Hyperpixel 4.0 Touch AND HDMI0 is blank on Raspberry Pi 4 with Kali Linux and the hyperpixel4 drivers. Why? How to make this usable? Kali ARM 64-bit Raspberry Pi 4 version used is from here: [https://images.offensive-security.com/arm-images/kali-linux-2020.1a-rpi3-nexmon-64.img.xz](https://images.offensive-security.com/arm-images/kali-linux-2020.1a-rpi3-nexmon-64.img.xz) hyperpixel4 drivers and instructions used are here: > **[pimoroni/hyperpixel4](https://github.com/pimoroni/hyperpixel4/tree/pi4)** > > Driver for the Pimoroni HyperPixel 4.0" Touchscreen Display - pimoroni/hyperpixel4 Removing HDMI0 and rebooting after install produces a backlit Hyperpixel 4.0 with no text or any image at all. Inserting the HDMI0 with the Hyperpixel 4.0 installed produces a four color pattern with no text on the Pi 4 and a backlit but blank Hyperpixel 4.0 So, how do I debug this? How do I get this to function with the Hyperpixel 4.0 display? ---

The Pimoroni Hyperpixel driver is written for Buster, the 32 bit version of Buster. How did you install it on Kali? ---

Kali actually has the options built in now in the raspi-config LCD screen settings. I am having an issue trying to get it to install on a RPi 400 with the CyberHAT and the HyperPixel 4.0 screen. In 64-Bit mode, if I use the raspi-config method, I get black screens on both HP4.0 as well as HDMI, and if I use the CURL method it won’t install, stating hardware is unsupported. If I try in the 32-bit version, raspi-config method also gives me the black screens, and CURL method gets me through the full install, but on reboot it hangs at the rainbow screen. ---

I also have the same problem … Did you manage to get it to work? ---

There is a compatibility issue with the Hyperpixel and cyberdeck. Just a FYI post. [Adafruit customer service forums • View topic - Pi400, Cyberdeck, and Hyperpixel4 (non-touch) not working.](https://forums.adafruit.com/viewtopic.php?f=50&t=179733&hilit=cyberdeck)
