First sorry for my bad english. It’s not my nativ language.
I have two 5.5 inch Waveshare Touchscreens, one on HDMI and one on USB c with an USB to HDMI converter, but can’t get it to work.
On officiel Android Firmware i get only one to work, with wrong colours and Inverted Touchscreen, and
At Ubuntu i get no Output.
The only Firmware that work’s with one Display is the Android 9 Firmware made by mo.
There i can choose RGB 8bit and get the right colour, but only for the HDMI Port.
The second Display doesnt work.
I checked the converter with an Other Display and there it work’s.
I have no expirience in Kernel building. So i ask for Help.
