What does the display look like in this state: Solid black, dark gray patterned or …?
What’s the output of
systemctl status -l volumio-kiosk.service
and
cat /home/volumio/.local/share/xorg/Xorg.0.log
when “User Interface via HDMI” is enabled?
Is solid black, no lights and my monitor shut down automaticaly after a few seconds (because no signal)

Since the problem seems to be in how the Tinkerboard installation of Volumio handles the kiosk mode, and since the problem is not related to the Touch Display plugin, I would suggest changing the title of the thread to attract the attention of the maintainers of the Tinkerboard image. E.g.: “Tinkerboard: Kiosk mode won’t start [formerly: Error when trying to install Touch Display plugin]”. If you can’t change the title maybe it’s worth to start a new thread with a title mentioning the Tinkerboard explicitly.
Ok… but still thank you for trying!
I’ll probably try to find a Raspberry PI. Is there a model you would advise for Volumio? And maybe also a sound card for a better audio ouput? I also plan to connect it on this screen Écran tactile FHD 7 pouces, 1920x1200, affichage du paysage par défaut, windows 10 11, Raspberry Pi, Linux, Android TV Box, boîtier de jeu, LCD | AliExpress
Thank you
I’m using a Pi4 2GB for testing purposes. IMHO it has enough power to run Volumio.
About the screen: The display seems to be connected by HDMI and touch via USB, so I would expect it to work with Volumio. Can’t judge the quality of course.
I don’t really have an overview of the available sound cards and their quality, so I can’t make a recommendation.
Can confirm this failure on Tinker Board. Recommend, if the plugin creator is unwilling to support non-pi devices, that the plugin be removed from the listing for that device and this somehow be communicated before download. I just wasted 4 hours on a hopeless effort, thank goodness I didn’t buy the hardware specifically for this purpose.
At least I know what to do with my unused and unwanted RPi’s as it’s mandatory to use the plugin 
[edit] … the creator isn’t unwilling it’s a great guy supporting for many years.
so be nice if he could he would help that is who he is not the unwilling guy you say.

the plugin is not necessary for Thinkerboard, it is already included in the standard image
As soon as time allows, I will create a new version of the plugin that refuses to install on (ARM) devices that already have kiosk mode. As @Darmur already wrote Tinkerboard comes already with kiosk mode.
AFAIK it is currently not possible to exclude plugins for certain device types but just for architectures like ARM, x86 etc.
I also think that the only possibility to give a hint to users before download would be in the description of a plugin. I fear, however, that hardly anyone reads it…

“Unwilling” does not infer malice, it is a simple state of being, I meant no ill by it. Ex: “I am unwilling to go out into the rain without an umbrella”. I apologize if this was misunderstood, I’ll be more careful with word choice, or perhaps more verbose.
@Darmur I will need to review this, I don’t get anything on the display past the grey background and a mouse cursor (Do I perhaps need to shut off the HDMI out?)
Thank you all for the replies.
if he could he would help you in any way that’s why he’s including a check for it in the new releases.
he’s willing to do that. 
better to try with a clean image, maybe the attempt of installing the plugin made the “onboard” kiosk mode not working anymore.
OK. 2 power cycles brought me the kiosk mode. First power cycle just gave grey/cursor, second power cycle brought up the kiosk.
[edit] I am using the MIPI DSI / touchscreen, not an HDMI/USB adapter. Might be related.
Thank you again!
wasn’t aware that this also happend with the Tinkerboard. I know this behavior from the x86 image (white screen instead of grey ). But a reboot also solves this.
Glad to hear things are going!
On x86 the grey or white screen seems to be a standard first boot failure on slower Intel Atom devices. Never had that issue on more powerfull notebooks or Nucs.
I had some success with increasing the timeout in the volumiokiosk startup script, it will be added to a new release soon.

Just for future reference, in case anyone else stumbles across this thread like I did:
I ran into the same issue enabling the touch plugin on a clean install. I initially dealt with an install issue which I ended up fixing with a simple sudo dpkg --configure -a via SSH and reinstalling the plugin.
Second (and which may be relevant for others in this thread) is that X failed to start, which I confirmed by running systemctl status -l volumio-kiosk.service. This reported the following:
● volumio-kiosk.service - Volumio Kiosk

What appeared to be causing this was Xorg.wrap: Only console users are allowed to run the X server. I fixed this by adding the following to /etc/X11/Xwrapper.config (file was empty): allowed_users = anybody.
After restarting the kiosk service with a simple sudo systemctl restart volumio-kiosk.service X worked!
All I had to do after that was add lcd_rotate = 2 to /boot/userconfig.txt because for some reason the rotation option in the settings did nothing and my 7" Pi official touchscreen was upside down.
After all this everything is up and running on my Pi4B+Pi touch+HifiBerry DAC+.
This is a fairly old thread and the problem has (had) nothing to do with the issue your post addresses, as the problem involved Tinkerboard devices (not Pi).
