How to choose, use and configure a VPN in SuperGamer (My opinion)

Why These VPNs Shine on SuperGamer

SuperGamer is a gaming-centric distro built on Debian Stable, tailored for low-latency performance out of the box. It uses the apt family (apt-get, aptitude) as its package manager, and comes preconfigured with desktop environments such as Xfce and KDE Plasma. Gamers and power users alike appreciate its custom low-latency kernel, proprietary driver support and seamless Steam/Lutris integration. Because SuperGamer prioritises performance, any VPN you choose must:

Offer WireGuard or OpenVPN for minimal overhead
Provide a reliable kill-switch (critical during p2p transfers)
Integrate cleanly with NetworkManager or offer a native CLI/Gtk/QT client
Have lightweight dependencies to avoid bloating the live environment

Based on these criteria, the three standout choices are:

NordVPN – rock-solid WireGuard implementation (NordLynx), robust kill-switch and full CLI support.
ProtonVPN – offers both a GTK-based GUI plus CLI, strong privacy ethos and reliable Linux repo.
Mullvad VPN – peer-to-peer friendly, simple account-number model and excellent WireGuard support.

Installing and Configuring the Top Picks

NordVPN

NordVPN’s Debian repo integrates smoothly with SuperGamer’s apt stack. You’ll get NordLynx (their WireGuard variant) out of the box.

# Add NordVPN repo and key
sudo apt-get update
sudo apt-get install -y curl gnupg
curl -s https://repo.nordvpn.com/gpg/nordvpn_public.asc  sudo apt-key add -
echo deb https://repo.nordvpn.com/deb/nordvpn/debian stable main  sudo tee /etc/apt/sources.list.d/nordvpn.list

# Update and install
sudo apt-get update
sudo apt-get install -y nordvpn

# Login, enable kill-switch, connect
nordvpn login
nordvpn set killswitch on
nordvpn connect

Once connected, you can tweak the protocol:

nordvpn set technology NordLynx   # ensure WireGuard is used

ProtonVPN

ProtonVPN provides both a GTK GUI and a CLI tool via its official Debian repository. This is handy if you want a tray icon on Plasma or Xfce.

# Install prerequisites
sudo apt-get update
sudo apt-get install -y wget apt-transport-https

# Add ProtonVPN repo
wget -q -O - https://repo.protonvpn.com/debian/public_key.asc  sudo apt-key add -
echo deb https://repo.protonvpn.com/debian stable main  sudo tee /etc/apt/sources.list.d/protonvpn.list

# Update and install
sudo apt-get update
sudo apt-get install -y protonvpn protonvpn-cli

# Initialize and connect
sudo protonvpn init          # follow prompts (login, default profile)
protonvpn c --fastest        # auto-connect to fastest server

To enable the kill-switch:

sudo protonvpn configure    # enable NetShield and kill-switch options

Mullvad VPN

Mullvad uses an account-number system. Their official .deb and APT repo are straightforward on SuperGamer.

# Add Mullvad repo
echo deb https://repo.mullvad.net/deb/ apt main  sudo tee /etc/apt/sources.list.d/mullvad.list
wget -qO - https://repo.mullvad.net/gpg  sudo apt-key add -

# Update and install
sudo apt-get update
sudo apt-get install -y mullvad-vpn

# Start Mullvad and login
mullvad account status  # copy your account number if not set
mullvad connect         # connects with WireGuard by default

If you prefer a GUI, install:

sudo apt-get install -y mullvad-vpn-qt network-manager-mullvad

Then launch the QT client from your application menu or manage via NetworkManager to tie into SuperGamer’s desktop tray.
