Here is what xubuntu.org has to say about this:
[...]
Currently, when locking, it is assumed you are either:
- in a public space of sorts (the desktop at home hardly needs locking) and have walked away from the machine
- using a system with more than one user
Stopping/pausing playback in both of these scenarios make sense.
However, this might be an annoying change for users used to having
their music playback continue even when their session locks. If you
don’t like this behavior, there are basically two solutions:
- Set light-locker to lock the session “When the screensaver is deactivated”
- Switch back to using xscreensaver
- Add your user to the
audio
group on your computer and music playback will continue also with light-locker
The first option is a good workaround, because it means that your
audio-playback will continue when the screen has been blanked.
However, when you wake up your computer, e.g. by touching the mouse,
it will pause the music until you log into your session again. The
third solution is mentioned last, because it is not advised to add a
user to the audio
group (read The Audio Group wiki page for a
comprehensive explanation). However, as long as you are on a
single-user system, this might still be an option for you. [...]
Figure 1: Light-locker, by default, will lock out sound.
For those who choose workaround 2, here is how to remove light-locker
and install good old xscreensaver
:
sudo apt-get purge light-locker light-locker-settings
sudo apt-get install xscreensaver
After installation, a "Screensaver" icon will appear in the "Settings Manager" menu. Clicking it allows to configure xscreensaver
.
