When I use Manjaro ARM kde 18.12.1 with the official Raspberry Pi Touchscreen and a Raspberry Pi 3 b+ the screen shows the boot sequence and then displays a black screen where Manjaro would normally show the login screen.
I know that the touchscreen works and is plugged in correctly because when I boot into the latest version of Raspbian the touchscreen works perfectly.
I’ve also tried updating the firmware using
sudo pacman -Syu which seems to make no difference in the touchscreen issue.
Normal hdmi output seems to work properly, and I suspect that the hdmi output is still being used by the Pi even when no monitor is plugged in to it.
Any help would be appreciated!
I am also relatively new to Arch Linux so please forgive me for overlooking anything obvious.
