Title: Xrandr gamma and brightness problem on 4.4.0-34 kernel Status in linux package in Ubuntu: Incomplete Bug description: Situation Xubuntu 16.04 after the automatic update of the kernel, from 4.4.0-31 to 4.4.0-34. If I give a xrandr command that does not change the resolution or the output monitor, but only the gamma and brightness xrandr --output eDP1 --mode 1368x768 --rate 60 --gamma 1.25: 1.25: 1.25 --brightness 1:25 In eDP1 already 60 hertz and already 1368x768 Nothing is happening. The change in brightness occurs if you change the resolution: xrandr --output eDP1 --mode 1024x768 The screen is considerably brighter. After the command: xrandr --output eDP1 --mode 1024x768 --rate 60 --gamma 1: 1: 1 --brightness 1 Nothing happens, but the change of brightness occurs to the resolution change. for example xrandr --output eDP1 --mode 1360x768 or xrandr --output eDP1 --mode 1360x768 --rate 60 --gamma 1: 1: 1 --brightness 1 Loading the previous kernel 4.4.0-31 the brightness and gamma change immediately. Is my first report, I hope it is clear. Thank you.
