Finally. All the pieces are coming together for Wayland to truly be the actual future for Linux, even Linux Mint are now moving forward with it in their Cinnamon desktop.
News comes from their October 2023 overview post, which amongst other things, gave a mention of their new Wayland work. Mint's Clem notes work has "started on Wayland" and that it is "one of the major challenges our project had to tackle in the mid to long term". They have Cinnamon running on Wayland now too as shown in their screenshot:
Something to keep in mind though is with the Linux Mint 21.3 release coming it won't be the default session, and they don't expect it to be the default any time soon but they want it to finally be ready and so it will be included as an experimental option that you'll be able to pick from the login screen.
They've set up a Trello board you can follow on the progress and they don't think Wayland will be fully ready before 2026 so they're giving themselves two years to identify and fix up all the issues as they continue working on it.
Linux Mint 21.3 is due to release around Christmas time / late December 2023.
