30 things to do after installing Ubuntu 18.04

30 things to do after installing Ubuntu 18.04

Ubuntu is perhaps the most popular Linux distribution on the planet. This is due to ease of use and a large number of programs available, but it is always possible to improve its user experience. That’s why I will show you these 30 things to do after installing Ubuntu 18.04.

You can watch the video tutorial or continue reading below.

Video tutorial

1. Configure the update manager and repositories

In the first place, you must configure the software sources from which APT will take the packages that will be downloaded to your Ubuntu.

If you go to the application menu and search for updates, you will see this Software & Updates manager. Open it.

Launching Software options

Launching Software and Updates Options

You should have the main, universe, restricted and multiverse options active but not the source code. These are the official Ubuntu repositories.

Software and Updates window

Software and Updates window

In the installation, Ubuntu selects the default server in your country to download updates, but not necessarily the fastest. However, you can switch to the fastest repository mirror.

Click on Download from, then on other, and finally on Select Best Server.

Choosing the best server for downloading the packages

Choosing the best server for downloading the packages

After the test is done, select the recommended server. To apply the change, you need to enter your administrative password. Now, you will be downloading the updates from the fastest server.

Next, I recommend enabling the repository of Canonical partners. Click on the Other Software tab and check Canonical partners.

Select Canonical Partners repository

Select Canonical Partners repository

Then, in the Updates tab, you can configure what to update and how often to check for updates. I do not recommend making changes in this section.

Checking the frequency of searching for updates

However, I recommend to sing up for livepatch, which is a technology developed by Canonical to allow installing Kernel security patches without the need to reboot the system. With this intention, you just have to click on the Sign in button and enter our Canonical account data. If you don’t have one, you can create it there.

Finally, you can now run the Software Updater from the launcher and install all the updates.

Installing the Ubuntu Updates

Installing security updates

When you have finished installing security updates and patches, restart your operating system.

2. Install Drivers

After Installing Ubuntu 18.04, you can install drivers from the same Software & Update application. Go to the Additional Drivers tab and wait for some time while the program is analyzing your system. If you have any proprietary hardware, it will show you options for installing it. Install any suitable drivers. When finished, you need to restart the system.

Installing Additionals Drivers

After Installing Ubuntu 18.04 it is prudent to install additional Drivers

3. Install Synaptic package manager

Synaptic is a grephical package manager that uses APT. It is not the most user-friendly package manager, but it is extremely reliable. Unfortunately, Ubuntu Software Center doesn’t work well all the time. In other words, Synaptic is a “rock”.

Search for Synaptic in your launcher and there should be an option to install it.

4. Install additional codecs, MS fonts, flash, and a few more useful packages

To be able to play all video and music formats, you need to install ubuntu-restricted-extras package. I will use Synaptic this time.

Open Synaptic, and in the Search field, type ubuntu-restricted-extra. Next, mark it for installation with right mouse button.

Installing ubuntu-restricted-extra packages using synaptic

If you are going to play DVD, then install this DVD library libdvd-pkg as well.

If you need to run Java applications, search for opejdk-8-jre and openjdk-8-headless packages and install them too.

You can keep searching and installing as many packages as you want. When you’re done, click Apply.

However, during the installation the libdvd-pkg package must be configured from the terminal. Copy that command that appears during the installation process as in the image above, and once the whole installation process is over, open a terminal and run it.

sudo dpkg-reconfigure libdvd-pkg

I also recommend you to install the apt-xapian-index package, which is a quick search engine for Synaptic.

5. Install microcode

Microcode is the firmware for your processor, it is recommended to install for better performance and to receive the processor firmware updates. It is good to have it on your system.

Open Synaptic, and search for microcode. You will see two options: intel-microcode and amd64-microcode; you must choose according to your processor. I have an Intel processor, that’s why I will install the intel-microcode package.

Installing intel-microcode package rfom synaptic

Installing intel-microcode package from Synaptic

6. Activate minimize to Dock

If you click on the icon of any application in the dock, it will not minimize. There are two ways to fix this issue: one through the command line interface and another in a graphical way.

Through the command line interface, you only have to open a terminal and run:

gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'

To do this graphically, you must install the dconf-editor package through Synaptic.

Installing dconf-editor package

Installing dconf-editor package

Once installed, open Dconf Editor go to org -> gnome -> shell -> extensions -> dash-to-dock. Scroll down until you find click-action. Here, you switch off the default value and select minimize.

