Prerequisites for Installation

Before installing Kooha Screen Recorder on Linux Mint 22, ensure your system meets the necessary requirements and preparations:

System Requirements

• Linux Mint 22 (or another Debian-based distribution)
• Active internet connection
• At least 5MB of free disk space for the application (plus additional space for recordings)
• Administrator (sudo) privileges

Preparing Your System

First, update your system packages to ensure you have the latest dependencies and security patches:

sudo apt update
sudo apt upgrade

This step is crucial for preventing potential compatibility issues during installation. Additionally, verify your display server type (X11 or Wayland) as Kooha supports both, but certain features may vary between them.

Method 1: Installing Kooha via Flatpak (Recommended)

Flatpak is the recommended installation method for Kooha on Linux Mint 22, providing a sandboxed environment that ensures better security and compatibility across different Linux distributions.

Installing Flatpak

First, check if Flatpak is already installed on your Linux Mint 22 system. If not, install it using:

sudo apt install flatpak

Adding the Flathub Repository

Next, add the Flathub repository which hosts the Kooha application:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

This command adds the Flathub repository to your system’s list of available software sources.

Installing Kooha via Flatpak

Now, install Kooha using the following command:

flatpak install flathub io.github.seadve.Kooha

The system will download and install Kooha along with any required dependencies. This process typically takes a few minutes depending on your internet connection speed.

Verifying Installation

Once installation completes, launch Kooha from your application menu or using the terminal:

flatpak run io.github.seadve.Kooha

The application should start, confirming successful installation. Flatpak installations receive automatic updates when new versions become available through the Flathub repository.

Method 2: Installing Kooha via Snap

Snap packages offer another convenient way to install Kooha on Linux Mint 22, though Flatpak is generally preferred for this application.

Enabling Snap Support

Linux Mint doesn’t include Snap support by default. To enable it:

sudo apt install snapd
sudo systemctl enable --now snapd.socket

You may need to restart your system after this step to ensure Snap is properly integrated.

Installing Kooha via Snap

Once Snap is configured, install Kooha using:

sudo snap install kooha

The system will download and install the Snap package. The installation creates appropriate desktop integration, allowing you to launch Kooha from your application menu.

Considerations for Snap Installation

While functional, the Snap version may have slightly different behavior than the Flatpak version regarding:

• File system access (due to Snap’s stricter confinement)
• Integration with system themes
• Startup time (Snap packages sometimes launch more slowly)

Nevertheless, the core functionality remains identical between installation methods.

Method 3: Building Kooha from Source

For users who prefer the latest features or need specific customizations, building Kooha from source code is a viable option.

Installing Build Dependencies

First, install the necessary development tools and dependencies:

sudo apt install git meson ninja-build libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgtk-4-dev libadwaita-1-dev

These packages provide the foundation needed to compile Kooha from its source code.

Cloning the Repository

Next, clone the official Kooha repository:

git clone https://github.com/SeaDve/Kooha.git
cd Kooha

Building and Installing

Use Meson and Ninja to build and install the application:

meson setup builddir
cd builddir
ninja
sudo ninja install

This process compiles the application and installs it system-wide. Building from source provides several advantages:

• Access to the latest features and improvements
• Ability to modify the source code for custom requirements
• Optimization for your specific system architecture

Building from source is recommended for advanced users who are comfortable with command-line operations and troubleshooting potential build issues.

Configuring Kooha for Optimal Use
