Ubuntu MATE 15.04 Vivid Vervet Beta 1 Released, Gets Official Ubuntu Flavor Status

From webupd8.org. Author: Andrew | Date: Thursday, February 26, 2015

Ubuntu MATE 15.04 Vivid Vervet Beta 1 was released today. Let's take a look at what's new since alpha 2.

Unfortunately I didn't have time to test the other flavors (and for most of them, there's not much to say anyway), so I'll only cover Ubuntu MATE for this first beta release. However, I'll add links to the other flavors' release notes (download links included), below:

Ubuntu GNOME
Kubuntu
Xubuntu
Lubuntu (download link only; the official release notes are not available yet)
Ubuntu Kylin

I should also mention that as usual, Ubuntu (w/ Unity) doesn't take part in alpha and first beta releases.

Now back to Ubuntu MATE 15.04 Vivid Vervet beta 1. The most important news is that Ubuntu MATE is now an official member of the Ubuntu family.

The first Ubuntu MATE release was 14.10, followed by 14.04 (that's not a typo, the 14.04 release was after 14.10 because the Ubuntu MATE devs wanted to provide a LTS, since non-LTS versions are only supported for 9 months), but both versions were unofficial and used PPAs to provide the latest MATE Desktop 1.8, which is no longer the case with Ubuntu MATE 15.04 Vivid Vervet beta 1.

Since Ubuntu MATE is now an official Ubuntu flavor, all the packages it ships with are now available in the Ubuntu repositories - that include MATE Menu, MATE Tweak, its default GTK theme(s) and so on.

Speaking of MATE Tweak, the tool has received a pretty important new feature, which allows switching between different 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:

This also means that Plank, the default elementary OS application launcher, is now installed by default in Ubuntu MATE (but it's not used by default).

+Martin Wimpress posted a video which demonstrates this new MATE Tweak feature so check it out HERE. Note that in the video there are more panel layouts than there are available in Ubuntu MATE 15.04 Vivid Vervet beta 1 by default, because it depends on the packages installed on the system and for instance, the Ubuntu Indicator Applet, which was available in previous Ubuntu MATE releases, is no longer available in Ubuntu MATE 15.04 Vivid Vervet beta 1.

The reason for this is that the default Indicator Applet / Ubuntu Indicators don't support GTK2 by default. For the previous Ubuntu MATE releases, the Indicator Applet was patched to support MATE and it was available in a PPA, but since Ubuntu MATE 15.04 is now an official Ubuntu flavor, it can't ship with PPAs enabled by default and thus, it can't use Ubuntu Indicators out of the box.

However, you can install the Ubuntu Indicator Applet along with the Sound Indicator package (patched for MATE) in Ubuntu MATE 15.04 by following THESE instructions.

Another change in the latest Ubuntu MATE 15.04 Vivid Vervet beta 1 is the addition of Folder Color by default:

Folder Color is a tool which allows changing individual folder colors (useful to organize your folders, make some important folder stand out, etc.) and besides Caja, it supports Nautilus and Nemo.

Other changes include:

added menu categories to System > Preferences;
LightDM GTK Greeter Settings was updated to version 1.10;
updated the default GTK theme (Yuko) with better GTK 3.14 support;
thanks to a GTK2 bugfix, MATE should have better multi-monitor support;
MATE Tweak allows switching between Marco and Compiz without requiring a logout/login;
added PowerPC as an officially supported architecture;
updated LightDM GTK Greeter to 2.0.0 which now includes a MATE logo in the session switcher;
merged MATE Compatibility integration into upstream Compiz .

Here are a few more Ubuntu MATE 15.04 Vivid Vervet beta 1 screenshots:

This being a beta, there are a few known issues, most importantly: MATE 1.8x is not fully compatible with glibc>=2.43.1 and while this was fixed upstream, it's not available in 15.04 yet so for now, you'll have to use a PPA to get the fixes.

Other known issues include: the notification tray crashes on first start and randomly from time to time (32bit only), live switching between Compiz and Marco is experimental and may result in missing window decorations on some old GPUs (and in VirtualBox, at least that was the case in my test) and more.

Default applications/packages

Ubuntu MATE 15.04 Vivid Vervet beta 1 ships with the following applications installed by default: Caja 1.8.2, Pluma 1.8.1, Firefox 34, Thunderbird 31.4.0, LibreOffice 4.4.0, VLC 2.2.0, Rhythmbox 3.1, Shotwell 0.20.2, Pidgin 2.10.9, HexChat 2.10.1, Transmission 2.84, Cheese 3.14.1, two terminals - MATE Terminal 1.8.1 and Tilda 1.2.2 (which can be triggered via the F12 key), and Eye of Mate 1.8.0, on top of MATE Desktop 1.8.1.

