Manjaro Post Install Guide

July 25, 2018

Manjaro is my distribution that I choose for development environment, works quite well in my old Asus ROG G75VW, before Manjaro used Ubuntu 16.04 that I loved but their packages were somewhat old and I wanted to try Plasma 5 but not with distributions that came from Debian.

The option was clear and easy, Arch was what most suited for me. Previously I had tried Arch but I did not like that I had to spend days configuring my laptop to had everything I need to work. I had never tried Manjaro, I knew it was derivative from Arch but I was not sure that he would work well on my computer.

I tested Manjaro with Plasma 5 and I love it! run pretty fast and smooth, work out of the box, easy Nvidia drivers installation and so on.

By default Manjaro has many many packages that I used to install on Ubuntu after install, no more with Manjaro this saves me lot of time.

So, no more talk. This is my configuration for set a basic Ruby on Rails development environment.
