Boatswain
Native Stream Deck control for GNOME and other desktops.
Works on WaylandGPL-3.0-or-later
Install
Any distro
flatpak install flathub com.feaneron.BoatswainElgato ships no Linux software, so a Stream Deck is a USB HID device with no vendor support. Boatswain talks to it directly.
Setup requires a udev rule so your user can access the device without root; the Flatpak prompts for this, but on some distros you will need to add it manually before the deck is detected.
