I have been trying to get my hyperpixel4 weirdly square screen working for about a week now,
I have tried multiple sd-cards, powersupplies and even another screen.
I install a fresh raspberrypi os (32 bit)
Run trough the setup, update the pi and reboot.
After that i have tried running the one line installer but also the getting the specific branch and installing from there.
Sadly whatever i do when i reboot the pi it starts with a blanc command line (only a flickering "_"in the top right) followed by a Welcome to the raspberry pi os desktop screen.
After that its turns black.
I did however find that the touchscreen seems to work as i can see the mouse moving when i open the pi-os using vnc
doing Systemctl enable hyperpixel4-init
gives me the following message: Failed to enable unit: Unit file hyperpixel4-init.service does not exist.
I am trying to do this on a raspberry pi zero W
Hope you guys can help me.
Any advice is welcome!

Try Buster instead of Bullseye. You can get it here under Raspberry Pi OS (Legacy) if you don’t have it.
