Ubuntu 22.04 Jammy Jellyfish is a solid, user-friendly Linux distribution, but like any fresh install, it benefits from a few quick tweaks to optimize performance, usability, and security. This list covers essential post-install fixes and improvements for anyone who just installed Ubuntu 22.04, whether you’re a new Linux user or a seasoned pro wanting a smoother experience right away.
Enable Proprietary Drivers
Ubuntu 22.04 often defaults to open-source drivers, which work well for most hardware but may not offer the best performance, especially for NVIDIA graphics cards. Open the “Software & Updates” app, go to the “Additional Drivers” tab, and select the recommended proprietary driver for your GPU. This improves graphics performance, gaming, and hardware acceleration significantly.
Install Multimedia Codecs
By default, Ubuntu doesn’t include many proprietary multimedia codecs due to licensing restrictions. Installing the “ubuntu-restricted-extras” package ensures support for MP3, H.264, and other common audio/video formats. Run sudo apt install ubuntu-restricted-extras to enable media playback in apps like VLC and browsers without issues.
Set Up a Firewall with UFW
Ubuntu 22.04 includes UFW (Uncomplicated Firewall), but it’s disabled by default. Activating it adds a layer of security by blocking unwanted incoming traffic. Enable it with sudo ufw enable and check status via sudo ufw status. You can configure rules to allow SSH or other services you use.
Enable Night Light for Eye Comfort
The Night Light feature reduces blue light emission by adjusting screen color temperature during evening hours. This helps reduce eye strain and improve sleep quality. Find it in Settings under “Displays” and schedule it automatically or manually adjust intensity.
Install GNOME Extensions for Customization
Ubuntu 22.04’s default GNOME desktop can be enhanced with extensions to add features like a system tray, better window management, or weather info. Visit extensions.gnome.org and install the browser integration to easily add popular extensions such as Dash to Dock or Clipboard Indicator.
Configure Timeshift for System Backups
Timeshift is a reliable tool for creating system snapshots, allowing you to restore your Ubuntu installation if something breaks. Install it via sudo apt install timeshift, set up snapshot schedules, and choose backup locations. This is invaluable for safe system updates or risky software installations.
Adjust Privacy Settings
Ubuntu collects some usage data by default, but you can control this in Settings under “Privacy.” Disable features like usage history and location services if you prefer tighter privacy. This reduces data sent to Canonical and limits background tracking.
Install Essential Development Tools
If you plan to compile software or develop, install the build-essential package which includes GCC, make, and other compiler tools. Use sudo apt install build-essential to get started quickly. This is a must-have for developers and power users.
Enable Tap-to-Click on Touchpads
By default, tap-to-click may be disabled on some laptop touchpads, which can feel unintuitive. Enable it by going to Settings > Mouse & Touchpad and toggling “Tap to click.” This simple fix makes navigation smoother without needing a physical click.
Update and Upgrade All Packages
Even fresh installs may not have the latest patches or software versions. Run sudo apt update && sudo apt upgrade -y immediately after installing Ubuntu 22.04 to ensure your system is fully up to date, improving security and stability.
How to Choose
When deciding which quick fixes to apply first, consider your priorities: hardware compatibility, security, usability, or development needs. Proprietary drivers and multimedia codecs are essential for hardware and media functionality. Security fixes like enabling UFW and configuring backups with Timeshift protect your system long-term. Customization options like GNOME extensions and tap-to-click improve daily usability but aren’t critical. If you’re a developer, installing build tools early saves time. Start with fixes that unblock your hardware or workflow, then move to enhancements and security.

Final Thoughts
Ubuntu 22.04 Jammy Jellyfish offers a modern and stable Linux experience, but applying these targeted quick fixes can make your system more secure, efficient, and enjoyable. Prioritize driver support and codecs to get your hardware and media working seamlessly, then layer on security and usability tweaks. With these adjustments, your fresh Ubuntu install will feel polished and ready for daily use.
