Hi guys, i might need some help getting LineageOS 20 running on the official 7" Touchscreen.
As mentioned in the "docs" there is an option in Settings: --> System --> RPI Settings --> Touchscreen, which is supposed to config the OS to properly run with the official 7" >Touchscreen.
When applying this setting and rebooting the PI i end up with
1. A Blackscreen on the Touchscreen (backlight on obviously)
2. A Blackscreen on the HDMI0 output (previously worked fine, probably its not supposed to work cause the touchscreen config is active, i don't need it anyways once i get the touchscreen running)
After taking a look at the boot/config.txt and resolution.txt i noticed the dtoverlay=vc4-kms-dsi-7inch
line is uncommented and the resolution is set to 800x480, which seems right to me.
After a little bit more fiddling around i found out that if it boots into TWRP it displays fine on the Touchscreen, although the touch input does not work (which could also be a general thing wor TWRP, idk)
Am i missing something here? I don't seem to be getting, why its not properly booting into android/displaying the actual image.
if i should include some more info or whatever else, feel free to ask me
Thanks in advance for the help.
