I’m wondering if I somehow lost the ability for the display to go blank at idle. I’m using volumio 3.251 on a pi4 with the waveshare 7.9 widescreen. I have the now playing, touch screen, and peppymeter plugin. I have the timeout set to the default 120 seconds. It refuses to blank. I thought peppy or now playing was to blame but it still won’t blank with them disabled. It will just show the last song I played indefinitely. It has never worked so maybe I’m missing something in my configuration.
If that should make no difference you may also try adding
hdmi_blanking=1
to “/boot/userconfig.txt”. IIRC I have seen posts regarding Waveshare displays where it was stated that this setting was needed for the Touch Display plugin’s screensaver to work.
