m1 -P '(?<=DBUS_SESSION_BUS_ADDRESS=).*?\0' /proc/"$pid"/environ)"

#sudo -i -u kmc pulseaudio --kill
logger kmc_v2
sudo -i -u kmc cadence-session-start -s
logger kmc_v2_end
#sudo -i -u kmc pulseaudio --start
#sudo -i -u kmc /usr/sbin/alsactl restore

sudo -i -u kmc /usr/bin/play /usr/share/sounds/Kopete_Event.ogg

And I get that in syslog after a wake up from sleep:

DBUS exception again.

Thanks for your help to have a linux sound system 100% working one day !

I just want to launch the simple command

Code: Select all

cadence-session-start -s

that works perfectly when I have X11 workin after resume from sleep.

Any body there ?
