Can't control brightness












0















Pressing Fn+F11 or F12 (the brightness keys) on my laptop stopped working as soon as I switched from Windows to Ubuntu. I have gone into the settings in Ubuntu and even the brightness control slider does not work. The volume and keyboard slider work, though.
