Changes in Ubuntu MATE 15.04 (Vivid Vervet)

Note: the changes below are between Ubuntu MATE 15.04 and 14.10. Some of these changes were already present / were backported to Ubuntu MATE 14.04 LTS (which was released after 14.10).





One of the most interesting changes for regular desktop users in Ubuntu MATE 15.04 is MATE Tweak, which is installed by default and comes with a couple of new features which many MATE users will love.





Firstly, the app now allows switching between Compiz and Marco, just like in Linux Mint 17.1 MATE, without having to restart the session:

CompizConfig Settings Manager, the tool which allows enabling various Compiz plugins and tweaking its settings, is not installed by default though.





And secondly, the tool can now be used to switch between various panel layouts, including: Ubuntu MATE (default), Eleven (with a top panel for the menu, systray, etc. and Plank at the bottom, as the app switcher/launcher) and more:

Depending on the packages installed on your system, more layouts can show up here. For instance, if you install the Ubuntu Indicator Applet from the PPA linked below, you'll get an extra panel layout with Ubuntu Indicators.





Another change compared to the previous (unofficial) Ubuntu MATE releases is that Ubuntu MATE 15.04 doesn't support Ubuntu/Unity Indicators out of the box because they don't support GTK2:

The Ubuntu Indicator Applet version used in previous Ubuntu MATE releases was patched to work with GTK2 and it was available in a PPA - since Ubuntu MATE 15.04 is an official Ubuntu flavor, it can't use PPAs by default and thus, the patched Indicator Applet is not provided on a fresh installation.





you can install the Ubuntu Indicator applet along with the Sound Indicator package (patched for MATE) from a PPA by following However,by following THESE instructions.





As for the artwork, Ubuntu MATE 15.04 ships with a new default theme, called Yuyo Dark, as well as a light "Yuyo" alternative:

However, Ambiant MATE is still used for the LightDM Greeter (login screen), probably because Yuyo still needs some tweaks to work to properly support it.





Also, compared to Ubuntu MATE 14.10, the default icon theme (Ambiant MATE) now uses green icons (this was already available in Ubuntu MATE 14.04), as you can see in the screenshots above.
