RPI3 + Offic.7" TouchScreen + IQAudio DigiAmp+ = Grey screen

Help and Support Help
1

Starting from the latest official Volumio release available yesterday (sunday 17-12-2017) and trying to install TouchScreeen plugin immediately after (and even before) the configuration Wizard, I always end up with a grey screen with a mouse pointer in the middle.

  • If I connect a mouse and make a right click, I have a few options for OpenBox.
    ** Starting the browser is refused because it is logged in as root.
  • Ctrl-Alt-F1 brings me to the terminal login screen where I can log-in and apt-get install signals that “chromium-browser” is already installed.

I think this problem is probably easy to reproduce with a Rpi3+TouchScreen only.

Thanks a lot for your help / advices !

After searching in the related threads, I found some people recommending to unplug all USB devices before trying to install the TouchScreen. My tests were made with a keyboard, a mouse and a Wifi dungle plugged (I intend to disable the onboard Wifi). I will try again and let know the results…

Success: Fresh VolumIO download (2017/12/16 version) + Rpi 3 with nothing plugged except Ethernet cable + Simplest possible configuration (English, no I2S board, no Wifi) then install Touch Screen Plugin and then only complete configuration (in my case: French, IQAudio DigiAmp+, Wifi). Should be written somewhere in the doc of Touch Screen Plugin !

You can edit the file with nano-editor - type in sudo nano /opt/volumiokiosk.sh

Inside the file I think you have to edit the first couple lines as follows:

xset +dpms xset s off xset dpms 0 0 0

However I’m no expert on this. So you might want to google for “dpms” to get more detailed information.

Thanks a lot Andi!

Thank you, Andi

The xset-command is what I found on the net, but I didn’t find where I have to use it.
It’s the volumiokiosk.sh !! But it’s not alright. The right commands are :
$ xset s off
$ xset -dpms
$ xset s noblank

You have to quote off the command xset dpms 0 0 120 and it works !!

Thanks for bringing me on the right way !!
Best regards
