Screen Saver issues (GPIO button)

abasel · September 16, 2020, 9:53pm

Is it possible to have the screen wake up if a GPIO button is pressed?

In case you are using the Touch Display plugin: The plugin wakes up the screen when the playing state of Volumio is changed from “stop” or “pause” to “play”. So if the GPIO button controls the play function the screen should wake up accordingly. Besides that the screen wakes up on keyboard, touchscreen and mouse actions. So if you want to have a dedicated GPIO button for just waking up the screen independently from the playing state, you could use a script that is called when the GPIO button is pressed and that emulates a keyboard input (e.g. “Ctrl” or “Esc”).

Pressing my GPIO play/pause button does not wake the screen up. The music stops and starts but the screen remains blank. After googling, I added the below xset lines to /opt/volumiokiosk.sh but this made no difference.

xset +dpms xset s blank xset 0 0 120

The complete files is as follows

#!/bin/bash
while true; do timeout 3 bash -c “</dev/tcp/127.0.0.1/3000” >/dev/null 2>&1 && break; done
sed -i ‘s/“exited_cleanly”:false/“exited_cleanly”:true/’ /data/volumiokiosk/Default/Preferences
sed -i ‘s/“exit_type”:“Crashed”/“exit_type”:“None”/’ /data/volumiokiosk/Default/Preferences
xset +dpms xset s blank xset 0 0 120
openbox-session &
while true; do
/usr/bin/chromium-browser

done

Just for interest I then tried to disable the screensaver/blank screen using

xset -dpms xset s off #xset 0 0 120

But this also did not work. Even with the 120 part commented out, the screen still switches of at 2min and then does not come back on unless I move the mouse.

Please provide some more information about your system:

What Pi model do you use?
What is your Volumio version?
What is the version of the touch display plugin?
What is the brand and exact model name of your screen?
What software do you use to control Volumio’s play/pause function with the GPIO button?

Further more, please SSH into Volumio, remove your modifications from /opt/volumiokiosk.sh and (from the UI) stop the touch display plugin.

Then execute sudo journalctl -f and restart the touch display plugin. Watch the log while the plugin starts and also in the moment you press the GPIO button to start / pause playback. Post the log entries here or PM me with them.

Hi

Just for some background, this was all working with an installation that I did August 2018 so I know that the hardware does work.

What Pi model do you use? Raspberry PI 3
What is your Volumio version? 2.806 (downloaded and installed today)
What is the version of the touch display plugin? Display Touch 1.1.9
What is the brand and exact model name of your screen? ODROID-VU7 Plus (I found out the hard way that this is not compatible but as mentioned while the touch did not work, the screen saver issue was resolved in the past using " xset +dpms xset s blank xset 0 0 120"
What software do you use to control Volumio’s play/pause function with the GPIO button? GPIO button-listener plugin for Volumio2 0.8.1

volumio@volumio:/opt$ journalctl -f

Just to confirm, my volumiokiosk.sh file is as follows:

#!/bin/bash
while true; do timeout 3 bash -c "</dev/tcp/127.0.0.1/3000" >/dev/null 2>&1 && break; done
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' /data/volumiokiosk/Default/Preferences

/opt/volumiokiosk.sh looks good.

Does the screensaver functionality work without using the GPIO button, i.e. if you operate Volumio from another device (PC, smartphone) by using the GUI play / pause button?

Thanks gvolt, you have helped me sort it out! Enabling “No screensaver while playing” fixed it i.e. if the screensaver kicks in, when I press the play GPIO it switches on again and then stays on as long as it plays.

Just for interest, here is the project that it is part of: https://www.instructables.com/id/Jukebox/

Impressive work, looks excellent!

One hint regarding the modifications of /boot/config.txt: The hdmi* related changes could be placed in /boot/userconfig.txt instead. Using userconfig.txt has the advantage that this file remains untouched when Volumio gets updated. In contrast the /boot/config.txt file gets overwritten on each Volumio update (further information) and you would have to edit /boot/config.txt again.

Thanks for that. I have added your note to the project; will update properly once I get a chance to apply it myself. Indeed it is a much better approach