Under the hood, the first Ubuntu MATE Vivid beta ships with the Ubuntu Linux Kernel 3.18.0-13, based on the upstream 3.18.5 Linux Kernel, Xorg server 1.16.2.901 and Mesa 10.5.0 RC1 (with RC2 available in the Proposed repository).

How to enable the Composting Manager in Ubuntu Mate

I've noticed that the Ubuntu Mate Tweak utility has been removed. For anyone looking to enable the Composting Manager. Here is how to do it from the Terminal. Enjoy....

first ensure you have installed compiz:

sudo apt-get install compiz compiz-plugins compizconfig-settings-manager

Open compiz settings manager by typing ccsm in the terminal, or just find it in the dash.
Under EFFECTS, enable Window Decorations.

This is where I got stuck for 2 months. In most distros, this is all you have to do, but there is another step in Mate:

Open a terminal and type:


dconf write /org/mate/marco/general/compositing-manager true

You should now have compositing enabled.

Why Evolve OS could win you over to Linux and me away from Ubuntu

Jack Wallen has found the one take on Linux that could possibly move him away from his distribution of choice since 2006.

There are so many Linux distributions, each one claiming that they are the one flavor best designed for the new user in mind. Ubuntu, Linux Mint, PCLinuxOS -- all outstanding distributions and very much ready for users who want a platform built on the premise that Linux isn't nearly as challenging as many people assume.

In 2014, a new distribution appeared out of nowhere, one that cut straight to the heart of the matter and promised to deliver a Linux distribution like no other. That distribution is Evolve OS. For the longest time, the distribution was in a state of limbo, and the best you could do was download an alpha and hoped it would run. I tried a number of times and finally opted to just install the Budgie desktop on a Ubuntu distribution. That attempt gave me an idea of how Evolve OS would look, but not much more.

All of that changed last week when the beta of Evolve OS was finally released, and the distribution could finally be tested against what's considered the gold standard of user-friendly Linux distributions.
It not only fared well, it crushed the competition.
I should probably preface this by saying that I'm already a bit biased towards the Budgie interface. It's a near clone of the Chrome OS UI -- beautiful, elegant, and simple (Figure A). It makes lesser hardware sing, and it's quite stable for a beta.
Figure A

The Budgie desktop in action.

Evolve OS is built from scratch, using a fork of the PiSi package manager, and it's integrated with the GNOME stack to avoid technical debt and needless overhead.
What's underneath the hood will not concern the new user -- but what will is the complete lack of a learning curve. Any user could hop onto Evolve OS and feel right at home. At the heart of that is the similarity to the Chrome OS UI. Although the Chromebook, by nature of its design, does have limitations (I should also mention that I'm a big fan of the Chromebook), the UI is as flawless an interface as you'll ever find. Evolve OS takes perfect advantage of this and re-creates that platform, sans limitations.

Imagine the Chromebook with the ability to run full-blown applications and work seamlessly offline. That's the very heart and soul of Evolve OS. With a simple menu, notification area, and panel, Evolve OS enjoys a familiar desktop metaphor that has worked for decades with the modern, minimal twist of Chrome OS.
From the user's perspective, Evolve OS borrows the following from the GNOME stack:

Files -- GNOME file manager
Maps -- GNOME map tool
Weather -- GNOME weather app

It must be said that Budgie is not a fork of GNOME 3. Budgie was built from scratch and uses its own window manager and panel. Outside of the listed apps above, most of the borrowed GNOME stack is underneath the hood.

Why Evolve?

The answer to this question is quite simple. If you're a fan of Chromebooks but long to be able to add an addition layer of usability and power on top, Evolve OS is for you. If you're looking for the epitome of elegance on a desktop, Evolve OS is for you. If you're looking for the single lowest barrier to entry for Linux, Evolve OS is for you.

Why not Evolve?

It's very important to remember that Evolve OS is in beta. This means that you'll find tiny corners that are a bit rough. Take, for instance, the Software Center (Figure B).
Figure B

The Evolve Software Center.

The Software Center is quite limited at the moment. With a minimal amount of available packages to install, you'll find yourself having to go the old-school route and install manually. Evolve OS uses the eopkg, which is a fork of the PiSi package manager. You can install a package with a command similar to:
sudo eopkg install audacity
Personally, I'll be following Evolve OS closely to see when the distribution comes out of beta. When it does, it's quite possible that I could evolve from Ubuntu to this incredibly easy-to-use take on the Linux environment. That's a fairly impressive task for any new distribution -- to take me away from my Linux distribution of choice since 2006.
What do you think? Is Evolve OS just what the Linux platform needs to win over new users? Why or why not?
