Install Cinnamon Desktop in Ubuntu
A desktop domain is an accumulation of instruments which empower the client to perform errands on their PC.
The desktop condition comprises of various key segments, for example, the window administrator, which decide how windows show up and carry on, a menu, a board which is otherwise called an undertaking bar, symbols, document chiefs and different devices which essentially make it workable for you to utilize your PC.
On the off chance that you originated from a Microsoft Windows foundation then you will just truly remember one desktop condition as there is just the default one accessible.
In Windows 10 there is a board at the base of the screen with the Windows logo in the base left corner and a check and framework plate in the base right. Tapping on the Windows logo raises a menu from which you can dispatch applications. You can likewise click symbols on the desktop.
Inside Windows you can drag windows, resize them, put them on top of each other and snap them one next to the other. Windows can likewise be limited and boosted.
These things basically make up what is thought to be a desktop domain.
Ubuntu of course accompanies a desktop domain called Unity. The key qualities are the dispatch bar on the left half of the screen, a board at the top and when you press the top symbol on the dispatch bar a dash interface shows up where you can discover applications, play music and watch recordings.
Cinnamon is the default desktop condition for Linux Mint. Linux Mint depends on Ubuntu and has a large portion of similar components.
The Cinnamon desktop is a great deal a bigger number of Windows-like than the Unity desktop that accompanies Ubuntu.
On the off chance that you haven’t introduced Ubuntu yet and you would favor your desktop to capacity more like the Windows one then I would recommend really introducing Linux Mint as opposed to Ubuntu as Cinnamon has as of now been redone to work splendidly.
On the off chance that anyway you have as of now introduced Ubuntu then there is no compelling reason to go to the inconvenience of making a Linux Mint USB drive and supplanting your Ubuntu working framework with Linux Mint. This is pointless excess.
You may likewise need to utilize Ubuntu and not Linux Mint as it is constantly in front of Linux Mint as far as improvement. Linux Mint bases itself on the long haul bolster arrival of Ubuntu. Fundamentally this implies you get adaptation 16.04 of Ubuntu in addition to and security updates and bundle refreshes yet you don’t get more current components offered by Ubuntu 16.10 or surely later.
In view of this you may like to utilize Cinnamon on Ubuntu than on Linux Mint.
Notwithstanding with respect to why you have introduced Cinnamon on Ubuntu this guide will demonstrate to you proper methodologies to introduce the most recent form of Cinnamon and also include some valuable changes toward the end.
Install Cinnamon From The Ubuntu Repositories
The variant of Cinnamon in the Ubuntu standard vaults is not the most recent adaptation accessible but rather it is sufficient for the vast majority’s needs.
In the event that you need to introduce the extremely most recent adaptation perused on as this will be secured later on.
In any case with regards to the variant you wish to utilize I prescribe introducing Synaptic so it is less demanding to discover and introduce Cinnamon. Synaptic will come in exceptionally helpful for different undertakings, for example, introducing Java.
Keeping in mind the end goal to introduce Synaptic open a terminal window by squeezing CTRL, ALT and T in the meantime.
Enter the accompanying summon:
sudo well-suited get introduce synaptic
You will be made a request to enter your secret key to proceed.
To dispatch Synaptic tap on the top catch on the Ubuntu dispatch bar and enter “Synaptic” into the hunt box. Tap on the “Synaptic” symbol.
On the off chance that you are glad to introduce the variant of Cinnamon in the Ubuntu archives tap on the inquiry catch and enter “Cinnamon” into the crate.
Discover the choice called “Cinnamon-Desktop-Environment” and place a tick in the crate by it.
Install The Latest Version Of Cinnamon On Ubuntu
Keeping in mind the end goal to utilize the most recent form of the Cinnamon desktop condition you should include an outsider “Individual Package Archive” (PPA) to your product sources.
A PPA is a vault made by a man, gathering or organization and is not connected to the Ubuntu designers.
The upside to utilizing a PPA is that you get the most recent variant of the bundles yet the drawback is that they aren’t bolstered by Ubuntu.
