What to do after installing Ubuntu 19.10

Introduction

Installing Ubuntu 19.10 is just the beginning of your journey into the world of this versatile and powerful operating system. While the installation process is straightforward, knowing how to optimize your new system is key to fully leveraging its capabilities. This comprehensive guide will take you through the essential steps and modifications you should make after installing Ubuntu 19.10, ensuring a smoother and more productive user experience.

Update Your System

Why It’s Important

The first step post-installation is to update your system. Software developers continually release updates to fix bugs, improve performance, and enhance security. Therefore, it’s crucial to ensure that your newly installed Ubuntu version is up-to-date.

How to Update

To update your system, open a terminal window (you can do this by pressing Ctrl + Alt + T or searching for “Terminal” in your applications). Then, run the following commands:

bash
sudo apt update
sudo apt upgrade

The sudo apt update command refreshes the package lists to get information on the newest versions of packages and their dependencies. The sudo apt upgrade command then installs the latest versions of all installed packages.

Additional package management

For even greater control over your packages, consider using:

• Synaptic Package Manager: A GUI for managing software packages.
• Ubuntu Software Center: For non-command-line users, this software center provides a user-friendly interface to install applications.

Install Essential Software

Choosing Your Software

After updating, you may want to install essential software to enhance your productivity. Here’s a list of popular applications worth considering:

1. Web Browsers: While Firefox comes pre-installed, you may also want to install Google Chrome or Chromium for your browsing needs.

   • To install Chrome, visit the Google Chrome website and download the .deb package.
   • For Chromium, you can use:
     bash
     sudo apt install chromium-browser

2. Media Players: Consider installing VLC Media Player for comprehensive media file support.
   bash
   sudo apt install vlc

3. Office Suite: LibreOffice is installed by default, but if you prefer an alternative, Microsoft Office can be run through Wine or you can consider alternatives like OnlyOffice.

4. development tools: If you’re a developer, install programming languages and IDEs suited to your needs. For Java, you might want to install IntelliJ or Eclipse, and for Python, PyCharm is excellent.

5. Graphics and Design Software: GIMP is a powerful alternative to Photoshop. Install it using:
   bash
   sudo apt install gimp

Using Snap and Flatpak

Ubuntu also supports Snap and Flatpak for software installation, which allows you to install applications in a contained environment. For Snap, you can use:

bash
sudo snap install

And for Flatpak, ensure it’s installed and then run:

bash
flatpak install

Customize Your desktop environment

Changing Themes and Icons

Customization can significantly enhance your user experience. Ubuntu 19.10 uses GNOME by default, and there are numerous themes and icon packs available to personalize your desktop.

1. Install Gnome Tweaks:
   bash
   sudo apt install gnome-tweaks

2. Use the tool to change themes and icons which are available from repositories like GNOME Look or via the GNOME Software Center.

Widgets and Extensions

Utilize GNOME extensions for additional functionality. Some popular extensions include:

• Dash to Panel: Combines the top bar and application dock.
• User Themes: Allows you to apply different themes more easily.

Visit extensions.gnome.org to browse and install various extensions.

Enable Firewall Protection

Why Use a Firewall?

Using a firewall adds a layer of protection against unauthorized access and potential threats. Ubuntu comes with ufw (Uncomplicated Firewall), a simplified interface to manage firewall rules.

Configuring UFW

To enable the firewall, open the terminal and type:

bash
sudo ufw enable

To check the status, you can run:

bash
sudo ufw status

Remember to allow specific applications or ports as needed:

bash
sudo ufw allow # e.g., sudo ufw allow ssh

Optimize system performance

System Monitoring

System monitoring tools can provide insights into your system’s performance. Install tools like htop for terminal-based monitoring or gnome-system-monitor for a graphical interface:

bash
sudo apt install htop

Swap File

In instances of low RAM, enabling or adjusting a swap file can optimize memory management. You can check your current swap status by running:

bash
swapon –show

Clean Up Unnecessary Files

Clearing out unwanted packages and cache can also free up space. Use the command:

bash
sudo apt autoremove

Backup Your System

Importance of Backup

Having a backup strategy is essential in protecting your data. Ubuntu provides several tools for backing up your system, such as Deja Dup, which comes pre-installed.

Configuring Deja Dup

1. Open Backups from your applications.
2. Follow the prompts to select folders you want to back up, the backup location (local or cloud), and set a schedule for periodic backups.

Conclusion

Taking the time to set up your Ubuntu 19.10 environment can lead to a more efficient and enjoyable experience. By following these steps, you’ll enhance security, optimize performance, and customize your desktop to better suit your workflow.

In the fast-evolving world of technology, staying informed about tools, updates, and practices will ensure that you can reap the full benefits of your Ubuntu installation. Enjoy exploring and using your new operating system!
