Package: pulseaudio Version: 0.9.21-3 Severity: normal Tags: patch Hi,
if PA is started as a X session daemon using the script under
/usr/bin/start-pulseaudio-x11, for example during startup of GNOME or
other desktop environments, it will continue to run even if the X
session has ended. If you log into a VT after logging out of X you will
see something like this:
$ ps -fu 1000
UID PID PPID C STIME TTY TIME CMD
1000 15881 1 0 00:13 ? 00:00:00 /usr/bin/pulseaudio
--start
1000 16463 15730 0 00:14 tty2 00:00:00 -bash
1000 16473 16463 0 00:15 tty2 00:00:00 ps -fu 1000
I think this is wrong because PA was started explicitly for the
X-session and should therefore exit with it.
This behaviour is not only annoying because you have needless processes
flying around, but apparently also causes several bugs:
* #556971[1]: "pulseaudio does not remember volume settings, always set to 0"
* #593746[2]: "pulseaudio doesn't support that $XAUTHORITY may have changed
after logout/login"
* #593952[3]: "hotplugging devices doesn't work completely if PA was started
during earlier X-session"
* maybe more?
The attached patch is a dirty hack to shutdown PA once the X-session has
ended. I know that this is no proper way to get the job done, but I
spent the last hour googling for some way to detect the end of a
X-session and didn't find anything remotely useful. This solution
a) does at least work
b) uses very few ressources (almost none)
I therefore think it's a good starting point, however I very much hope
that someone comes up with something not that ugly.
Best regards
