# Ubuntu – How to increase brightness in smaller steps

backlightbrightness

Is there a way to adjust lighting step ? I have Lenovo L520, and Fn + Light Up or Down adjusts by 20%, how can I adjust the step to 10% ? it will help me fine tune lighting at my dark room.

• Install xbacklight by opening a terminal with Ctrl+Alt+T shortcut and type this:

sudo apt-get install xbacklight


then after installation, type these commands in terminal:

xbacklight = 10
xbacklight = 20
xbacklight = 5


this may help.
