So I've got Debian with GNOME on my Clevo N85_87HP6 laptop with a GTX1060 video display adapter plus Intel's integrated GPU. Pressing
fn + f8/f9doesn't change my screen's brightness. I've tried using
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi = acpi_backlight=intel"
and a few other lines like that in my grub file, including a tip to add
i915.enable_dpcd_backlight, but none helped.
# tee /sys/class/backlight/intel_backlight/brightness <<< 100
xbacklight -dec 10
work but I'm unable to make my keys work. I've been digging around the internet since yesterday but I didn't found any solution to my problem.
I've also noticed with
xev that when I press
fn + f8/f9 nothing is detected, but when I press
fn + f5/f6 that are keys responsible for sound volume it detects them normally.
I've also tried making a
20-intel.conf file in
Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0" EndSection
which did not work.
How to make those keys work; is it a problem with acpi?
