Hi rocky.
Oh, groan, so you feel my itsy bitsy little detail is actually THE root cause? Bugger. Does that mean i should not bother after all with the grub edit?
BTW, sorry to harp on about this, but it still feels important to me... this identical input h/w combo long-predates Maui, & didn't seem to bother Mint. Is there something fundamentally different about Ubuntu 16.04 &/or Plasma5 that means comparison to old Mint KDE is invalid?
