10 things to do after installing Linux Mint 12

Linux Mint 12 (alias : Lisa) released, now it’s time to configure and install some mandatory applications/packages to start working on it. Although, Linux Mint 12 has already made the desktop little more user friendly, specifically for beginner users (who are coming from the windows(XP/Vista/7) world) but still there few things that you need to do for a complete usable – Linux desktop.

I’ve already published a post about 10 things to do after installing Ubuntu 11.10 and most of the tips should work seamlessly with Linux Mint 12 (as it is based on Ubuntu 11.10). Anyway, this post is supposed to help you in getting started on Linux Mint 12.

#1. Install restricted packages

First of all, you should install some proprietary codecs (audio/video/flash)and plugins (e.g Adobe flash player) and packages. These packages includes –

  • Adobe Flash Player plugin for browser
  • proprietary audio/video codecs (don’t you want to play mp3 songs?)
  • java runtime environment etc

So open terminal (Ctrl+Alt+t) and execute the command –

sudo apt-get install ubuntu-restricted-extras

If you want to play encrypted DVD then execute the following commands –

sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh

#2. Install VLC Player

VLC is the most popular – ‘all in one’ open source media player, specially good for playing various video files. VLC supports variety of input formtas including – flv, avi, ogg, mp4, mp3, wmv, wma. mkv, ogm etc. To install VLC media player in Linux Mint 12, fire up a terminal (Ctrl+Alt+t) and execute the command(s) –

Linux Mint 12 has Gnome Tweak Tool, installed by default, which allow you to configure advanced options for Gnome Shell desktop as well as for managing themes. To install icons, simply put the icon theme(downloaded packages) to ~/usr/share/icons directory. I’ve already covered a detailed post about installing Gnome Shell Themes on Linux Mint 12. (So you are supposed to refer the link)

#6. Install Ubuntu One

ubuntu-one in Linux Mint

Ubuntu One is a Dropbox like backup solution and the free plan offers 5GB storage which may be sufficient for a lot of users. Ubuntu One is well integrated with nautilus and so it will allow you to backup more easily. So whether you’ve used it earlier in Ubuntu or not, you should give it a try.

To install Ubuntu One execute following commands –

sudo add-apt-repository ppa:ubuntuone/stable
sudo apt-get update
sudo apt-get install ubuntuone-control-panel-gtk ubuntuone-client

#7. Configure GRUB options

grub-customizer

To customize grub menu or configure boot options there are two popular applications – startup manager (simple and easy to use) and second one is grub customizer (it has a lot of features and options).

customizing-grub-menu

Installing grub customizer,open terminal and execute –

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

On the other hand if you want to try startup manager, then execute –

sudo apt-get install startupmanager

#8. Install Ubuntu Software Center

ubuntu-software-center

If you have used Ubuntu Software Center in Ubuntu 11.10 or 11.04, then you might have noticed that on Linux mint there is another programs installed by default, for managing applications. Software Manager is the default program for installing/removing applications in Linux Mint, Synaptic Package Manager is also there. If you are missing some of the cool features of USC then you can install that in one simple command –

sudo apt-get install ubuntu-software-center

#9. Try MATE if you don’t like Gnome Shell

Gnome Classic - MATE

If you don’t like Gnome Shell interface, with a bunch of cool extensions then MATE is probably for your – for Gnome 2 lovers. MATE is a fork of Gnome 2 project, it looks very similar to Gnome 2.3 desktop. You can see (above screenshot of MATE) the Gnome 2 style menu in Top left corner of the screen – appears like Gnome 2. It’s installed by default – just logout from the current session and select Gnome classic (with or without effects, whatever suits your computer hardware).

#10. Install Bleachbit to clean up

Bleachbit is equivalent to CCleaner(of Windows). It will allow you to remove/delete unnecessary files from your computer, in a couple of clicks. To install bleachbit, simply execute the command –

Ubuntu 11.10 or Linux Mint 11 ?

