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. -- You are receiving this mail because: You are watching the assignee of the bug.
