reinstalled antergos off 17.10 iso today. Install and live medium worked pretty fine. Rebooted - and now I’m unable to use my laptop keyboard anymore. I’m stuck in login screen, the keyboard backlight (HP EliteBook) is on, touchpad and mouse stub work too, but key do not seem to generate input. Switching to a tty also is just possible using an external (USB) keyboard. In a tty however, laptop keyboard works fine. Switching different display managers doesn’t change anything. So far I haven’t really find any other helpful clue. Am I the only one left with this issue? Any hints on how to resolve this?
