xbacklight works for me at Ubuntu 18.10.
I have notebook with hybrid graphics but i disabled Intel Graphic in UEFI
settings. I'm using nvidia-driver-390.
I can't test with Intel Graphics cause Desktop does not launch after Login with
Intel GPU.

I confirm that 'xbacklight -set 60' works (as user, no root required),
in both desktop sessions: ubuntu and plasma. However, the Fn key + arrow
only works on plasma.
Being on ubuntu session, inside the directory '/sys/class/backlight'
there is nothing, yet xbacklight works. So it's almost sure a

Note to developers: The tricky thing about this bug is that you may need
a pure Nvidia system. Not a hybrid.

If your backlight is wired through Nvidia then I think you may need to
use the xbacklight interface. You can do it manually by installing:
sudo apt install xbacklight
and running xbacklight ...
If that works for you then I think the problem is that mutter/gnome-
shell isn't

brightness control
I tried also: sudo su -c 'echo 10 >
/sys/class/backlight/acpi_video0/brightness'.
Pressing the Fn keys brings up the OSD brightness control, which
reflects the value of the /sys/class/backlight/acpi_video0/brightness
file (and viceversa), but the actual screen brightness does not change.

@brinstar, yes I did the sudo update-grub part, and tried
acpi_brightness=[native|vendor] which for me makes the Fn hot keys not
working (when you press them, no brightness icon appears).
Last update brought in NVidia drivers 384.90, but no joy, the problem is
still present.

Same problem here.
Ubuntu 17.10 beta 2
NVIDIA Corporation GM204M [GeForce GTX 970M]
Driver NVIDIA binary 375.82
Changing the brightness via Fn keys or via Settings/Power does not work.
Adding acpi_osi=Linux does nothing for me, the problem remains.

You received this bug notification because
I've managed to use a workaround to make the hotkeys work.
I added acpi_osi=Linux to the grub config file and did an update-grub
and it works. But I think it would be better if this was looked into as
it did work fine without the acpi addition on Ubuntu LTS.
