First Steps

Now that Ubuntu is installed, there are a few essential tasks to complete before diving into daily use. Start by connecting to the internet. Wi-Fi can be configured through the system menu in the top-right corner, while wired connections typically work automatically. Once online, Ubuntu may notify you about available updates. It’s good practice to install these immediately because they often include important security patches and performance improvements. Open the Software Updater from your applications menu, or run $sudo apt update && sudo apt upgrade in the terminal if you prefer command-line tools.


Installing Essential Software

Ubuntu comes with a selection of preinstalled apps, but you’ll likely want to add a few more. The Ubuntu Software Center provides a user-friendly way to browse and install applications while the terminal offers faster access to a wider range of tools. For example, installing media codecs for video playback, productivity software like LibreOffice, or developer tools like Git can be done with simple commands. If you’re unsure where to start, consider adding a web browser like Firefox or a media player like VLC.


Configuring System Settings

Take a moment to explore the Settings application where you can personalize your desktop environment. Adjust display resolution, configure power settings to extend battery life on laptops, and set up peripherals like printers or external monitors. Ubuntu’s default appearance is clean and functional, but you can customize it further with themes, extensions, and dock preferences through the GNOME Teaks tool via the Software Center. If you’re using a laptop, enable Touchpad Tap-to-Click or adjust scroll direction to match your preferences.


Security and Maintenance

Security is a key advantage of Ubuntu, but a few extra steps will help keep your system protected. Enable the built-in firewall by running $sudo ufw enable in the terminal. This blocks unnecessary network traffic while allowing normal internet use. For added safety, set up automatic backups to save your files to an external drive or cloud storage. If your hardware requires proprietary drivers, which is common for graphics cards or Wi-Fi adapters, open Software & Updates and navigate to the Additional Drivers tab to install the recommended options.


Exploring Further

With the basics configured, you’re ready to explore Ubuntu’s potential. The command line located within the Terminal is a powerful tool for advanced tasks, but don’t feel pressured to learn it all at once. Over time, you’ll discover community resources like Ask Ubuntu or the official documentation for troubleshooting and customization tips. Remember, part of the fun with Ubuntu is experimenting—whether that’s trying new apps, tweaking your workflow, or learning how the system works on a deeper level.

By completing these post-installation steps, you’ve transformed a fresh Ubuntu install into a personalized, secure, and fully functional system. In future lessons, we’ll dive deeper into specific applications and advanced configurations, but for now, enjoy your new Linux environment!