Using dconf-editor to modify dash to dock behavior

Using Dconf Editor to modify Dash to Dock behavior

After this, when you click on the icon of any application in the dock, it will minimize and on the second click maximize. This is way better than the default behavior.

7. Decrease Swap Use

Swap is the space on your hard drive that is used to store the data when there is not enough RAM. It’s faster than your hard drive, so it is better to use it at maximum. By default, Ubuntu has a balance swapiness value of 60, but you can force the system to use as much RAM as possible and write to the disk only when most of the RAM is in use.

If you want to check your swapiness value, run in a terminal:

cat /proc/sys/vm/swappiness

Next, edit the default value:

gedit admin:///etc/sysctl.conf
Checking the value of Swappiness

Checking the value of swappiness

You must enter your password. Scroll down the file and in the end, add:

vm.swappiness = 10
Editing the Swappiness

Editing the swappiness

Save the changes and finally restart your computer. Now, you Ubunut will start writing files from RAM to a hard drive only when the RAM use reaches very high level.

8. Enable Drive Cache

Usually, the program waits until the data is written to the disk and it proceeds to the next step only after the write event. However, you can force your programs to cache the data and write it to the disk with some delay.

For the purpose of enabling the hard drive cache, go to the menu and search for the Disks application and open it.

Running Disk application

Running Disk application

Select the disk where Ubuntu is installed. Open the menu and select Drive settings. Then, go to the Write cache tab and enable it.

Enabling Drive Cache

Enabling Drive Cache

This should slightly improve the performance of your hard drive.

9. Reduce SSD Writes

There are two things that are necessary for good performance and a longer lifespan of an SSD drive. The first thing is Trim and the second is to reduce write cycles.

Ubuntu 18.04 already has trim enabled, so there’s no need to do anything.

However, the write to SSD cycles is not reduced by default. But, there is an option to unable very easy.

Execute in the terminal:

gedit admin:///etc/fstab

Find your SSD partitions, likely it is the partition that has sda in its name. Find the right partitions based on their size. And add noatime before the word errors. But DON’T do it for the Swap partition.

Adding noattime option on fstab file

Adding noattime option on fstab file

Save and close the file. Write to SSD cycles are reduced.

10. Set up Firewall

Ubuntu is already very secure and activating a firewall is not an essential security measure. However, it is better to be extra safe and the firewall doesn’t use many resources of your system.

Open Synaptic and install the gufw package.

Installing gufw package

Installing gufw package

Once installed, open it. During its launch, you will be prompted for your password.

Running gufw from menu

Running gufw from the menu

The settings are very simple here. You just need to enable it. This should be fine for the most of the users.

GUFW is enabled

GUFW is enabled

Although if you needed to make a new rule, click on the plus button. For example, you may want to use KDE connect, select Allow, Both Directions and in the applications select KDE connect.

The process is the same with the rest of the applications.

11. Configure Ubuntu settings

In this section, I will configure a few things after installing Ubuntu 18.04 to improve the desktop experience.

Ubuntu Dock

In a first place, I will configure Dock. Select Dock in the Ubuntu Settings:

12. Move Applications menu in Dock

When the Ubuntu dock is at the bottom, the location of the application menu is not the most convenient. I suggest to move it to the left.

The location of the application menu is not the most convenient

The location of the application menu on the far right is not the most convenient

First, open dconf Editor.

And your Applications button is at a much more convenient place now.

13. Install GNOME Tweaks

If you want to modify GNOME, you need to install GNOME Tweaks to improve the experience after installing Ubuntu.

Search for gnome-tweak-tool in Synaptic.

16. Install additional themes

Ubuntu is a very customizable operating system, that is, you can install many themes and change Ubuntu’s appearance.

First, you have to install User Themes GNOME Shell extension from the web.

Installing "User theme" extension

Installing “User theme” extension

Now, you can install other themes, for example, install Flat Remix theme. One of the most popular themes. Open Synaptic, go to the settings of the repositories. Then, other software tab and here click add and paste this repository address.

You can read a more detailed post about how to customize themes, icons, and layouts of Ubuntu 18.04.

17. Change Firefox Settings

Firefox is the default browser in Ubuntu and many Linux Distributions. It stands out for being open source and it also is customizable in many many ways. However, in this case, I’ll show you two things I always do to improve the browser experience.

First, Open Preferences, in the section, When Firefox starts, enable Show windows and tabs from last time. With this option every time Firefox starts, it will show the tabs you had open before closing it.

