Could you please post the result of
xset -display :0 q when the screensaver timeout has been set to 0 and also when the timeout has been set to 10 seconds?
What you could do, too, is watching the log with
sudo journalctl -f at the moment where you save the screensaver setting from the plugin’s configuration page and also when the screensaver should shut off the screen. Please post the result here or (maybe better to not clutter this thread) PM it to me.
Edit: If possible test the screensaver function using another HDMI monitor to rule out an issue with your touchscreen.
You can try the
--force-device-scale-factor flag. It requires editing /opt/volumiokiosk.sh. You can open this file with
sudo nano /opt/volumiokiosk.sh. Then search for the section starting with
while true; do and add e.g.
--force-device-scale-factor=1.5 \ so it looks like this:
while true; do
--simulate-outdated-no-au='Tue, 31 Dec 2099 23:59:59 GMT' \
To save the changes hot “Ctrl+x”, “y” and “Enter”. After that disable and enable the touch display plugin.
Another method to scale chromium is to connect a keyboard to your RPi and use “Ctrl”+"-" respectively “Ctrl”+"+". Note that you need to use the “-” or “+” keys from the number block.
P.S. What is your Raspberry Pi model?
