Hi, I don't really understand what you mean. Currently: - acpi_video_dmi_promote_vendor() is called to set the flags - video.ko flags are checked to find which backlight should be used (in order to respect acpi_video="" parameters if user specified them) - if necessary, acpi_video_unregister() is called So yes, the acpi backlight will be register, and then un-registered, but there is no way to fix that (or with a big blacklist in video.ko, and we don't want that).
