adjust brightness on ubuntu

recently I'm trying Ubuntu OS which has been installed on my USB stick.

And I found that my screen brightness is too high.

In order to resolve this issue,

apt-get install xbacklight

after that, I can use my laptop's hot key to adjust the brightness of screen.

This makes me feel good,

but, while I found the touchpad isn't work well on 3, 4 finger gesture,

I was upset, again :(
