What To Do After Installing Linux Mint – Post Installation Linux Mint Setup

by

After installing Linux Mint, updating your system with `sudo apt update && sudo apt upgrade` ensures you have the latest security patches. But what to do after installing Linux Mint goes beyond just updates—you need to set up drivers, software, and backups to make your system fully functional. This guide walks you through every essential step, from tweaking settings to installing must-have apps, so you can start using Linux Mint with confidence.

Linux Mint is a beginner-friendly distribution, but a fresh install leaves you with a bare-bones system. Dont worry—you can customize it to fit your workflow in under an hour. Follow these steps in order, and you’ll have a stable, secure, and personalized desktop ready for daily use.

Update Your System Completely

First things first: run system updates. Open the terminal with Ctrl+Alt+T and type:

sudo apt update && sudo apt upgrade -y

This command refreshes the package list and installs all available upgrades. It may take a few minutes depending on your internet speed. After that, reboot if the kernel was updated.

You should also enable automatic updates. Go to Menu > Administration > Update Manager > Edit > Preferences. Set updates to install automatically weekly. This keeps your system secure without manual effort.

Check For Additional Drivers

Hardware like graphics cards, Wi-Fi adapters, or printers may need proprietary drivers. Open Driver Manager from the Menu. It scans your hardware and lists available drivers. Select the recommended one and apply changes.

For Nvidia GPUs, choose the latest stable driver. For AMD or Intel, the open-source drivers usually work fine. Reboot after installation to activate them.

Install Multimedia Codecs

Linux Mint does not include proprietary codecs by default due to licensing. You need them to play MP3, MP4, or DVD files. Open the terminal and run:

sudo apt install mint-meta-codecs

Alternatively, during installation, you could have checked the box “Install multimedia codecs.” If you missed it, this command fixes that. After installation, restart your media player.

Enable Flatpak And Snap Support

Flatpak and Snap let you install sandboxed apps from centralized stores. Linux Mint includes Flatpak out of the box, but you may need to add Flathub. Open Software Manager, click the three-dot menu, and enable Flathub.

For Snap, install it manually:

sudo apt install snapd

Then reboot or log out and back in. Snap apps like Spotify or Slack work well this way. However, some users prefer Flatpak for better integration with Mint.

Set Up System Backup

Backups save you from data loss. Linux Mint includes Timeshift for system snapshots. Open Timeshift from the Menu, choose RSYNC mode, and select a destination drive. Schedule daily or weekly snapshots.

For personal files, use the built-in Backup Tool. Set it to backup your home folder to an external drive or cloud service like Google Drive via rclone.

Create A Restore Point

After updating and installing drivers, take a manual snapshot with Timeshift. Click “Create” and label it “Post-Install Baseline.” This lets you roll back if something breaks later.

Install Essential Software

Your new system needs everyday apps. Here’s a list of must-haves for most users:

  • Web Browser: Firefox is pre-installed, but you can add Google Chrome or Brave from their official sites.
  • Office Suite: LibreOffice comes with Mint. For Microsoft Office compatibility, install OnlyOffice or WPS Office.
  • Media Player: VLC handles almost any format. Install it via Software Manager.
  • File Archiver: PeaZip or the default Archive Manager works for ZIP and RAR files.
  • Password Manager: Bitwarden or KeePassXC for secure logins.

Development Tools

If you code, install these:

  • VS Code or Sublime Text for editing.
  • Git for version control: sudo apt install git
  • Node.js and npm: sudo apt install nodejs npm
  • Python and pip: Usually pre-installed. Check with python3 --version.

Configure System Settings

Now tweak the desktop to your liking. Open System Settings from the Menu.

Appearance

Change the theme, icons, and fonts. Mint offers several built-in themes like Mint-Y or Mint-X. For a modern look, install the “Mint-Y-Dark” theme from the Themes section.

Adjust the panel (taskbar) position. Right-click the panel, select “Panel Settings,” and choose bottom, top, or left alignment. You can also add applets like a system monitor or weather widget.

