I'm stuck with my brightness control options. I have two keys with brightness control (fn + up or down arrow) and they don't work at all. I am on a MSI gl72 6qf, with a nvidia 960M.
I edited the /etc/default/grub which now looks like this :
(i tried acpi_osi=linux; acpi_backlight=vendor ; video.use_native_backlight=1 and it did nothing)
And I still can't change my brightess via my hotkeys. I tried xbacklight who answers me : "No outputs have backlight property".
brightness-controller and brightness-indicator don't work either.
My screen is "undetected" according to system settings.
When I tried acpi_listen, my hotkeys are well recognized so it doesn't come from here.
I'm on the nvidia driver 370.28
EDIT : /etc/modprobe.d/blacklist.conf
