For Raspberry Pi OS Bookworm and Bullseye branch
Please download the latest version of the image from the Raspberry Pi official website.
1. Download the compressed file to the PC, and extract the img file.
2. Connect the TF card to the PC and use SDFormatter to format the TF card.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image.
4. After the programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt and save it.
dtoverlay=vc4-kms-v3d dtoverlay=vc4-kms-DPI-5inch dtoverlay=waveshare-5dpi
5. Download the 5inch DPI LCD-KMS display file and put the two dtbo files in the /boot/overlays directory of the TF card, and eject the TF card safely.
6. Turn on the LCD backlight switch.
7. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for more than ten seconds to display normally.
For Raspberry Pi OS Buster branch and Ubuntu system
1. Open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, save, and safely eject the TF card.

Raspberry Pi OS Introduction
On December 2, 2021, the Raspberry Pi OS for Raspberry Pi split into two branches, the Buster branch and the Bullseye branch.
The Buster branch is a continuation of the old system, which is more stable and uses raspicam as the default camera subsystem.
The Bullseye branch adds some new features, including KMS as the default display driver and libcamera as the default camera subsystem.

Add in 99-uinput.rules file.
KERNEL=="uinput", MODE="0660", GROUP="input"
save it and run it in the terminal.
sudo udevadm control --reload-rules sudo udevadm trigger
Then reboot:
sudo reboot
Run after reboot (no sudo needed at this point)
