I can't change my screen brightness in (K) ubuntu 16.10 I have a Samsung AtivBook 6. My Fn keys is working, but only appears the brightness bar on the screen, but don't change the brightness.

My notebook specs: Intel i5 3230M; Graphics: Intel HD 4000 (Onboard); AMD Radeon HD 8850M (Offboard);

Anyone have a solution?

Thanks

Sorry, I didn't know that you didn't have the slider not working, but still it was easy to find the answer. – Ubuntu User Jan 13 '17 at 12:54

Please add the output lspci -nnk | grep "VGA" -A2 and ls /sys/class/backlight/ to your question. – Hölderlin Jan 14 '17 at 03:42
