This article introduces the relevant knowledge of "what to do after installing Ubuntu20.04". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

16 things to do after installing Ubuntu 20.04 LTS "Focal Fossa"

The steps I mentioned here are only my suggestions. If some customizations or adjustments do not suit your needs and interests, you can ignore them.

Again, some of the steps seem simple, but are necessary for a novice to Ubuntu.

Some of the recommendations here apply to enabling GNOME as the default desktop Ubuntu 20.04, so check the Ubuntu version and desktop environment.

The following list is what to do after installing Ubuntu 20.04 LTS codenamed Focal Fossa.

Prepare your system by updating and enabling additional software repositories

After installing Ubuntu or any other Linux distribution, the first thing you should do is update it. Linux operates on a local database of available packages, and this cache needs to be synchronized so that you can install the software.

Upgrading Ubuntu is very simple. You can run the software update from the menu (press Super and search for "software updater"):

You can also update your system at the terminal with the following command:

Sudo apt update & & sudo apt upgrade

Next, you should make sure that universe (Universe) and multiverse (Multiverse) software repositories are enabled. Using these software repositories, you can access more software. I also recommend reading articles about Ubuntu software repositories to understand the basic concepts behind it.

Search the menu for "Software & Updates":

Software and update settings

Be sure to select the check box in front of the software repository:

Enable additional software repositories

2. Install a media decoder to play MP3, MPEG4 and other format media files

If you want to play media files, such as MP3, MPEG4, AVI, etc., you need to install a media decoder. Due to copyright issues in various countries, Ubuntu does not install it by default.

As an individual, you can easily install these media codecs using the Ubuntu Restricted Extra installation package. This will install media codecs, Adobe Flash players and Microsoft True Type fonts on your Ubuntu system.

You can install it by clicking this link (it will ask to open it in the Software Center), or use the following command:

Sudo apt install ubuntu-restricted-extras

If you encounter the EULA or license interface, please remember to use the tab key to select between options, and then press enter to confirm your choice.

Press tab to select OK and press enter

3. Install software from the software center or network

Now that you have set up the software repository and updated the package cache, it is time to install the required software.

There are several ways to install an application in Ubuntu, and the easiest and most formal way is to use a software center.

Ubuntu Software Center

If you want some advice on software, please refer to this rich list of Ubuntu applications for various uses.

Some software vendors provide .deb files to easily install their applications. You can get .deb files from their website. For example, to install Google Chrome on Ubuntu, you can get the .deb file from its website and double-click it to start the installation.

4. Enjoy games on Steam Proton and GameModeEnjoy

Playing games on Linux has come a long way. You are no longer limited to the few games you bring. You can install Steam on Ubuntu and enjoy many games.

Steam's new Proton project allows you to play a lot of Windows-only games on Linux. In addition, Feral Interactive's GameMode is installed by default in Ubuntu 20.04.

GameMode automatically adjusts the performance of the Linux system to give the game a higher priority than other background processes.

This means that some games that support GameMode, such as Tomb Raider rise, should improve their performance on Ubuntu.

5. Manage automatic updates (for advanced users and experts)

Recently, Ubuntu has started automatically downloading and installing security updates that are critical to your system. This is a security feature, as an ordinary user, you should keep it on by default.

However, if you like to do configuration updates yourself, and this automatic update often causes you to "cannot lock the administrative directory" error, you may be able to change the automatic update behavior.

You can choose "Show now" so that you will be notified as soon as there is a security update instead of automatically installing it.

6. Control the automatic hang and screen lock of the computer.

If you use Ubuntu 20.04 on your laptop, you may need to pay attention to some power and screen lock settings.

If your laptop is in battery mode, Ubuntu will hibernate after 20 minutes of inactivity. This is done to save battery power. Personally, I didn't like it, so I banned it.

Similarly, if you leave the system for a few minutes, it will automatically lock the screen. I don't like this behavior either, so I'd rather disable it.

