I have installed ubuntu in my chromebook (toshiba 2) and the brightness and volumen keys are working correctly. I did not have to install anything. I just changed the shortcuts. However, although I can see the brightness changing, I want to see an indicator to know where in the brightness scale I am. Where can I download this indicator from?

There is no indicator-brightness package directly on main repos, you'll have to add the ppa (Personal Package Archive) from its developers.

Adding the PPA

Run the following command in your terminal to add the ppa:

sudo add-apt-repository ppa:indicator-brightness/ppa

You'll be prompted to accept adding the ppa, press Y and (or simply) Enter to accept.

Install indicator-brightness

First, you need to update you package info after adding the ppa, so run this from your terminal:

sudo apt update

Next you can install indicator-brightness by simply running:

sudo apt install indicator-brightness

Then you can launch the indicator from Unity's Dash, add it to your startup applications, etc.

Hope it helps.

    While this does seem to work, it is so ugly and unhandy that I preferred not to have a brightness indicator instead. Jul 18 '17 at 18:33
