Title:
  No brightness controls and /sys/class/backlight empty after upgrade to
  Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter
  acpi_osi= is a workaround)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This is a case of "Backlight control does not work, and there are no
  entries in /sys/class/backlight" for what lspci reports as "NVIDIA
  Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1)" where the
  kernel parameter acpi_osi= is a workaround.  (The workaround is also
  recorded on Ask Ubuntu at https://askubuntu.com/questions/1030526
  /brightness-on-laptop-msi-gt72vr-in-ubuntu-18-04-with-nvidia-gtx-1060
  -mobile-does/1043598#1043598.)

  The problem is new for me after upgrade to Bionic, although the cause
  might be the corresponding update to the NVIDIA drivers.

  I will add attachments following the instructions at
  https://wiki.ubuntu.com/Kernel/Debugging/Backlight, though most of
  them seem to be uninteresting.  If I can provide further information,
  please let me know.
