What changed since the Ubuntu MATE 16.04 LTS release?

Ubuntu MATE 18.04 LTS Final Release

Just about everything! Ubuntu MATE 18.04 is ramm8ed to the rafters with new features and improvements compared to 16.04.

MATE Desktop 1.20.1

The MATE Desktop has transitioned from the GTK 2.24 based MATE 1.12 to the very latest MATE 1.20.1 based on GTK 3.22. This migration has been several years in the making, and most of 2016 and 2017 was spent refining the GTK3 implementation. The move to GTK3 has made it possible to introduce many of the new features you’ll read about below.

Support for libinput has been added and is now the default input handler for mouse and touchpad, which has resulted in much improved responsiveness and support for multi-finger touch gestures.

Thanks to our friends at Hypra.fr accessibility support (particularly for visually impaired users) has seen continued development and improvement. MATE Desktop is proud to provide visually impaired users the most accessible open source desktop environment.


High DPI displays have a high resolution relative to their physical size that results in an increased pixel density compared to standard DPI displays. They are mostly found in high-end laptops and monitors. Our friends at elementary OS wrote a great blog post explaining What is HIDPI and why does it matter.

MATE Desktop 1.20 supports HiDPI displays and if you have one then Ubuntu MATE will automatically enable pixel scaling, presenting you with a super crisp desktop and applications. HiDPI hints for Qt applications are also pushed to the environment to improve cross toolkit integration. Every aspect of the Ubuntu MATE, its themes, its applications, its icons, its toolkit assets have been updated to take advantage of HiDPI.

Should you have a HiDPI display and want to disable HiDPI scaling you can do so via MATE Tweak (for the desktop) and Login Window (for the greeter), both are available in the Control Centre.


The File Manager (Caja)

We’ve added some new features to the file manager (Caja).

  • Added Advanced bulk rename – A batch renaming extension.
  • Added Encryption – An extension which allows encryption and decryption of files using GnuPG.
  • Added Hash checking – An extension for computing and validating message digests or checksums.
  • Added Advanced ACL properties – An extension to edit access control lists (ACLs) and extended attributes (xattr).
  • Updated Folder Color – An extension for applying custom colours and emblems to folders and files.
  • Replaced the deprecated caja-gksu with caja-admin which uses PolicyKit to elevate permissions in the file manager for administrative tasks.

gksu is deprecated and being removed from Debian. We are aligning with that objective by replacing all use of gksu with PolicyKit.