Power Management

Go to Power Management. Set the display to turn off after 15 minutes of inactivity. For laptops, enable battery saving mode. Disable screen locking if you prefer.

Firewall And Security

Enable the firewall:

sudo ufw enable

Check its status with sudo ufw status. It blocks incoming connections by default, which is sufficient for most users.

Set Up Printing And Scanning

Linux Mint supports most printers via CUPS. Connect your printer via USB or network. Go to Menu > Administration > Printers. It should auto-detect. If not, install the printer driver from the manufacturer’s website.

For scanners, use Simple Scan. Open it from the Menu. It works with most USB scanners out of the box.

Connect To Network Shares

Access Windows shared folders by installing Samba:

sudo apt install samba

Then open Files > Other Locations > Connect to Server. Enter the address like smb://192.168.1.100/shared.

Optimize Performance

Linux Mint runs well on modest hardware, but you can tweak it further.

Disable Startup Programs

Open Startup Applications from the Menu. Uncheck apps you don’t need at boot, like Bluetooth or printing services. This speeds up login.

Adjust Swappiness

Swappiness controls how often the system uses swap space. Lower it for better responsiveness:

echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf

Reboot to apply.

Clean Up Junk

Use BleachBit to clear cache and temporary files. Install it from Software Manager. Run it monthly to free up disk space.

Customize The Desktop Environment

Linux Mint comes with Cinnamon, MATE, or Xfce editions. Cinnamon is the most popular. Here’s how to make it yours.

Add Desktop Icons

Right-click the desktop and select “Desktop Settings.” Enable icons for Home, Trash, and mounted drives. You can also add custom launchers.

Install Extensions

Cinnamon extensions add functionality. Open the Extensions app from the Menu. Browse and install ones like “Workspace Indicator” or “Transparent Panels.”

Change Keyboard Shortcuts

Go to System Settings > Keyboard > Shortcuts. Customize keys for launching terminal, switching workspaces, or taking screenshots. For example, set Ctrl+Alt+T for terminal.

Manage Software Repositories

Repositories are sources for installing software. Linux Mint uses Ubuntu repositories by default. You can add PPAs for newer versions of apps.

Add A PPA

For example, to get the latest LibreOffice:

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt update
sudo apt install libreoffice

Be cautious—PPAs can break your system if misused. Only add trusted ones.

Enable The Universe Repository

Some packages are in the “Universe” repo. Enable it if not already:

sudo add-apt-repository universe
sudo apt update

Set Up Cloud Storage

Sync files with cloud services. For Google Drive, use the “google-drive-ocamlfuse” tool. For Dropbox, install the official client from the website.

Alternatively, use Nextcloud for self-hosted storage. Install the client from Software Manager.

Sync With Rclone

Rclone supports many cloud providers. Install it:

sudo apt install rclone

Configure it with rclone config. Then mount your cloud drive to a local folder.

Install Gaming Tools

Linux Mint can run many games via Steam or Lutris.

Install Steam

Download the .deb package from the Steam website. Install it with:

sudo dpkg -i steam_latest.deb
sudo apt install -f

Enable Proton in Steam settings to play Windows games.

Install Lutris

Lutris manages game launchers. Add its PPA:

sudo add-apt-repository ppa:lutris-team/lutris
sudo apt update
sudo apt install lutris

Then install games from Epic Games Store or GOG.

Secure Your System Further

Beyond the firewall, take these steps.

Enable Full Disk Encryption

If you didn’t encrypt during installation, consider re-installing with LUKS encryption. It protects data if your laptop is stolen.

Use A VPN

Install OpenVPN or WireGuard. Many VPN providers offer Linux clients. Or use the built-in Network Manager to import .ovpn files.

Harden SSH

If you enable SSH, edit /etc/ssh/sshd_config to disable root login and change the default port.

Learn The Terminal Basics

Knowing a few commands makes troubleshooting easier.

  • ls – list files
  • cd – change directory
  • cp – copy files
  • mv – move or rename
  • rm – remove files (use carefully)
  • sudo – run as administrator

Practice with man to read manual pages.
