Hedgehog Linux: Blank Screen Issue with Raspberry Pi Official Touchscreen After Boot

[TanayBole]

Bug Description
When booting Hedgehog Linux on a Raspberry Pi 4 (8 GB RAM) with the official Raspberry Pi 7-inch touchscreen display, the initial boot messages appear on the touchscreen, but after the boot sequence completes, the screen goes blank and remains unresponsive. The issue does not occur when using an external HDMI monitor, which displays the output correctly. Additionally, the Raspberry Pi touchscreen works correctly with other operating systems like Raspberry Pi OS.

To Reproduce
Steps to reproduce the behavior:-

1. Install Hedgehog Linux on an SD card and insert it into the Raspberry Pi 4.
2. Connect the official Raspberry Pi 7-inch touchscreen to the Raspberry Pi.
3. Power on the Raspberry Pi.
4. Observe the initial boot messages on the touchscreen, followed by a blank screen.

Expected behavior
The official Raspberry Pi 7-inch touchscreen should display the full boot sequence and subsequent cli environment as it does with other supported operating systems.
