How to get FYSETC HDMI5 HDMI Touch Screen 5INCH DSI Screen MIPI LCD V1.1 work on Raspberry PI

Vendor suggests to use vc4-kms-dsi-5inch overlay, but this provides a text-only mode as DRI isn't working.

# Disable legacy
#dtoverlay=vc4-kms-v3d
#max_framebuffers=2

dtoverlay=vc4-kms-dsi-5inch

Solution

Use vc4-fkms-v3d instead:

dtoverlay=vc4-fkms-v3d

Misc

Screen Rotation

To rotate a screen in text-only mode /boot/firmware/cmdline.txt add param:

fbcon=rotate:2

• rotate:0 = normal
• rotate:1 = 90 degrees
• rotate:2 = 180 degrees
• rotate:3 = 270 degrees

Backlight

Write a value from 0 till 255 to /sys/class/backlight/rpi_backlight/brightness

# Turn off
sudo echo 0 >> /sys/class/backlight/rpi_backlight/brightness
