How to Change Nautilus Background Color in Ubuntu 13.04

Last updated: September 12, 2013

This simple tutorial shows you how to change the Nautilus file browser and other apps’ background & selected color if you’re boring with the default colors in Ubuntu 13.04 Raring.

It can be easily done in Nautilus 3.4.x and 3.6.x via Dconf Editor. So this tutorial will also work for Ubuntu 12.10 Quantal and Ubuntu 12.04 Precise.

In the screenshots below, I changed the background color to sky blue and selected color to black.

To do it, open Dconf Editor from Unity Dash. Navigate to org/gnome/desktop/interface, add or change the value of gtk-color-scheme. So that you can change the background color, tooltips color, text color, etc.

bg_color:#C4E5F6;selected_bg_color:#000000;base_color:#888888;tooltip_fg_color:#ffffff;tooltip_bg_color:#ffffff;text_color:#000000

To restore, just remove what you added. Enjoy!

Last updated: September 10, 2013

Want to block access to certain websites from your machine running Ubuntu or Linux Mint? It’s easy to do it by editing the host file.

With the hosts file, you can tell Ubuntu to redirect the specific websites to 127.0.0.1. So that the web browser returns below error:

To do so, edit the /etc/hosts with your favorite editor. Press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run below command to edit the hosts via gedit:

sudo gedit /etc/hosts

Add below lines to the end of the file. Exclude the “http://” and change the domain names.

# block access to certain sites
127.0.0.1 www.websites1.com
127.0.0.1 www.websites2.com
127.0.0.1 websites3.com
127.0.0.1 morewebsites.com

Save the file and re-launch your web browser. Done.

How to Watch Live Streams on Ubuntu via Your Favorite Video Player

Last updated: September 8, 2013

Want to watch live streams on Ubuntu via your favorite video player? Well, here’s how to do it using Livestreamer which supports most of the big streaming services such as Dailymotion, Livestream, Twitch/Justin.tv, YouTube Live, UStream.

Livestreamer is a Command Line Interface that pipes video streams from various services into a video player, such as VLC, Mplayer. The main purpose of Livestreamer is to allow the user to avoid buggy and CPU heavy flash plugins but still be able to enjoy various streamed content.

There is also an API available for developers who want access to the video stream data.

It’s very easy to use this tool. Let’s say you want to watch the stream located on http://twitch.tv/day9tv, just run below command in terminal (press Ctrl+Alt+T to open it).

livestreamer twitch.tv/day9tv

[cli][info] Found matching plugin justintv for URL twitch.tv/day9tv
Found streams: 240p, 360p, 480p, 720p (best), mobile_high, mobile_low (worst)

It will find out what streams are available and print them out for you to choose from. Simply give livestreamer the stream as the second argument and playback will start in your video player of choice.

In this case the best stream is a reference to the stream that is considered to be of highest quality, e.g 720p. The –player argument will specify the video player (It will open VLC as the default player if not specified).

livestreamer twitch.tv/day9tv best --player mplayer

Install Livestreamer in Ubuntu, Linux Mint

Press Ctrl+Alt+T on your keyboard to open terminal. When it opens run below commands to install pip installer:

sudo apt-get install python-pip

Then install Livestreamer via pip:

sudo pip install livestreamer

This will work on all current supported Ubuntu releases, include Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04, Ubuntu 10.04 and their derivatives such as Linux Mint and Elementary OS.
