Hi there,
I have the an issue with my USB-touchscreen and my RPi 4. Everything works fine, except for when i try to connect to the carlinkit via autobox -> black screen.
In order to make my USB-Touchscreen work properly, i've needed to switch from fkms display driver to legacy. With an hdmi monitor and fkms driver everything works perfectly fine for me. My guess is: Autobox needs the fkms driver - not the legacy?
My setup:
RPi 4 4gb
Raspiaudio Mic Ultra+
CarPiHAT
UGreen Bluetooth 4.0 dongle
Carlinkit CPC200-AutoKit
Mimo Vue HD USB capacitive touchscreen (UM-1080C-G)
The touchscreen is addressed via framebuffer fb1.
(Sorry i'm new to the raspberry pi, this is my first pi project)
