We are now developing Discover Overlay. We strongly advise you try that instead!
pip will deal with dependencies, but for posterity the script needs
qt5-webengine pyqt5 python-pyqtwebengine python-pyxdg
git clone https://github.com/trigg/DiscordOverlayLinux.git cd DiscordOverlayLinux python -m pip install PyQtWebEngine python -m pip install .
On first use a window will show with two buttons "Layout" and "Position"
The first allows you to choose which widget you want to use as your overlay, and make any changes to the style.
The second shows you which display and where on it the overlay will be placed.
Extra Overlays can be added at will
