an automated settings migration to transition customers who improve to an
applicable Yaru MATE theme.

Cherries on high 🍒

the reliability of desktop structure switching and restoring customized layouts is now 100%
correct 💯

Having your desktop your approach in Ubuntu MATE

We’ve eliminated mate-netbook from the default set up of Ubuntu MATE and
because of this the Netbook structure is not obtainable. We did this as a result of
mate-maximus, a element of mate-netbook, is the reason for some
compatibility points with shopper aspect adorned (CSD) home windows. There are nonetheless
a number of panel layouts that provide environment friendly decision use 📐 for many who want
it.

MATE Tweak has refreshed its supported for third get together compositors. Help for
Compton has been dropped, as it’s not actively maintained and
complete help for picom has been added.

will be chosen through MATE Tweak because the efficiency and compatibility of every
varies relying in your {hardware}. Some individuals select to make use of picom as a result of

I’ve up to date the Metacity/Marco (the MATE Window Supervisor) themes in Yaru to make
positive they match GNOME/CSD/Useful home windows for a constant feel and appear throughout
all window varieties 🪟 and third get together compositors like picom. I even patched how

41% much less fats 🍩

Ubuntu MATE, prefer it’s lead developer, was beginning to get a bit giant
across the mid part 😊 Throughout the improvement of twenty-two.04, the picture 📀 acquired
to 4.1GB 😮

So, we put Ubuntu MATE on a strict eating regimen 🥗 We’ve eliminated the proprietary NVIDIA
drivers from the native apt pool on the set up media and because of migrating
totally to Yaru (which now options wonderful de-duplication of icons) and likewise
eradicating our legacy themes/icons. And now the Yaru-MATE themes/icons are
utterly in upstream Yaru, we had been in a position to take away 3 snaps from the default
set up and the picture is now a way more affordable 2.7GB; 41% smaller. 🗜

That is vital to us, as a result of nearly all of our customers are in international locations
the place Web bandwidth isn’t at all times plentiful. These of you with NVIDIA GPUs,
don’t fear. If you happen to tick the third get together software program and drivers in the course of the set up
the suitable driver on your GPU will probably be downloaded and put in 👍

NVIDIA GPU homeowners ought to tick Set up third get together software program and drivers throughout set up

Whereas investigating 🕵 a bug in Xorg Server that triggered Marco (the MATE window supervisor)
to crash we found that Marco has decrease body time
latency ⏱ when utilizing Xrender with the NVIDIA proprietary drivers. We’ve
printed a PPA the place NVIDIA GPU customers can set up a model of Marco that makes use of
Xpresent for optimum efficiency ⚡

sudo apt-add-repository ppa:ubuntu-mate-dev/marco
sudo apt improve

Must you need to revert this variation you put in ppa-purge and run the
following from a terminal: sudo ppa-purge -o ubuntu-mate-dev -p marco.

enabled by default. To allow FlatHub run the next in a terminal:

We’ve additionally included snapd-desktop-integration which gives a bridge
between the consumer’s session and snapd to combine theme preferences 🎨 with
snapped apps and can even mechanically set up snapped themes 👔
All of the Yaru themes shipped in Ubuntu MATE are totally snap conscious.

purpose to be cross-distro appropriate and re-usable for any desktop setting 👌
