Intel HD Graphic Controllers

With an Intel HD Graphic Controller if passing kernel parameter acpi_backlight does not work, or it freezes and/or crashes, one may try adjusting which backlight interface is used by creating a new file in /usr/share/X11/xorg.conf.d/80-backlight.conf and paste into it the following code:

Section “Device” Identifier “Intel Graphics” Driver “intel” Option “AccelMethod” “sna” Option “Backlight” “intel_backlight” # use your backlight that works here BusID “PCI:0:2:0” EndSection