With a specific end goal to introduce the most recent form of the Cinnamon desktop condition take after these means:
- Open the Synaptic Package Manager by tapping on the top symbol on the desktop and entering “Synaptic” into the inquiry bar. In the event that you haven’t introduced Synaptic allude to the past slide
- Tap on the “Settings” menu and pick “Stores”
- At the point when the “Product and Updates” screen shows up tap on the “Other Software” tab
- Tap the “Include” catch at the base of the screen
- Glue the accompanying into the case gave ppa:embrosyn/cinnamon
- When you close the “Product and Updates” shape you will be made a request to reload from the archives. Click “Yes” to pull in the greater part of the product titles from the PPA you just included
- Click “Look” at the highest point of the Synaptic window and enter Cinnamon
- Put a tick in the case called “Cinnamon”. Take note of that the form ought to state 3.2.8-yakkety and the portrayal ought to state “Present day Linux Desktop”.
- Click “Apply” to introduce the Cinnamon desktop and enter your secret word when required to do as such
The most recent variant of Cinnamon ought to now be introduced
Boot Into The Ubuntu Cinnamon Desktop
To load the Cinnamon desktop that you have just installed either reboot your computer or logout of Ubuntu.
When you see the login screen click on the white dot next to your name.
You should now see the following options:
- Cinnamon
- Cinnamon (Software Rendering)
- Ubuntu (Default)
- Unity8
Click on the Cinnamon option and then enter your password as usual.
Your computer should now boot into the Cinnamon desktop.

UBUNTU 18.04 LTS TO USE GNOME BY DEFAULT
UNITY 8 AND THE PHONE TO BE DISCONTINUED
Ubuntu 18.04 LTS will go back to using GNOME as the default desktop environment, instead of Unity.
While Mark doesn’t explicitly says “GNOME Shell”, I assume that’s what he means, especially since Unity 7 has been in maintenance mode for quite a few Ubuntu releases.
“I took the view that, if convergence was the future and we could deliver it as free software, that would be widely appreciated both in the free software community and in the technology industry, where there is substantial frustration with the existing, closed, alternatives available to manufacturers. I was wrong on both counts.
In the community, our efforts were seen fragmentation not innovation. And industry has not rallied to the possibility, instead taking a ‘better the devil you know’ approach to those form factors, or investing in home-grown platforms. What the Unity8 team has delivered so far is beautiful, usable and solid, but I respect that markets, and community, ultimately decide which products grow and which disappear”.

Ben Burns' NHL Notebook (November 22)
After recently losing a game in which the team I selected dominated play and doubled it's opponent's total number of shots, I received an email asking me what is the most important ingredient necessary to win in today's NHL.
I responded by saying that I did not have a definitive answer. Obviously, the key to winning is outscoring the opposition. However, pinpointing a single specific factor which enables a team to score more goals than its opponent is not so obvious.
Is it more important to score the most goals or to allow the few? Is it more important to have the best penalty-killing or to have the best power-play? How relevant are shots on goal?
Let's take a closer look at the top-10 teams in a number of statistical categories and see if we can answer some of the above questions and determine the secret formula for success.
GOALS
Team Goals Per Game League Rank (Total Points)
Ottawa * 4.7 2
Philadelphia 4.4 9
Colorado 4.0 13
Los Angeles 3.8 4
Toronto 3.7 11
Detroit 3.6 1
Carolina 3.6 3
Dallas 3.6 10
Atlanta 3.6 26
Buffalo 3.4 17
* Note: The Sens would have the most points but have played fewer games than most teams
GOALS AGAINST
Team Allowed Per Game League Rank
Ottawa 2.1 2
Minnesota 2.4 19
Detroit 2.5 1
NY Rangers 2.5 6
Phoenix 2.6 14
Calgary 2.6 12
Nashville 2.7 8
Los Angeles 2.9 4
Carolina 2.9 3
Vancouver 2.9 7
Anaheim 2.9 24

Ottawa 1.28 2
New Jersey 1.25 20
Vancouver 1.24 7
Montreal 1.24 5
Pittsburgh 1.24 25
POWER-PLAY GOALS ALLOWED

Minnesota 0.65 19
New Jersey 0.80 20
Tampa Bay 0.82 16
NY Rangers 0.87 6
Buffalo 0.90 17
Colorado 0.90 13
Los Angeles 0.90 4
Detroit 0.91 1
Nashville 0.94 8
San Jose 1.00 21
Ottawa 1.00 2
There are many other statistics I could have analyzed, including goaltending, power-play conversion percentage, the percentage of shots and / or power-plays converted, and the percentage of penalities killed, to name just a few.
Still, I feel that those results would have demonstrated the same conclusion. There is not necessarily a single factor which has the largest impact on success in the NHL.
