Hi! I have an Omen by HP 15-ce004la with NVIDIA GTX1060 Q-MAX and the bug is still present.
This is my setup: Ubuntu 18.04 with kernel 4.18.13-041813-generic I'am getting acpi errors like this one below in boot time too: [ 0.104082] ACPI BIOS Error (bug): Failure creating [\_SB.PCI0.XHC.RHUB.GPLD], AE_ALREADY_EXISTS (20180531/dswload2-316) My /sys/class/backlight folder is empty, but xbacklight works. I am using latest Nvidia propietary driver. Regards and hope you can solve this soon.
