I recently upgraded to Ubuntu 25.10, and decided to give Wayland another go since X.org isn't installed by default anymore.

Good news: My laptop (Lenovo P53) can now suspend / resume successfully. With Ubuntu 25.04 / Wayland it wouldn't resume successfully, which was a deal breaker.

Annoying thing: I had a script that I used to organize workspaces using wmctrl, which doesn't work anymore so I had to write a gnome-shell extension. Which (as somebody who's never written a gnome-shell extension before) was quite annoying as I had to keep logging out and in to test it. I got it working eventually but am still grumpy about it.

Overall: From my point of view as a user, the switch to Wayland has wasted a lot of my time and I see no visible benefits. But, it seems to basically work now and it seems like it's probably the way things are headed.

Edit: Actually I've seen some gnome crashes that I think happen when I have mpv running, but I can't say for sure if that's down to Wayland.
