Linux Mint 27 Adrien Cinnamon – What can we expect from the new Christmas 2026 release

- by John Been

We are rapidly approaching the end of the year, and for Linux users, one of the significant annual events around Christmastime is the release of a new version of Linux Mint. This year is particularly notable, as the team behind Linux Mint has decided to shift to a schedule of just one release per year, accompanied by a new version-numbering convention. In this article, we take a look ahead at what we can soon expect from the new Linux Mint 27 “Adrien” Cinnamon release.

Introduction

Linux Mint is for me personally one of the most important Linux distributions for both newcomers to the Linux world and more experienced Linux users who require a robust out of the box experience, so they can be productive without configuration and tinkering. We are getting ever closer to the end of 2026, which means, among other things, that we can look forward to a new release of Linux Mint.

This year the Linux Mint team has decided to slow down its development and release frequency from a 6-month release schedule to a yearly schedule, and wants to invest the extra available time in more impactful and more reliable improvements. The result of slowing down and not feeling rushed is that the new Linux Mint 27 “Adrien” is becoming one of the most ambitious Cinnamon releases in years. The Linux Mint developers have spent most of 2026 improving core technologies, modernizing the Cinnamon desktop environment, and are preparing Linux Mint for a future where Wayland is fully supported.

Based on the monthly Linux Mint development updates from February through October 2026, which can be found on the Linux Mint blog, I extracted a complete overview of what you can expect in the upcoming Linux Mint 27 “Adrien” release.

Wayland

One of the biggest changes coming to Linux Mint 27 happens behind the scenes. After years of development, Wayland support in Cinnamon is no longer considered experimental and will be officially supported alongside X11.

According to the Mint developers, Wayland has now reached near feature parity with the traditional X11 session. A lot of work has gone into closing the remaining gaps, including improvements to window management, multi-monitor setups, HiDPI scaling, hardware acceleration, NVIDIA compatibility, and overall desktop stability. Other improvements include better focus handling, improved support for KVM switches, working progress indicators, and numerous fixes throughout Cinnamon and related components.

The good news for some longtime Linux Mint users is that this is not the end of X11 replacement, at least not yet. Linux Mint 27 will continue to offer both Wayland and X11 sessions, allowing users to choose whichever works best for their hardware, workflow, and applications. For most users, that means you can start benefiting from Wayland’s modern architecture without being forced to leave X11 behind if you still depend on it.

New screensaver

Cinnamon will get a completely redesigned screensaver that will be tightly integrated into the desktop environment, instead of being a separate application. In Linux Mint 27, Cinnamon will support both this new and the legacy screensavers, but in the longer term, the Linux Mint team will retire the older solution and simplify screen locking and power management. The team will focus more on privacy and security, instead on just the traditional screensaver functionality. The result to be expected for Linux Mint 27 will be a more native look, smoother animations, full Wayland compatibility and better privacy and security support.

XApp

One of the less visible but quite important parts of Linux Mint is the XApp project. This project was originally launched in 2016 to try to solve a growing problem of application fragmentation in the Linux desktop world.

Many applications are becoming increasingly tied to their specific ecosystems desktop environments. GNOME apps, for example, often start relying on GNOME-specific technologies and design patterns, which makes them feel less at home on other desktop environments. With XApps, the Linux Mint team tries to find an answer to this fragmentation issue. The idea behind XApps is to not maintain separate versions of essential applications for the Linux Mint Cinnamon, MATE, and Xfce editions, but to develop a shared set of core applications that work consistently across all editions. This means improvements made to one application benefit every Linux Mint user, regardless of which desktop environment is being used.

The XApp project is built around a few simple principles:

  • Use modern technologies and toolkits, including GTK and HiDPI support.
  • Preserve traditional desktop workflows with familiar menus, title bars, and interfaces.
  • Remain as desktop-agnostic and distribution-agnostic as possible.
  • Keep the functionality that users expect instead of removing features in the name of minimalism.
  • Maintain compatibility with a broad range of Linux distributions.

In Linux Mint 2027, all editions ship with the same XApp libraries and applications. This allows the development team to spend its time improving a single application ecosystem rather than maintaining multiple alternatives that essentially solve the same problems. So, the goal of XApps is not to reinvent existing software, but to focus on maintaining and improving proven applications that can be shared across multiple desktop environments.

For Linux Mint 27, XApps continues to play a key role in the overall desktop strategy. The project is still evolving, and new applications are being added. Clockenstein, for example, is a new dedicated XApp application for clocks, alarms, timers, and other time-related functionality.

The Linux Mint team has created a dedicated website to make it easier to discover all the XApp components: https://xapp-project.org

Clockenstein calendar application

Like mentioned in the previous section about XApp, an addition to the growing XApp ecosystem is Clockenstein, a new calendar application developed by the XApp Project. The goal is not to create complex productivity suite, but to provide a focused and desktop-friendly calendar application that fits naturally into Linux Mint and other Linux distributions. Clockenstein supports local calendars as well as popular online calendar services, making it suitable for both personal and cloud-synchronized workflows.