One dimensional teams, like the defensive-minded Minnesota Wild or the offensive-minded Atlanta Thrashers, can be competitive. However, the best teams in the league, like the Ottawa Senators and the Detroit Red Wings, are extremely balanced and perform well in virtually all facets of the game.
Reset Ubuntu To Factory Default
Today, I have come up with a news about a wonderful tool called Resetter, which is used to reset Ubuntu to factory defaults. That means, your Ubuntu system will go back to the state when you installed it in the first time. It finds all applications which are installed after Ubuntu fresh installation and delete them. Not just applications, it also deletes the users too. You don’t have to install everything from the beginning. Just reset your Ubuntu to its factory defaults and start installing everything else. Don’t worry about your data. Resetter won’t touch your data. It just removes the applications and the users. To put this simply, It will detect and remove packages that have been installed after the initial system install.
Resetter completely free and open source. It is built with python and pyqt. It is not just for Ubuntu alone. It will work on Ubuntu derivatives like Linux Mint. It currently supports the following distributions.
- Linux Mint 18.1
- Linux Mint 18
- Linux Mint 17.3
- Ubuntu 17.04 (coming soon)
- Ubuntu 16.10
- Ubuntu 16.04
- Ubuntu 14.04
In this brief guide, I will explain how to install and how to use Resetter to reset Ubuntu system to its factory settings.
Install Resetter
Download the latest version from the GitHub page (The link is attached at the end).
wget https://github.com/gaining/Resetter/archive/master.zip
Extract it using command:
unzip master.zip
This command will extract all contents into a folder called Resetter-master in your current working directory. Go to this directory and install it like below.
cd Resetter-master/
sudo dpkg -i resetter_0.0.2-beta_all.deb
Reset Ubuntu To Factory Defaults
Once installed launch it either from Unity dash or Menu.
The default interface of Resetter will look like below.
As you see, it has two options namely “Automatic Reset” and “Custom Reset”.
Automatic Reset (Not Recommended)
As the name implies, Automatic Reset will reset your Ubuntu system completely to its factory defaults automatically. It detects all applications which are installed after Ubuntu fresh installation and delete them including the Users. If you don’t care much about your Ubuntu system, You can use option to wipe every applications installed after Ubuntu fresh installation.
Click Automatic Reset to proceed.
Please BE MINDFUL that this option will remove all applications including the users after Ubuntu fresh installation. Also, it will create a new user called “default” automatically.
Click OK to continue.
If you want to keep any applications from removal, just uncheck them.
Now, Resetter will detect and delete all applications including the existing users.
After few minutes, it will automatically create a new user. You need to use these credentials the next time you log in.
Finally, reboot your Ubuntu system.
Now, log in with new user credentials.
Congratulations! Your Ubuntu system has been reset to its factory defaults. Start installing the applications you want to use.
Custom Reset (Recommended option)
This is the recommended method. Using this option, you can decide which applications to remove and which applications to keep. Also, you can have an option to keep your existing user or create a new user of your choice. The automatic method doesn’t allow you to create your own user of your choice. It will simply delete the existing user and create an user called ‘default’.
Click Custom Reset button in the Resetter home screen. Choose the applications to remove.
Next, you will be asked whether you want to remove or keep the existing. You can choose whether you just want to remove the user or user with its home directory. Be careful while you choosing this option. If you choose the option that labeled “Choose User and Home”, all data on your HOME directory will be deleted.
Click Finish button to apply the changes.
Click Yes to create your own new account. Or, click No to to create a default account.
Enter the username and password of your choice if you had chosen Yes in the previous wizard.
Now, Resetter will find and delete all applications/users installed/created after Ubuntu fresh installation.
Once its done cleaning, it will show you the user credentials to use to login next time.
Finally, select Yes to reboot your Ubuntu system.
Done! Log in with your new user and start using it.
Resetter is still in beta stage, but it is fully functional. One problem I have faced while testing this app is it doesn’t let me to log-in to my Ubuntu box when I use Automatic Reset option. Even though, I have used the correct credentials, It kept saying the password is wrong. I don’t know why. But, everything works fine in Custom Reset method.
If you messed up with your Ubuntu system, Resetter will give you an easy way to reset Ubuntu to its initial state. You don’t have to re-install Ubuntu. It really deserves a space in your arsenal. Give it a try. You won’t be disappointed.
Cheers!
