Ubuntu è la distribuzione Linux basata su Debian sviluppata da Canonical disponibile gratuitamente (tramite il supporto della comunità) oppure professionalmente a pagamento. Il desktop manager utilizzato è Unity, sviluppato dalla stessa Canonical, ma sono disponibili anche gli altri desktop manager (Gnome, KDE, XFCE…)

Ubuntu-MATE è uno spinoff diventato ufficiale e realizzato col desktop MATE.

Versione 22.04

Questa versione contiene (in Inglese):

MATE Desktop 1.26.1 🧉

Ubuntu MATE 22.04 features MATE Desktop 1.26.1. MATE Desktop 1.26.0 was introduced in 21.10 and benefits from significant effort 😅 in fixing bugs 🐛 in MATE Desktop, optimising performance ⚡ and plugging memory leaks. MATE Desktop 1.26.1 addresses the bugs we discovered following the initial 1.26.0 release. Our community also fixed some bugs in Plank and Brisk Menu 👍 and also fixed the screen reader during installs for visually impaired users 🥰 In all over 500 bugs have been addressed in this release 🩹

Yaru 🎨

Ubuntu MATE 21.04 was the first release to ship with a MATE variant of the Yaru theme. A year later and we’ve been working hard with members of the Yaru and Ubuntu Desktop teams to bring full MATE compatibility to upstream Yaru, including all the accent colour varieties. All reported bugs 🐞 in the Yaru implementation for MATE have also been fixed 🛠

Ubuntu MATE 22.04 LTS ships with all the Yaru themes, including our own “chelsea cucumber” version 🥒 The legacy Ambiant/Radiant themes are no longer installed by default and neither are the stock MATE Desktop themes. We’ve added an automatic settings migration to transition users who upgrade to an appropriate Yaru MATE theme.

Cherries on top 🍒

In collaboration with Paul Kepinski 🇫🇷 (Yaru team) and Marco Trevisan 🇮🇹 (Ubuntu Desktop team) we’ve added dark/light panels and panel icons to Yaru for MATE Desktop and Unity. I’ve added a collection of new dark/light panel icons to Yaru for popular apps with indicators such as Steam, Dropbox, uLauncher, RedShift, Transmission, Variety, etc.

I’ve added patches 🩹 to the Appearance Control Center that applies theme changes to Plank (the dock), Pluma (text editor) and correctly toggles the colour scheme preference for GNOME 42 apps. When you choose a dark theme, everything will go dark in unison 🥷 and vice versa.

So, Ubuntu MATE 22.04 LTS is now using everything Yaru/Suru has to offer. 🎉

AI Generated wallpapers

My friend Simon Butcher 🇬🇧 is Head of Research Platforms at Queen Mary University of London managing the Apocrita HPC cluster service. He’s been creating AI 🤖 generated art using bleeding edge CLIP guided diffusion models 🖌 The results are pretty incredible and we’ve included the 3 top voted “Jammy Jellyfish” in our wallpaper selection as their vivid and vibrant styles compliment the Yaru accent colour theme options very nicely indeed 😎

Ubuntu MATE stuff 🧉

Ubuntu MATE has a few distinctive apps and integrations of it’s own, here’s a run down of what’s new and shiny ✨

MATE Tweak

Switching layouts with MATE Tweak is its most celebrated feature. We’ve improved the reliability of desktop layout switching and restoring custom layouts is now 100% accurate 💯

We’ve removed mate-netbook from the default installation of Ubuntu MATE and as a result the Netbook layout is no longer available. We did this because mate-maximus, a component of mate-netbook, is the cause of some compatibility issues with client side decorated (CSD) windows. There are still several panel layouts that offer efficient resolution use 📐 for those who need it.

MATE Tweak has refreshed its supported for 3rd party compositors. Support for Compton has been dropped, as it is no longer actively maintained and comprehensive support for picom has been added. picom has three compositor options: Xrender, GLX and Hybrid. All three are can be selected via MATE Tweak as the performance and compatibility of each varies depending on your hardware. Some people choose to use picom because they get better gaming performance or screen tearing is reduced. Some just like subtle animation effects picom adds 💖

MATE HUD

Recent versions of rofi, the tool used by MATE HUD to visualise menu searches, has a new theme system. MATE HUD has been updated to support this new theme engine and comes with two MATE specific themes (mate-hud and mate-hud-rounded) that automatically adapt to match the currently selected GTK theme.

Windows & Shadows

I’ve updated the Metacity/Marco (the MATE Window Manager) themes in Yaru to make sure they match GNOME/CSD/Handy windows for a consistent look and feel across all window types 🪟 and 3rd party compositors like picom. I even patched how Marco and picom render shadows so windows they look cohesive regardless of toolkit or compositor being used.

Ubuntu MATE Welcome & Boutique

The Software Boutqiue has been restocked with software for 22.04 and Firefox 🔥🦊 ESR (.deb) has been added to the Browser Ballot in Ubuntu MATE Welcome.

41% less fat 🍩

Ubuntu MATE, like it’s lead developer, was starting to get a bit large around the mid section 😊 During the development of 22.04, the image 📀 got to 4.1GB 😮

So, we put Ubuntu MATE on a strict diet 🥗 We’ve removed the proprietary NVIDIA drivers from the local apt pool on the install media and thanks to migrating fully to Yaru (which now features excellent de-duplication of icons) and also removing our legacy themes/icons. And now the Yaru-MATE themes/icons are completely in upstream Yaru, we were able to remove 3 snaps from the default install and the image is now a much more reasonable 2.7GB; 41% smaller. 🗜

This is important to us, because the majority of our users are in countries where Internet bandwidth is not always plentiful. Those of you with NVIDIA GPUs, don’t worry. If you tick the 3rd party software and drivers during the install the appropriate driver for your GPU will be downloaded and installed 👍