Selecting "Show windows and tabs from last time" from Firefox preferences

Selecting “Show windows and tabs from last time” from Firefox preferences

Next, click on the Firefox main panel and select customize. And add search field. This search field will be very useful if you want to search in Google an email address because if you type it in the direction bar, it will open the email application that the system has by default.

21. Schedule Backups

It is a good idea to make backups of the system in order to preserve our documents and files that you do not want to lose. Ubuntu already has a simple backup program. Open it from the menu.

102.- Launching Ubuntu Backup Tool

102.- Launching Ubuntu Backups Tool

In the Folders to Save section, you can define what folders to back up. For example, I will back up the Documents folder.

Ubuntu Backup tool

In Storage Location you can choose where you want to back up. You can use Google Drive, Nextcloud, Network Server, or a local folder.

Choosing where to save the backup

If you configured online account or your local storage is permanently connected to your computer, it makes sense to configure the backup schedule.

The program will ask to install additional packages. Install them.

You can also encrypt your backup with a password.

After these few steps, automatic backup is configured. If you want to be little more advanced, you can also make backups with rsync.

22. Remove unnecessary software

Removing unnecessary programs is a good way to save space on your hard drive, so it’s a good thing to do. Open the Software Center. Go to installed applications and uninstall all programs you don’t need. For example, I uninstall all the games.

Uninstall unnecessary software from Center Software

Uninstall the unnecessary software from Center Software

If you are an experienced Linux user, you can remove even more packages through the Synaptic package manager. For example, you can remove Bluetooth packages if you don’t have a Bluetooth.

But be very very careful. You may uninstall some crucial packages as dependencies. So, if you are unsure, do not remove anything from Synaptic.

23. Turn off startup applications

You can define which applications you want to run at system startup. Search for Startup Applications in the menu and open it. As you can see there aren’t many applications. This is because most of them are hidden.

Startup Applications in Ubuntu 18.04

Startup Applications in Ubuntu 18.04

To show all startup applications in Ubuntu, run this command in the terminal.

sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

Running a command to show hidden applications

Now, as you can see your system is loaded with startup applications.

All programs that run at system startup.

All programs that run at system startup.

You can disable some of them if you don’t need them. For example, I disable Orca screen reader.

Disabling some startup programs

Disabling some startup programs

Remember, if there are fewer applications running at startup, the system will boot faster. However, if you are not sure which applications to disable, leave them that way to avoid creating instabilities.

24. Clean system (Bleachbit)

An operating system with the time of use begins to fill with useless files. To keep your system clean, you can install Bleachbit. Open Synaptic and search for bleachbit package.

Installing Bleachbit from Synaptic

Installing Bleachbit from Synaptic

When the installation is complete, open it. You can do some setting here. For example, the whitelist will be very useful if you don’t want to remove files form specific location ever.

Bleachbit white list

Bleachbit whitelist

In the panel located on the left side, you choose what you want to clean. In a first place, it is a good idea to select all APT options. APT is a software manager backend. You can also delete cookies from your browser as well as the cache of installed applications.

Cleaning some cache packages

Next, perform this cleaning.

Reviewing the system cleaning process with Bleachbit

Reviewing the system cleaning process with Bleachbit

You can see how much space has been cleaned. If you see Permission denied errors when running Bleachbit, it is because to perform these tasks with the packages Bleachbit needs root user privileges. To fix this error, run Bleachbit as a root user. Go to Menu and open Bleachbit (as root).

Launching Bleachbit as root user

Launching Bleachbit as root user

And perform APT cleaning again. Now, it worked.

As I said, it is important to clean the system from time to time in order to have space on your hard disk and make the system faster.

25. Install VLC

VLC is probably the best video player not only in Linux but even in Windows and Mac. It plays all formats and it has a simple interface. Moreover, you can even extract images form video with VLC and them make a GIF from them.

VLC is so good that it is practically obligatory to install it. You can install through Synaptic, but I want to show you another graphical way to install programs in Ubuntu. You probably didn’t know about it.

Type in your browser: apt://vlc. Press enter. Select AptUrl.

Installing VLC from web browser using AptURL

You can see in the description what is going to be installed. Install VLC.

With VLC you can get the incredible flexibility to play multimedia files. If you want, you can modify its appearance. It also has an equalizer that you can adjust as you like. VLC even has some less know features.

26. Install Google Chrome

I know that some users prefer Chrome over Firefox. There are some valid reasons for this. To install it go to Google Chrome website.
