Prevent suspend while audio/music playing. - Solved

[jaygambrel]

I have been looking for a reliable way to prevent Linux Mint 19 - Cinnamon from suspending while I am listening to music. I want the machine to suspend after the music finishes playing. Caffeine only works for applications running full screen so it does not do what I need it to do. I have found a few potential links that were helpful:

https://superuser.com/questions/393448/ ... ash-script
https://ubuntuforums.org/showthread.php?t=2232064

I used these to write a very basic script that that will change the suspend timeout in Cinnamon's power settings using gsettings to "Never" temporarily while music is playing and then revert when the music stops. This is my first real attempt at a script so if you can improve on it feel free. It will likely only work in Cinnamon though.

if [ ! -d ~/.config/audiocaffeine ]; then
    echo "Configuration directory not found!"
    echo "Creating ~/.config/audiocaffeine"
    mkdir ~/.config/audiocaffeine

# Restore previous value for AC suspend timeout if script
# was interrupted.
if [ -f ~/.config/audiocaffeine/acsuspend ]; then
    echo "Restoring previous AC suspend timeout."
    read acsuspendtime < ~/.config/audiocaffeine/acsuspend
    gsettings set org.cinnamon.settings-daemon.plugins.power sleep-inactive-ac-timeout $acsuspendtime

    else
        echo "No audio detected."

It seems to work for me so far. If anyone has any suggestions to make it more reliable/efficient please feel free to post modifications. If anyone would like to modify it to work with Mate for those using the Mate edition, feel free.

I have done a little more work on the above script and it should now work in Mate as well as Ubuntu running Gnome. I have tried it out on Live USB versions of Linux Mint 19 Cinnamon and Mate as well as Ubuntu 18.04 - Gnome. I hope this comes in helpful for a few other people.

Or here is a version that uses ALSA instead of Pulseaudio. The Pulseaudio version incorrectly reported sound playing when I opened the Sound Settings in System Settings and wouldn't stop until the System Settings application was closed. I haven't tested it as thoroughly though:

How to install this script in Cinnamon:

1. Begin by opening the text editor as root and creating a blank file for the script. Open a terminal and type or paste the following command into it:

Code: Select all

sudo xed /usr/local/bin/audiocaffeine.sh

2. Enter your password when asked for it.

3. When the text editor opens, copy and paste the script from the Linux Mint forum into the text editor and select File > Save

4. Close the text editor.

5. Go back to or open a new terminal. Use the following command in the terminal to make the script executable:

Code: Select all

sudo chmod +x /usr/local/bin/audiocaffeine.sh

6. Enter your password when asked for it. You can now run this script from the command line by typing audiocaffeine.sh or double clicking it using "Files".

7. To add it to your Startup Items so it runs at login, begin by opening System Settings > Startup Applications

8. Click the "+" button at the bottom of the window and choose "Custom Command".

9. Add whatever "Name" and "Comment" you want in those fields and add a startup delay if you wish. For the "Command" field enter:

Code: Select all

/usr/local/bin/audiocaffeine.sh

Or you can Browse to that location and select the file using the "Browse" button.

10. Click Save.

11. If you want to run the script now Click on the gears button beside the "-" button.

12. To see if the script is running open System Monitor and "audiocaffeine.sh" should be listed as one of the processes.

13. When audio is playing, the Suspend times in your Power Settings should flip to "Never" after audio is detected. It will take up to a minute as the script only checks once a minute. Your settings should revert the next time it detects no audio.

hi
this is the first time i take part in your forum
this script works well. i tried the first for cinnamon and it works as intended.

is it possible to create a script for linux mint 19.1 xfce edition

thanx in advance

[jaygambrel]

Hi nashalm,

I apologize for my late reply. Thank you very much for the feedback. I have not used XFCE before, but I am open to trying to modify the script. It might take me a while to figure out how to change the power settings in XFCE from the terminal as I don't thing the gsettings command will work in XFCE as it is not Gnome based. I will look into this though.

Thanks again for the feedback.

Of course, a big shout and thanks to jaygrambel for developing this script in the first place!

PS. I do recommend using pulseaudio though. Because jay's Alsa using '/proc/...' to detect whether an audio playing or not, problems emerge when let's just say for example, you pair a bluetooth speaker as the output of your sound.

Good point, and welcome to the forum.

Also, another way this can be accomplished on Xfce is with Presentation Mode which can be toggled with this:

Code: Select all

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode -T
