I’m on Raspberry Pi 3+, Manjaro-ARM minimal 18.09, fresh install.
When I boot the machine I can use the keyboard just fine. Then when I install some desktop environment (tried with Mate and XFCE, and with
lightdm and LXDM) and reboot, the keyboard and mouse plugged to USB do not work. They’re just generic USB devices.
BUT if I won’t reboot and just run
systemctl start lxdm, the keyboard and mouse work just fine.
How can I debug this?
