Hi everyone, I have a Sony Vaio CW2 laptop, with an Nvidia GeForce 310M card. I have an issue with screen brightness, which I have reported here -- https://bugs.freedesktop.org/show_bug.cgi?id=31920 As I have asked in my last comment, is there a way to prevent nouveau from exporting the backlight brightness control interface? That way, I could probably use the equivalent interface provided by nvidiabl (https://github.com/guillaumezin/nvidiabl) and have better brightness control. If such a feature does not exist, could it be considered for addition as a kernel parameter? Thanks, Rohan PS: I am not subscribed to the list, please cc the replies to me. -- Rohan Dhruva Rensselaer Polytechnic Institute MS-IT, Class of 2011
