/etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

sudo update-grub

if this does not work then try

/etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=video"

sudo update-grub

Also create the file /usr/share/X11/xorg.conf.d/80-backlight.conf but content is slightly different from the file that you created:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"     "sna"
    Option      "Backlight"       "acpi_video0"
    BusID       "PCI:0:2:0"
EndSection
