I suppose R61i has ACPI backlight control. But i compiled the kernel with ACPI video enabled. Will that not take care of this issue? Is there something to do with Root and User permissions?can u give more inputs regarding section starting from line 607( Lenovo models *with* ACPI backlight control) in the above text, like what steps i can do to debug this?
