I had the same display failure, but 4 times in about 9 months. It made me pretty done with the whole thing. I only got the laptop back from the repair centre 2 or so weeks ago but I have no faith the issue is properly fixed now. Let’s see how it turns out, if it happens again I’m going to throw this thing out of the window.
Ok but you’re talking about Cinnamon. Cinnamon’s Wayland support is experimental sure, but that doesn’t mean Wayland itself is. I mentioned KDE Plasma and GNOME because they are the ones using Wayland for the longest now and have the best support for it and there it works better than X11.
