Try:

sudo /usr/bin/xbacklight -set 75

Does it change?

  it does change brightness, but the problem still persists. It still Hangs if i try to adjust it by hotkey and brightness and lock menu in the All setting menu. Will i have to always change brightness by terminal.

I suggest you reoprt a bug
