Setting up a Spanish Keyboard on my Chromebook's Lubuntu

Today I learned this easy and useful trick thanks to Longtom, at PCLOS Forum!

1. Go to Menu > File Tools > File Manager Super User
2. In the address bar type  /etc/xdg/lxsession/LXDE/
3. Open the file “autostart” and add the following :
    setxkbmap -layout "za,us"
4. Save the file, log out and log in

All I had to do was replacing "za" with "es" and that did the trick:

A test sentence: La pequeña niña está dibujando un corazón. 

THANKS A LOT!!!
