This is Part 3 of the newbie's guide to operate Ubuntu 17.10. Here you'll learn most basic settings in Ubuntu divided in 2 parts (basics & installing applications) plus special part (GNOME Tweaks and Shell Extensions) at end. Basic needs such as changing wallpaper and enabling touchpad are explained with pictures, including repositioning the dock to bottom (many users will like it) and choosing repository mirror source too. I wish this simple tutorial helps you to operate Ubuntu fluently. This is the last part and I will republish them soon as an ebook. Enjoy!

SPECIAL PART


Special: Install GNOME Tweaks

Run command line below. With Tweaks, you can configure GNOME Shell desktop more like installing themes.
$ sudo apt-get install gnome-tweak-tool

GNOME Tweaks in action


Special: Install GNOME Shell Extensions

I've written tutorial for it here. Extensions extend your GNOME Shell desktop functionalities just like add-ons extend your Firefox, for example, adding timer/alarm or placing upload/download indicator at top panel. In short, how to do it:

  • Install the package:  sudo apt-get install chrome-gnome-shell
  • Install the Firefox add-on: download .xpi
  • Go to GSE website
  • Install any GSE you like (I recommend NetSpeed for first timers)
