That depends.  Why are you using vendor backlight support instead of ACPI
backlight support?

If it is not being done on purpose, there is something fishy going on, or
you have disabled acpi "video" support.

As always, please check if you don't have to do a firmware (BIOS/EC) update
when any such weirdness happens.
