I suspect this may relate to full disk encryption, as everything else was standard. After first install (August 12), I noticed that boot would appear on the desktop, but thought nothing of it. After upgrading the kernel (days later), everything went wrong, no wifi, sound, etc. Found this post: https://forum.manjaro.org/t/wifi-no-longer-works/117162 After updating fstab and copying across the boot directory files to the boot partition, everything was back as it should be. EXCEPT the FDE password is now querty instead of colemak (not sure how to fix that). Anyway, I thought I better report it. Thanks.
