Title: Add support for NVIDIA EC backlight Status in HWE Next: New Status in linux package in Ubuntu: Confirmed Status in linux-oem-5.14 package in Ubuntu: Invalid Status in linux source package in Focal: Won't Fix Status in linux-oem-5.14 source package in Focal: Confirmed Bug description: [Impact] Some system equipped with NVIDIA GFX cannot change screen brightness. [Fix] Add new way to change brightness. [Test] After the fix is applied, there's a new backlight sysfs "nvidia_wmi_ec_backlight" can change the screen brightness. [Where problems could occur] The driver relies on BIOS to behave correctly. If the BIOS lies or has a bug, the new backlight interface will overtake other backlight interfaces. It's rather unlikely though.