7. Enjoy the night mode

One of the most closely watched features in Ubuntu 20.04 is night mode. You can enable night mode by entering the settings and selecting it in the appearance section.

Open the night theme Ubuntu

You may need to make some additional adjustments to get the full Ubuntu 20.04 night mode.

8. Control desktop icons and launch programs

If you want the simplest desktop, you can disable the icon on the desktop. You can also disable the startup program from the left and disable the software status bar in the top panel.

All of this can be controlled by the default new GNOME extension, which is already available by default.

By the way, you can also change the position of the startup bar to the bottom or right by setting-> appearance.

9. Use emoji and special characters, or disable it from search

Ubuntu provides an easy way to use emoticons. By default, there is a dedicated application called character. It can basically provide you with emoji Unicode.

Not only emoticons, you can also use it to get unicode for French, German, Russian and Latin characters. Click on the symbol you can copy the unicode, and when you paste the code, the symbol of your choice is inserted.

You can also find these special characters and emoticons in desktop search. You can also copy them from search results.

If you don't want to see them in the search results, you should disable the search function's access to them. The next section will discuss how to do this.

10. Master desktop search

The GNOME desktop has powerful search capabilities, and most people use it to search for installed applications, but it's not limited to that.

Press the Super key and search for something, and it will display any application that matches the search term, followed by the matching application provided by the system settings and the software center.

Desktop search

Not only that, the search can also find the text in the file. If you are using a calendar, it can also find your meetings and reminders. You can even do a quick calculation in a search and copy the results.

Fast Computation of Ubuntu search

You can go to Settings to control the content and order in which you can search.

11. Use night light function to reduce eye fatigue at night

If you use a computer or smartphone at night, you should use the night light function to reduce eye fatigue. I think it's very helpful.

The night light is characterized by the addition of a yellow hue to the screen, which is less crowded than white light.

You can switch to the night light tab in Settings-> display to turn on the luminous function. You can set the "yellowness" according to your preference.

12. Use a 2K/4K monitor? Use resolution zoom to get larger icons and fonts

If you think icons, fonts, and folders look too small on your high-resolution screen, you can use the resolution to zoom.

Enabling resolution scaling gives you more options to increase from 100% to 200%. You can choose the zoom size that suits your preferences.

Enable high score zooming in Settings-> display

13. Explore GNOME extensions to extend GNOME desktop availability

GNOME desktops have small plug-ins or add-ons called extensions. You should learn to use GNOME extensions to extend the usability of the system.

As shown in the following figure, the weather information is displayed in the top panel of the weather extension. Humble but very useful. You can also check out some of the best GNOME extensions here. You don't need to install them all, just use those that are useful to you.

14. Enable "do not disturb" mode and focus on your work

If you want to focus on your work, it's convenient to disable desktop notifications. You can easily enable do not disturb mode and mute all notifications.

Enable do not Disturb to clear desktop notifications

These notifications will still be in the message bar so that you can read them later, but they will not pop up on the desktop.

15. Clean your system

This is something you don't need to do immediately after you install Ubuntu. But remember it will help you.

Over time, your system will have a large number of packages that are no longer needed. You can use this command to delete them all at once:

Sudo apt autoremove

There are other ways to clean up Ubuntu to free disk space, but this is the simplest and safest.

16. Adjust and customize the GNOME desktop according to your preferences

I highly recommend installing the GNOME setup tool. This will allow you to customize with additional settings.

For example, you can display battery capacity as a percentage, fix touchpad right-click problems, change Shell themes, change mouse pointer speed, display dates and weeks, change application window behavior, and so on.

There is no end to customization, and I may have used only a small part of its functionality. That's why I recommend reading these articles about customizing GNOME desktops.

You can also install new themes in Ubuntu, but personally, I like this version of the default theme. This is the first time I have used default icons and themes in a Ubuntu distribution.
