Inhibit suspend when Clementine is playing music on KDE

sinisab89 · 28 February 2021 12:36

Hello!
I use Clementine for playing music on Manjaro. It’s the best player but a bit outdated so it doesn’t prevent Manjaro going to sleep when music is playing. I have a script i found on Linux Mint forum that inhibited suspend as long as audio is playing, and it worked great for Mint and Cinnamon but it doesn’t work on KDE.

    #!/bin/sh

# Audiocaffeine - Pulseaudio

# Works in Linux Mint 19 - Cinnamon, Linux Mint 19 - Mate, Ubuntu 18.04 - Gnome

# Script to temporarily set suspend timout for AC and battery to "Never"
# while audio is playing.  It then reverts the settings when audio is no longer detected.

# Determine if a valid desktop environment is running and exit if it doesn't.
echo "Reported desktop environment: ""$XDG_CURRENT_DESKTOP"
if [ "$XDG_CURRENT_DESKTOP" = "X-Cinnamon" ]; then
    actimeoutid="org.cinnamon.settings-daemon.plugins.power sleep-inactive-ac-timeout"
    batttimeoutid="org.cinnamon.settings-daemon.plugins.power sleep-inactive-battery-timeout"
    disablevalue=0
elif [ "$XDG_CURRENT_DESKTOP" = "MATE" ]; then
    actimeoutid="org.mate.power-manager sleep-computer-ac"
    batttimeoutid="org.mate.power-manager sleep-computer-battery"
    disablevalue=0

    batttimeoutid="org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type"
    disablevalue="nothing"
else
    echo "No valid desktop environment is running"
    exit 1

        fi

    fi

    # Pause the script for 60 seconds before doing the loop again.
    sleep 60s

done

I don’t know how to alter this code so it works on KDE? Can anyone help?

Hi @sinisab89,

According to this page on the classic Forum:

one possibility to prevent the suspend is to use caffeine (Caffeine in Launchpad). it should be also available in the aur

And from the Caffeine website:

A status bar application able to temporarily prevent the activation of both the screensaver and the “sleep” powersaving mode.

So it sounds like it might work.

I’m guessing it can also be done with qdbus.

sinisab89 · 28 February 2021 22:52

I found caffeine today and I’ll try it to see how it works.
I don’t know what to do with qdbus, I am a total dummy for this kind of things

Hi @sinisab89,

For some reason this was intriguing to me. So I looked at the script a bit more carefully, noticing that, while it has support for many Desktop Environments, it doesn’t have for KDE.

So, with my limited knowledge I added support for KDE. Unfortunately there’s no way for me to test it. (I have a hearing problem, so there’s literally no way.)

So here is the changed script. I have absolutely no way of knowing if this will work. Test it and see if it does.

If it doesn’t, try Caffeine again, as I suggested.

    # Pause the script for 60 seconds before doing the loop again.

done

Edit:

You might want to add a sudoers entry so that your user can use those commands without a password.

Hope this helps!

Hey @Mirdarthos ! Thanks for help!

Unfortunately, this doesn’t work. Script now reports that DE is KDE but does nothing. I think it needs something like this

 actimeoutid="org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type"
    batttimeoutid="org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type"
    disablevalue="nothing"

instead of this

systemctl stop sleep.target suspend.target

cause later it calls for $actimeoutid etc.

Mirdarthos · 1 March 2021 17:58

Sorry it’s not working. I’ll have a look again tomorrow. (It’s 19:57 here, and I’m nowhere near a PC.)

sinisab89 · 3 March 2021 22:14

I tried to modify a service I use for suspend inhibition when Samba is serving files.

[Unit]
Description=Inhibit suspend if Clementine is playing music
Before=sleep.target

[Service]
Type=oneshot
ExecStart=/usr/bin/sh -c "! pactl list sink-inputs | grep clementine"

[Install]
RequiredBy=sleep.target

This doesnt work as expected. I get this error:
pa_context_connect() failed: connection refused

Service fails to connect with PulseAudio and PC goes to sleep. Why is that so?
