As we settle well into the new month, the Linux Mint team has released a new update on the state of the project detailing work done last month.
Back in March, the dev team revealed a new Wayland-compatible screensaver that directly replaces the old, janky cinnamon-screensaver (which launched back in 2013 with Linux Mint 15 "Olivia"). Now the team has announced that Wayland itself is going to be "fully supported" in the next version of Cinnamon, which is scheduled to ship inside the next version of Linux Mint sometime around Christmas this year.
Cinnamon now properly handles window sizing and positioning for context menus and applet popups while preventing app focus stealing. Developers added hardware-accelerated GBM over EGL for Nvidia chips to handle desktop rendering smoothly alongside standard driver pipelines. The system handles multiple monitors, and KVM switches much better, while Chromium utilities like Slack render sharp fonts under the new HiDPI scaling.
Desktop panels in Cinnamon will even display file transfer progress from Nemo directly, and root applications running via pkexec execute as native clients rather than running through Xwayland translation layers.
The next version of Linux Mint will come with a new cinnamon-list-windows command that lists all open window instances alongside their precise sizes, coordinate locations, HiDPI parameters, and backend execution details.
Muffin now rounds coordinates and dimensions for Clutter actors to stop blurry interface components from ruining the visual experience. The environment now integrates with systemd graphical-session targets to maintain standard compatibility with various upstream Linux utilities.
Other fixes the team added include corrections for LightDM manager configurations and Slick Greeter fingerprint authentication, allowing users to log in directly by scanning their finger without having to hit the Enter button. The devs also patched CVE-2026-59159, a severe vulnerability in mintupdate that allowed local attackers to execute code as root because the mint-refresh-cache tool failed to properly validate parent window IDs passed to Synaptic.
