Hi folks, **(SOLUTION: Comment out the original FullPageOS ‘dtoverlay’ which makes the HyperPixel ‘dtoverlay’ line the default one - within config.txt on /boot)** To begin with - my HyperPixel works fine (except for some peculiarities, which I can detail in another post) based on latest stretch and following the [Pimoroni install instructions on Github](https://github.com/pimoroni/hyperpixel) * * * After this, I got another SD card and installed ‘[FullPageOS](https://github.com/guysoft/FullPageOS)’ on a Raspberry Pi 2 ver 1.2. - FullPageOS: A Raspberry Pi distribution to display one webpage in full screen. It includes Chromium out of the box and the scripts necessary to load it at boot. This repository contains the source script to generate the distribution out of an existing Raspbian distro image. I then did update / upgrade the distro - and then cloned the [HyperPixel repository](https://github.com/pimoroni/hyperpixel) and ran setup.sh Everything seemed to run smoothly, with SSH working as VNC service showing that the default app ‘FullPageDashboard’ was working on Chomium remotely… _(You can see more context here - in the issue I raised on [‘FullPage OS Github site’](https://github.com/guysoft/FullPageOS/issues/217))_ Please see output of ‘systemctl --full | cat’ further below. **Hoping someone can identify an issue there…** Cheers, Michael. ``` LOAD ACTIVE

I may be missing something, but I don’t think you’ve described a problem? What’s not working on the HyperPixel with FullPage OS? ---

Yeap, explaining my issue would be handy 😝 Basically no display from HyperPixel, just the backlight on but no display of Chomium as is supposed to happen with FullPageOs. I can ssh in and see Chromium over VNC but HyperPixel shows nothing. ---

Hi @gadgetoid ! Any illumination on this would be most welcome… Any other files you need to assess root issue? Cheers, Michael. ---

Curious, what do you see in your `/boot/config.txt` on the FullPageOS setup? I just had a quick dig through their GitHub repo and it seems like nothing more than a couple of scripts that run on boot to run a webserver and full-screen browser instance. Also what process did you use to update/upgrade the distro? ---

Hi @gadgetoid Before HyperPixel install - only three lines were active / uncommented in config.txt on /boot as follows - dtparam=audio=on start\_x=1 dtoverlay=vc4-kms-v3d Above was taken after initial sudo update and upgrade.

Hey! I noticed there was two ‘dtoverlys’, one original and one that HyperPixel introduced… So I commented out the original ‘dtoverlay=vc4-kms-v3d’ - **leaving the ‘dtoverlay=hyperpixel’ to be the default** - and hey presto, it works! Cheers, Michael
