Lenovo Ideapad Z400 Brightness Problem

Post by peterbill » 2019/04/24 08:29:12

Bought a Lenovo Ideapad Z400 and installed a Centos 7 on it, however, I am now able to adjust screen brightness. The screen is very dark. When I press F11 and F12 to decrease / increase brightness, nothing happens. Please can someone help here?

Thanks!
