How to change system language in Manjaro xfce

In order to change language, the Manjaro setting manager has to be installed

To download the Manjaro setting manager, open a terminal and run:

pacman install manjaro-settings-manager

sudo pacman -S manjaro-settings-manager

It should now be installed, confirm by searching for it by typing "Manjaro setting Manager in the search bar.

Adding other languages to the settings: 

1. Go to File System

2. Right-click File System and select Terminal

3. Once the terminal opens, run:

ls

cd etc

4. Open up the file "locale.gen" by running:

sudo nano locale.gen

add the following lines:

it_IT.UTF-8 UTF-8

it_IT ISO-8859-1

it_IT@euro ISO-8859-15

To save and exit:

control o enter

control x 

This will add the Italian language, to add other languages just add your countries code in the file instead. Look up your code here.

Once you open up the Manjaro setting manager again you should see your language as an option!