Some of its key features include:

  • Support for local calendars
  • Integration with Google Calendar
  • Compatibility with CalDAV services
  • Nextcloud calendar synchronization
  • Event reminders
  • Synchronization monitoring
  • Desktop notifications
  • Cinnamon panel integration

Clocks

Linux Mint 27 introduces the small but convenient alarms app, called Clocks. This is a simple application for setting up and managing your different alarms. The interface is simple and easy to use. It allows you to set one-time alarms, but also recurring alarms, choose custom sounds, and receive notifications even when the application itself is not open. Clocks is actually part of the before mentioned Clockenstein calendar app. All alarm notifications are handled by the Clockenstein daemon and notification agent.

Redesign of Thingy

Linux Mint’s XApp document library application, Thingy, has gotten a redesign. Before, documents were grouped by the application used to open them, which was not always the most intuitive approach. The new version organizes documents by file type instead, making the library easier to navigate regardless of which applications are installed on your system.

The sidebar of Thingy now includes customizable document categories, and you can also create your own groups. The update of Thingy also gives more control over your recent documents list, allowing you to remove individual entries or clear the entire history with a single click.

A new dedicated EPUB reader

Linux Mint 27 will also offer the new XApp EPUB reader Xepub. The Xepub app tries to provide a reading experience comparable to what you expect from devices such as a Kindle or Kobo. The Xepub application includes everything you need from a modern ebook reader, like navigation of chapters, search within books, add bookmarks, and continue reading exactly where you left off when reopening a book. Also a very nice feature is the ability to select words and directly look them up online. Xepub also supports annotations, which allows you to highlight passages, choose highlight colors, and add personal notes.

Nemo – improved response time

The Nemo file manager will receive significant performance improvements in Linux Mint 27. One of the most noticeable changes is navigation speed. Previous versions intentionally delayed folder rendering by around 200 milliseconds to ensure smooth visual transitions. That delay is now reduced or removed where possible. This gives a snappy and visible performance improvement depending on the situation, for example when opening certain folders.

Nemo – better interactive search

File manager Nemo’s interactive search (open a folder and start typing) has been redesigned and improved. Previously, typing inside a directory would display a small search box and jump between matching files. In Linux Mint 27, interactive search switches to a filtered view that instantly narrows visible results as you type. This provides more logical search behavior, easier navigation, better visibility of matching files and overall a much more modern file manager experience.

Nemo – preview pane

I am very happy with this new functionality in the Nemo file manager. Linux Mint 27 introduces a preview pane in Nemo that can be toggled with F7, or by clicking the dedicated button in the status bar. The preview pane supports images, audio files, video files and it also shows related metadata. With this functionality you can quickly look at content without opening an actual application, like a document editor, drawing application or photo editor. This makes basic file management much more efficient and fast.

New screenshot tool

The Linux Mint team is replacing its current screenshot solution with a dedicated for Cinnamon developed screenshot utility. The new tool will introduce some new features that are missing in the current application. You can now capture window screenshots with or without window shadows, choose if you want a screenshot of all your monitors or only one of them, if applicable. And you can crop screenshots before saving or copying them.

Under the hood the way there are improvements how screenshots are captured to better handle the differences between Client-Side Decorations (CSD) and Server-Side Decorations (SSD). This solves the issue in the current screenshot application, which sometimes could leave traces of window shadows around rounded corners. And the option to remove window frames is often unreliable. This will all be much better with the new screenshot tool. Within Linux Mint 27 you can accurately capture windows, with or without their shadows. When shadows are included, the tool recreates them correctly, and screenshots without shadow are cleaned from any unwanted semi-transparent pixels around window edges. 

The result will be a more capable screenshot tool that produces cleaner and more accurate screenshots and also gives users more control over how their screen captures look.

UI improvements

The Cinnamon desktop is getting support for what the Linux Mint team calls draggable Clutter dialogues. Traditional dialogues can block access to the rest of the desktop, but these new dialogues in Linux Mint 27 stay on top while still allowing you to interact with other applications. You can even move them out of the way if you need to check something before responding.

The Linux Mint team is also refining the look and feel of system dialogues and is solving some visual issues. For example, in the current Cinnamon version, buttons in some dialogues are placed very close to each other and also take the whole width of the dialog. This will be improved with much more logical placement and sizing. Also the often inconsistent title alignment and title bars that can look empty and unused, will see visual improvement.

Tree views and list views will also have an update, with rounded edges. This brings them in line with other redesigned and improved UI components. Also there will be a better consistency of the available desktop icons. The Mint-Y, Mint-L, and Mint-X themes will use what is called XSI (XApp Symbolic Icons). That means when an application like Xed opens a file chooser dialog, the visible icons will exactly match the icons that are used in the Nemo file manager.

All these changes are giving Linux Mint 27 a more unified, visually consistent, better to understand and more modern visual experience.

New sleep mode management

If you are a laptop user running Linux Mint, you will gain a powerful and highly desirable new feature that provides better battery management. This ensures you will not be surprised anymore if you leave your laptop in sleep mode for too long while it is not connected to a power source. Currently, closing the lid of a laptop brings the device into a suspend mode. This mode is convenient and fast, but the fact that it keeps using power from your internal battery is a big issue. At some moment the battery is empty and you lose your active session and potentially unsaved data.

