Alex Deucher <alexdeucher at gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |alexdeucher at gmail.com --- Comment #4 from Alex Deucher <alexdeucher at gmail.com> --- The radeon driver should add a backlight control if the platform utilizes the GPU's backlight controller. If there is no radeon backlight interface, the platform uses some OEM specific backlight control (probably Intel or ACPI). I suspect you will have to use the intel backlight control to control the backlight. -- You are receiving this mail because: You are watching the assignee of the bug.