I’ve been an Ubuntu user from last three years, (although I had tried a lot of other Linux distributions – including Linux Mint, OpenSuse etc, but Ubuntu has been my primary OS). I’ve written this post to collect your experience/thought/opinion related to Ubuntu and Linux Mint (it’s not an Ubuntu vs Linux Mint debate)

In the latest version of Ubuntu – 11.04 and 11.10 (released last month) – a lot of things has changed. Some of the changes seems innovative, exciting and revolutionary but most of the changes are annoying and unnecessary, in fact some design related changes are just different without any advantages over the previous design. Anyway – it’s what I think, if you have some comment about the recent changes in Ubuntu 11.10, Gnome 3 or Unity desktop, then please share your idea through comments.

ubuntu-11-10 with Unity
The frequent version release is another big problem with Ubuntu (in fact a lot of open source projects are the victim of version crap), stable version (which is achieved after a lot of bug fix) becomes outdated with the release of next version, the new and exciting features makes people shift to buggy – latest version and this continues. In other words –

stable version v is released
while(1)
{
Initially v is buggy and annoying
Most of the bugs are fixed in next few months
Now v is stable/usable/customized, but soon v+1 is announced with lot of exciting features/changes
We are looking for next version
v+=1
}

Linux Mint has been developed from Ubuntu and Debian based but it has some different strategy. It supports Gnome2 as well as KDE and XFCE. In later version(12) it will also supports Gnome 3 but you can still use Gnome 2 if you want – there is no compatibility problem. It focuses on usability and supports the things you expect. It is Linux based operating system, it is free of cost and available as an open source software – so you can customize it as you want. That’s why Linux Mint is now the 2nd most popular Linux distribution among desktop users.

Ruby Programming with Ubuntu 11.10

Ruby is one of the most popular scripting language. Ruby is an object oriented programming language, it’s open source, dynamic and cross-platform; it is well known for human friendly code. it has gained a lot of popularity (in past few years) in web world, probably due to the web application development framework – Ruby On Rails, that allow developers to build cool web applications very quickly. The same is true with Ubuntu (latest version 11.10 – Oneiric Ocelot) as it is now the most popular Linux distribution for desktop users.

Although this post isn’t going to teach Ruby but it will surely help you in getting started with Ruby, on Ubuntu 11.10 of course. Since Ruby is an interpreted language i.e source code itself is executed – line by line – by Interpreter. So first of all we need to install Ruby Interpreter.  The latest version of Ruby is 1.9.3 p0 (released on Oct 30, 2011), although 1.8.7 is also very popular as a number of applications are based on it.

If you want to quickly get started with Ruby then first install ruby 1.8.* or 1.9.* from command line or Ubuntu Software Center. Open a terminal (Ctrl+Alt+t) and execute –

sudo apt-get install ruby1.9.1

Then create a file ‘fun.rb’ and write a simple ruby program to test.

Creating a new file from terminal –

touch fun.rb

Then use a simple command line editor such as nano(or vim) or a gui gedit to put the code.

ruby program using nano

nano fun.rb
# This is a comment in Ruby!
puts "Enter something (Your Name or any number)"
some_thing = gets
puts "You said  #{some_thing}"

Then save the file (Ctrl+X => y => Enter, if you are using nano). Then you can execute the above ruby program (that simply get some input from the user and print it).

running-ruby-program

ruby fun.rb

Output :

Enter something (Your Name or any number)
just for Fun!
You said  just for Fun!

Recommended Link(s) for Learning Ruby/Ruby on Rails –

If you want to work with multiple versions of Ruby or wanna go ahead with Ruby and its libraries (called as RubyGems)or frameworks such as Ruby on Rails then you are recommended to use RVM (Ruby Version Manager) instead of installing ruby from Ubuntu Package Repository. I’ve already explained about RVM, Rails etc in detail (along with their dependencies) – install ‘Ruby on Rails’ in Ubuntu.
