Independent Polo 1.0 Brings a libweston Wayland Compositor to MATE; Two mate-panel Tasklist Changes Its Notes Prefer Shipped in 1.29.1 on Nov. 13

Polo 1.0, released November 12, ports Marco's window management to Wayland on libweston; MATE's Wayfire session is labelled experimental, and mate-panel 1.29.1 on November 13 lists two changes Polo's notes prefer.

Overview

Kerem Söke has released Polo 1.0, a Wayland compositor for the MATE desktop, according to LWN.net. The GitHub release was published at 03:03 UTC on 2026-11-12, and its notes begin “First release.” The project’s README describes Polo as “a port of Marco’s behavior and window management policies to Wayland, built on libweston and written in Vala and C”. Linuxiac adds that Polo “is an independent project, not an officially adopted replacement for MATE’s existing Wayland solution.”

LWN, which restates the announcement, quotes Söke’s stated aim: “The idea is to keep MATE behaving as closely as possible to how it does on X11, rather than changing the desktop to fit a different compositor.” Phoronix reported the release the same day, in a post stamped 12 November 2026 at 05:56 AM EST (Phoronix’s own US Eastern time).

What the release includes

The release notes list, among other items:

  • Marco’s window management policies, settings, themes and keybindings, with X11 programs handled by Polo’s own XWayland window manager.
  • An Alt+Tab switcher, tiling by keys and by dragging, workspaces, and effects that include wobbly windows and a desktop cube.
  • polo --session, a session manager the notes call compatible with mate-session-manager 1.28’s D-Bus API.
  • A DRM backend with hotplug and saved screen layouts, plus screenshots and screen sharing through xdg-desktop-portal and layer-shell support for mate-panel.

Installation is from a source tarball built with Meson and Ninja, according to the same notes; the README lists dependency commands for Fedora 44, and for Debian 14 and Ubuntu 26.04 and 26.10, and the notes say to pick “MATE (Polo)” in LightDM afterwards. Polo installs its own patched libweston 16.0.1 privately under $libdir/polo, and the README gives the licence as GPL-3.0-or-later. Phoronix describes Söke as a “MATE user” and says Polo builds on Wayland’s Weston library.

How it differs from MATE’s Wayfire session

The mate-desktop organisation’s mate-wayland-session README calls its Wayfire-based setup “a simple and experimental MATE session using Wayfire”. Linuxiac likewise says MATE “already has experimental Wayland support through Wayfire”.

The two projects describe different designs in their own READMEs. The Wayfire session says it runs “mate-settings-daemon in native wayland”, which requires mate-settings-daemon 1.29.1 or later, and notes that “GNOME, not MATE, gsettings preferences apply for fonts and icon themes under Wayland”. Polo’s README says mate-settings-daemon “continues running on XWayland”, with plugins that cannot work on Wayland disabled in the Polo session only, and that applications “continue to use the same GSettings/dconf keys”. The README states the motivation in the first person: “Wayfire wasn’t designed for MATE or other DEs, yet we’ve been trying to make MATE fit into it through plugins, workarounds, and compromises.” The Herald did not run either session and does not compare how they behave.

Limits the project lists

Polo’s notes say “Fedora’s mate-panel and many other MATE packages are built for X11 only; they need a Wayland-enabled build.” They also say GTK 3.24 leaks a little memory per closed window on Wayland, and warn against starting the magnifier until 1.0.1, adding “the issue is fixed but not on this release yet”. The README says “Polo is still under active development”, and LWN reports that Söke is seeking testers, particularly with multi-monitor setups.

Two mate-panel changes

The notes say a MATE panel build covering mate-panel pull requests 1598 and 1599 is preferable. Using GitHub’s UTC timestamps, both were opened on 2026-11-09 (21:35 and 21:36) by KeremSoke, the account that owns the Polo repository, after which Polo 1.0.0 was published on 2026-11-12 at 03:03. The account lukefromdc then merged them on 2026-11-12 at 22:38 and 22:49. The first hides Wayland tasklist windows that carry the skip-tasklist state, and the second reports task-button geometry to the compositor.

mate-panel 1.29.1 was published at 07:25 UTC on 2026-11-13 and lists both pull requests, along with a third from the same account on the Wayland tasklist context menu. By the Herald’s own count, the release notes list 53 entries, 13 of which mention Wayland in their titles; two examples are “[Wayland] Add support for autohide” and “[Wayland] Add support for ext-workspace-v1 in pager”. The cited pages do not say whether Fedora or any other distribution has built a Wayland-enabled panel from this release.

What remains unclear

Beyond Linuxiac’s statement that Polo is not officially adopted, none of the cited pages reports a position by the MATE project. The release notes describe installation from a source tarball and list a Fedora spec file in the repository, without mentioning prebuilt distribution packages. The README also says tests and “Marco Oracle documentation are in progress”.