The new Linux Mint 27 will have a dedicated Sleep Modes section in the System Administration tool that makes the new (well, it already existed, but Ubuntu removed it, but Linux Mint now brings it back) hibernation function easy to configure. Supported options are Suspend, Hibernate, Suspend-then-Hibernate and Hybrid Sleep.

So, Linux Mint 27 is bringing hibernation support. Unlike normal suspend functionality, hibernation saves your entire session to disk and completely powers off the system, allowing you to pick up exactly where you left off without emptying the laptop battery. Linux Mint 27 will have a dedicated configuration screen that helps configure and enable Hibernation simply and correctly.

This same screen also introduces support for hybrid sleep and suspend then hibernate. Hybrid sleep combines the speed of suspension with the safety of hibernation by saving your session to disk while also entering a suspended state. Suspend then hibernate goes one step further by initially suspending the system and automatically switching to hibernation when the battery reaches a critical level.

Network improvements

Networking will be improved in Linux Mint 27. It will support WPA3 WiFi Protected Access 3 security and OWE Opportunistic Wireless Encryption. Together, this will improve compatibility with modern wireless infrastructure and will strengthen security.

Better Fingerprint Reader Support

Fingerprint login will be improved by enabling authentication just by touching the finger print sensor, without the need to press Enter.

Superlight system monitor

Superlight is a new system monitoring application built directly into Linux Mint 27 that gives you a clear overview of what is happening on your system. Through a single interface with clearly organized sections, you can monitor CPU and RAM usage, swap space, GPU activity, network traffic, disk I/O, temperatures, fan speeds, power consumption, battery health, and storage usage.

Superlight includes both application and process monitoring, making it easy to see exactly what’s running and how many system resources each application or process is consuming. If you are a little bit more of a power user, you will appreciate the ability to customize, reorder, and sort columns to suit your wy of working, with all preferences automatically remembered between sessions.

Superlight also includes informative graphs on the Battery page, making it easy to view historical data such as battery charge levels and power input and output. In addition, the Storage page helps you quickly identify what’s consuming disk space. You can drill down into folders and files or view storage usage for platforms such as Steam and Flatpak to see exactly where your disk space is going.

In my opinion, Superlight is a welcome addition to Linux Mint 27. It brings system monitoring, process management, battery insights, and storage analysis together in a single, easy-to-use tool.

Unfold archive manager

Linux Mint is also introducing their own archive manager Unfold, which is a very lightweight archive application. It includes features like archive browsing, archive creation, extraction support, 7zip and RAR compatibility, and supports Password-protected archives.

Velocitty terminal application

Linux Mint 27 will also come with a new terminal application, Velocitty. It has a really nice design and offers some practical and usable features, and supports customizable color palettes. Velocitty has a tab overview for managing multiple terminal sessions. You can reorder tabs, move them between windows, or detach them into a separate window, much like you work with browser tabs in for example Firefox.

For users who regularly work on the same projects or servers, custom tabs are particularly handy. You can assign a name, color, and startup command to a tab, and even have specific tabs open automatically when Velocitty launches. A built-in bookmark menu then provides quick access to all your saved sessions.

The terminal can be configured to use your preferred shell and run startup commands automatically. It also includes useful features such as path shortening to keep prompts readable and color-coded tabs that help to make a distinction between root sessions, remote SSH connections, and active processes.

New Kernel Management System

Management of kernels will move from the Update Manager to the new System Administration tool and is completely redesigned. The new kernel manager works in both Linux Mint and LMDE and will focus on kernel series instead of individual kernel versions. You can choose which kernel series you want to follow and how many older kernels you like to keep. New kernel updates then arrive through the Update Manager and outdated kernels are automatically removed to save disk space and minimize clutter. But to prevent important kernels from being removed, you can mark them as protected, so they are excluded from automatic cleanups.

The tool also includes cleanup history, manual cleanup options, and support for custom kernel series such as OEM and real-time kernels. And advanced Linux Mint users are still able to view, install, remove, and manage individual kernels.

Final words

For me, the arrival of a new release of Linux Mint always feels a bit like how I felt as a small child unwrapping a birthday or Christmas present. It remains remarkable that we all have access to such a wonderful, community-built operating system. A system that, unlike macOS or Windows, can be installed and used on relatively older computers, where it still runs quickly and efficiently, and offers everything out of the box that a modern computer user needs. Switching to a system like Linux Mint allows us to keep using our devices for a much longer time, rather than having to send them off to a landfill. Linux distributions like Linux Mint demonstrate what people can achieve when they combine their passion, knowledge, and skills through effective collaboration.

Linux Mint 27 seems to concentrate on the fundamentals, like performance, reliability, hardware compatibility, productivity. If everything that is announced throughout 2026, like I have written down in this article, makes it into the final release, the new Linux Mint 27 “Adrien” is probably one of the most significant Linux Mint releases in years.
