Public bug reported:
the xfce desktop session starts multiple instances of xfce4-power-
manager and xfce4-volumed, rendering power management ineffective and
audio volume buttons dead. additionally, the lid switch causes
hibernation irrespective of power management settings.
workaround:
- edit /etc/xdg/autostart/xfce4-power-manager.desktop and change the
corresponding line to
Exec=xfce4-power-manager --no-daemon &
- edit /etc/systemd/logind.conf and make sure to have this line enabled in the
[Login] section
HandleLidSwitch=ignore
- disable automatic session saving in Settings | Settings Manager | Session and
Startup | General
- logout from your xfce desktop
- login again
- run "ps awxu | grep xfce" and kill (-9) all instances of xfce4-power-manager
and xfce4-volumed
- logout (might take a while for the connection to nonexisting power manager to
timeout)
- login again. run the "ps" command above again and check that there are no
multiple instances of the two processes. if there are, repeat the kill
procedure again, logout and run "ps" again
- at this point starting of multiple instances stops (is there a bug in session
saving?) and you should have properly working power management and volume
buttons
-note that updates of certain packages might reemergence of the symptoms, just
repeat the procedure again
