I pointed out why this was and told you how to make it register one (acpi_backlight=vendor). Then you go on to mention that booting without that, acpi_video0/brightness doesn't control the backlight... but I thought this bug was about using nouveau to control the backlight, not acpi_video... What happens when you boot with that option (but not acpi_osi=Linux/etc unless you normally boot with that)? Does the /sys/class/backlight/.../brightness registered by nouveau let you control the backlight or not? [Note, the Fn+whatever keys are entirely secondary to backlight control working.] -- You are receiving this mail because: You are watching the assignee of the bug.
