Comment 42 for bug 973778

with fresh ubuntu 13.10 and xfce desktop i get this symptomatic behavior (confirmed on several installations):
* at first everything looks ok
* after several logout/logins or after wake-up from hibernate xfce4-power-manager (symptom: no battery status icon) and audio volume buttons stop working, power policies (hybernate, blank screen on lid) do not work, notebook goes into suspend
* "ps awxu | grep xfce" reveals several instances of xfce4-power-manager and xfce4-volumed running, sometimes up to 3 instances of each are observed
* i tried to do "Settings | Session and Startup | Session | Clear saved sessions" since it seems even when "Automatically save session on logout" in "Logout Settings" is set to off, multiple instances of power manager and audiod creep in on login
* killing all xfce4-power-managers and restaring it with --debug seems to get it working while the one without an option produces a non-functioning one (this seems like a bug in the code since it works while a lot of --debug is produced and just hangs when run without an option, i guess it's the same with the --no-daemon)
* logout after killing excessive instances of the power manager and volumed produces a session with single instance of both applications only. unfortunately, notebook's volume buttons stop working (workaround is to assign keyboard shortcuts to audio buttons and alsamixer up/down/mute)
