Linux Requirements
A couple of packages are required for Nyrna to run on Linux, even if you are using the Flatpak version. The following packages are required:
wmctrl
xdotool
You can install these packages by running the command for your distribution in a terminal:
Fedora
sudo dnf install wmctrl xdotool
Debian/Ubuntu
sudo apt install wmctrl xdotool
Arch
sudo pacman -S wmctrl xdotool
OpenSUSE
sudo zypper install wmctrl xdotool
After installing these packages, restart Nyrna if it is already running.
