So I bought a Hyperpixel 4.0 touch display a while ago, but I have not succeeded yet in getting it up and running with Rpi Zero W.

My problem is:

  • My Rpi Zero W works perfectly fine before the one-line installation.
  • After the installation is complete, the system reboots but both the HDMI and Hyperpixel screen stay blank.
  • In SSH, I shut down the Rpi. After removing the installation manually, the Rpi works fine again.
  • In SSH, I tried to run hyperpixel4-init, but it didn’t do anything apparantly.
  • The hyperpixel screen stays blank with the backlight LEDs glowing, so I assume the hardware is fine.

Can anybody please help me? I do not know what else I can do to try to fix this.
