There is simple driver: https://lore.kernel.org/patchwork/patch/753233/ https://lore.kernel.org/patchwork/patch/753233/ As noted in discussion, Luminance VCD while worked for my monitors, backlight level 0x6B or legacy 0x13 would be better choice. It then can be used by instantiating it at proper I²C monitor bus, e.g.: insmod ddcci_bl.ko modprobe i2c-dev echo ddcci_bl 0x37 > /sys/bus/i2c/devices/i2c-2/new_device (oh, and it now over 2 years and I still haven't got time to integrate it with DRM display hotplug so it could be upstreamed :(
