GNU/Linux Review: Ubuntu 16.10 Yakkety Yak
Ubuntu 16.10 Yakkety Yak desktop version is released today October 13th 2016. It is a regular release, supported for 9 months (until July 2017), bringing dual desktop environments, Unity 7 and Unity 8. This review covers 9 points, mainly about Ubuntu Yakkety bringing the new desktop environment Unity 8 on top of the new Mir Display Server plus many information you may find useful. Yakkety includes Unity 8 as a testing purpose, so every user can feel how Unity 8 is at a glance. Overall, this new Ubuntu release is already suitable for desktop use (Unity 7 only) but really not suitable for low-RAM computers. I hope this review helps everyone a lot.

Installing and Post-Installing
You can find how to install Ubuntu 16.10here and what to do after installinghere. The installation procedures is basically the same with the previous release, and the WTDAI article tells about 15-points you can do (including the installation of codecs, common desktop, communication, programming, and educational software) after having Yakkety installed.3. Hardware Compatibility
I installed Ubuntu Yakkety in the laptop (netbook) Acer Aspire One 756-967B (Intel Pentium, Intel HD Graphic, 11" LCD, 4GB RAM, 120GB SSD) with these details:WLAN: OK VGA: OK Sound: OK Touchpad: OK Monitor: OK Fn Keys: OK Suspend: OK SSD: OK Battery + charger: OK
Ubuntu 16.10 running successfully without any additional driver installation after system installation. It is a fundamentally important value for a desktop/laptop OS.4. Memory Consumption
In default mode (Unity 7), Ubuntu 16.10 eats around 1 GB of RAM when idle. It is a very huge consumption even if we compare it with our latest review inelementary OS Loki (~700 MB) ordeepin 15.3 (~500 MB) when idle. It is a big deficiency, the most minus point (technically) for Ubuntu 16.10.
And if you wonder which processes eat the most memory spaces, the answer is compiz (between 100-200 MB, may vary for another computers) followed with gnome-software (around 100 MB, also may vary) and some other processes as shown at picture below:
This memory consumption data makes me feel sad for "<= 2GB RAM" users, because it must be very heavy for them to run this Ubuntu 16.10 operating system. I don't recommend Ubuntu 16.10 Unity 7 for low-RAM computers .
Note : if you wonder how it feels running Ubuntu 16.10 on 4 GB of RAM, like mine, I tell you it feels not heavy at all. It is still smooth and stable (in less crash/hang sense). I can do any desktop task flawlessly.5. Unity 8!
Ubuntu 16.10 brings Unity 8 built-in. It's a long awaited feature, and the users now can use it directly from their desktop session. Once Yakkety installed, in the login screen, you just need to choose " Unity8 " from desktop session selection button in LightDM, and then log in. Unity 8 in Ubuntu 16.10 is brought to you by unity8-desktop-session software package ( metapackage ), as testing purpose only (in other words, Unity 8 here is not ready for daily desktop use). When you enter Unity8 session, then the desktop you will face is a black panel on top , with a vertical panel on the left edge (hidden by default, push hardly to reveal it), and a sidebar on the right edge (while you click on one item on panel tray).
Note : if you are using development version of Yakkety (e.g. beta), install unity8-desktop-session package to get the Unity 8 desktop environment.
The most noticeable appearance of Unity 8 is the Alt+Tab switcher like picture below. It's similar with the switcher in Ubuntu Touch (Ubuntu in mobile phone), while the screen covered with an blurred overlay with the application windows flipped in 3D view.
The desktop view at a glance is basically the same with Unity 7 (the normal Unity), except the user will feel some differences in the window decoration, the buttons, and even in Terminal. The Scope menu itself is still a window, not a full-screen menu like Unity 7 Dash . The Scope menu contains only few native Unity 8 applications: a web browser , a system settings , a terminal , and a " testing tool ".
Interesting to see, every single icon in tray has its own sidebar on the right edge. It is almost similar with what you see in deepin 15.3 (or even Windows 10). It is bigger and larger than drop-down menu in Unity 7.
You can not run any of X11 applications (e.g. Firefox, LibreOffice, GIMP, Shotwell, GNOME Screenshot, etc.) because Unity 8 session is not using X11 Display Server but using Mir Display Server as a replacement. Of course, while Unity 8 session is running, you computer does not run X11, but Mir. That's the reason. You need help from a special system called Libertine to run any X11 application on top of Mir in Ubuntu 16.10.
Note : X11 and Mir are software environment that acting as the display server in an operating system, in other words, the foundation of all GUI applications running on top of. Unity 8 is a new desktop environment created exclusively on top of Mir. Read more about X11 here , and Mir here
