Installing Desktop Dimmer on Ubuntu 16.04

Installation of Desktop Dimmer is easy with the use of Ubuntu dpkg package manager. But first head to Desktop Dimmer releases page and make sure you pull the latest release. You can download it manually or use tools like wget and curl. In this guide, I’ll use wget to download and install with dpkg -i commands. 

Download Desktop Dimmer binary:

As of this writing, the latest stable release is 4.0.4. It is recommended to first check releases before running below command.

$ wget https://github.com/sidneys/desktop-dimmer/releases/download/v4.0.4/desktop-dimmer-4.0.4-amd64.deb

Then install it on Ubuntu using

$ sudo dpkg -i desktop-dimmer-4.0.4-amd64.deb

Notice that I downloaded the 64-bit version. If your operating system has a 32-bit architecture, make sure you download i386 release. If by any chance you get dependency issues, you can resolve it using:

$ sudo apt-get -f install

This will ensure all missing dependencies are resolved and install Desktop Dimmer.
