Please run "ls /sys/class/backlight/" to see what backlight interfaces
are available.
You may also want to try the kernel parameter for backlight such as
below
acpi_backlight= [HW,ACPI]
{ vendor | video | native | none }
If set to vendor, prefer vendor-specific driver
(e.g. thinkpad_acpi, sony_acpi, etc.) instead
of the ACPI video.ko driver.
If set to video, use the ACPI video.ko driver.
If set to native, use the device's native backlight
mode.
If set to none, disable the ACPI backlight interface.
