[Lubuntu] Change Brightness

I’m using Lubuntu 14.04 and I found that you will have to make sure “Power Manager” is running for the brightness fn-keys to work.

To start Power Manager, go to Menu > Preferences > Power Manager

Once this is started, you should be able to adjust screen brightness with fn-keys.

Alternatively, you can read off my other post on autostart power manager so you can adjust your screen brightness without going through all the manual-clicking.
