Hi,
I’m trying to create a GUI project using the examlecode form here:
Running a full desktop in a container (balena.io)
But I need to install the HyperPixel4 screen in the process.
I have tried multiple dockerfile commands without any luck.
I have downoladed the HyperPixel files to rpi3+ to the project folder, but it fails, saying it’s unable to locate the install.sh.
Anyone had any luck with the Hyperpixel display?
Hi
Can you share more details - like your dockerfile?
I see that hyperpixel needs its own drivers from GitHub - pimoroni/hyperpixel4: Driver for the Pimoroni HyperPixel 4.0" Touchscreen Display
And this would be specific to the hardware versions of Pi and screen that you have - so please share those as well
Hi,
Thanks for you reply…
I have an Raspberry Pi 3b+ and the screen is a 4inch HyperPixel with touch.
My docker code looks like this:
FROM balenalib/raspberrypi3:buster
# Install desktop environment
RUN install_packages xserver-xorg-core \
xinit lxsession desktop-file-utils \
raspberrypi-ui-mods rpd-icons \
gtk2-engines-clearlookspix \
matchbox-keyboard
#RUN install.sh
# disable lxpolkit popup warning
RUN mv /usr/bin/lxpolkit /usr/bin/lxpolkit.bak
RUN curl -sSL https://get.pimoroni.com/hyperpixel4 | bash
RUN echo "#!/bin/bash" > /etc/X11/xinit/xserverrc \
&& echo "" >> /etc/X11/xinit/xserverrc \
&& echo 'exec /usr/bin/X -s 0 dpms -nolisten tcp "$@"' >> /etc/X11/xinit/xserverrc
# Setting working directory
WORKDIR /usr/src/app
COPY start.sh start.sh
# Adding things to autostart will cause them to be launchd automatically on starup
# COPY autostart /etc/xdg/lxsession/LXDE-pi/autostart
ENV UDEV=1
CMD ["bash", "start.sh"]
I have tried with the docker file above, and also including the files in the project, but I’m unable to run the install.sh.
Can you also share the error you see?
Also - are you using the 64 bit version of balenaOS?
This is the error:

I’m using the 32bit… balenaOS 2.98.33
I just tried to install raspberian:
And it works perfect with the screen with this as the only modification to the config file:
dtoverlay=vc4-kms-dpi-hyperpixel4
So the balenaOS somehow does not support it…
Maybe because the desktop feature only supports the buster release and not bullseye…
Hi @jesper,
Thanks for getting back with some of the details my colleague was asking for. I’ve pinged concerned team to see if there is something on balena-os that might restrict hyperpixel4.0. One question on your last input:
Maybe because the desktop feature only supports the buster release and not bullseye…
You are using buster is that not the target release you are looking to use?
Regards,
Nitish
I also want to add here that we have successfully used a Hyperpixel 4 on balenaOS in this project: GitHub - balena-io-playground/pixel-buddy - see the section on Hyperpixel settings. Just define a dtoverlay via the dashboard for hyperpixel4-square-pi3
I tried the bullseye release, but all the packeges in the example will not compile on that…
Looks great… What image can I use for the basics?
What I need is to be able to show two buttons on the screen, and handle the touch event of those.
Hello Jesper,
Following @alanb128 project you can see that you need to set up some environment variables in your dashboard(following this guide) for hyperpixel4 to work properly. You can check the variables used in his project at here. Considering you are using a slightly different setup, you can probably try to replace some of these values by the ones in hyperpixel4 RPi 3b+ config (e.g. RESIN_HOST_CONFIG_dpi_timings → CONFIG_LINES.hdmi_timings).
I have now come a step closer… I think…
I have passed in the config parameters from GitHub - balena-io-playground/pixel-buddy
and tried the basic example here:
GitHub - balena-io-playground/pixel-buddy
Now I get the following error. It’s seems like the display is not fully enabled…

Hey @Jesper could you please confirm the variables you are using and the dtoverlay?
Thanks!
Hey @mpous
This is the ones i tried now…
and also the custom configuration:
The display are the 800x480 model…
Could you please try the complete project @Jesper ?
@mpous What do you mean by the complete project?
this GitHub - balena-io-playground/pixel-buddy
i understood that you only deployd the gui container, is that correct?
Yes because I do not use the flowdock feature… So i guess it will fail?
Give it a try, just to see if it works (even if you don’t have the Flowdock token)
