In the larger sense of "are you having a problem", yes there is a bug somewhere.
But IMO it's not in the nouveau driver. Perhaps discuss this with the person on the other bug who suggested there was an issue in nouveau... I'm not sure
Oh, it's me who suggests there was an issue in nouveau since I don't know nouveau has a logic to check if ACPI video will support backlight control on this system and then do things accordingly.
#ifdef CONFIG_ACPI if (acpi_video_backlight_support()) { NV_INFO(drm, "ACPI backlight interface available, " "not registering our own\n"); return 0; } #endif
I'm not sure if this is correct, I think nouveau can always create backlight interface for user to use no matter if other module do that or not. Just my personal opinion.
