Unity (user interface)From Wikipedia, the free encyclopedia

Unity is a shell interface for the GNOME desktop

environment developed by Canonical Ltd. for its Ubuntu

operating system. Unity debuted in the netbook edition of

Ubuntu 10.10. It was initially designed to make more

efficient use of space given the limited screen size of

netbooks, including, forexample, a vertical application

switcher[4] called the launcher.[5] Unlike GNOME, KDE

Software Compilation, Xfce, or LXDE, Unity is not a

collection of applications but is designed to use existing

programs.[6]

Unity is part of the Ayatana project, an initiative to

improve the user experience within Ubuntu.[7] In addition

to Unity, there are Application Indicators and otherprojects such as MeMenu, the notification system and

the application NotifyOSD gathered.

Unity 2D showing the ability to run

alongside different window managers and

desktop environments

On January 2, 2013 Canonical announced a smartphone variant of

Unity.[14]

Unity 2D

Canonical maintained two discrete versions of Unity, which are

visually almost indistinguishable but technically different.

Unity is written as a plugin for Compiz[15] and is written in the

programming languages C++ and Vala, and uses an uncommon

OpenGL toolkit called Nux. Being a plugin for Compiz gives

Unity GPU-accelerated performance on compatible systems.

Unity 2D is a set of individual applications[16] developed for

environments that Compiz does not run on, such as when

graphics card does not support OpenGL. They are written in the

GUI building language QML from the widespread Qt

framework.[17] By default Unity 2D uses the Metacity windowmanager[16] but can also use accelerated window managers like

Compiz or KWin. In Ubuntu 11.10, Unity 2D uses Metacity's

XRender-based compositor to achieve transparency

effects.[citation needed] Starting with Ubuntu 11.10, Unity 2D

replaced the classic GNOME Panel as the fall-back for users

whose hardware cannot run the Compiz version of Unity.[18]

Unity 2D was discontinued for the release of Ubuntu 12.10 in October 2012, as the 3D version became more

capable of running on lower-powered hardware.

Availability

As Unity and the supporting Ayatana projects[20] are developed primarily for Ubuntu, Ubuntu is the first to offer

new versions.

Outside of Ubuntu, other Linux distributors have tried to pick up Ayatana, with varying success. The Ayatana

components require modification of other applications, which increases the complexity for adoption by others.

Arch Linux offers many Ayatana components, including Unity and Unity 2D, via an unofficial repository

or through the AUR[21]

Fedora does not offer Unity in its default repositories because Unity requires unsupported patches to

GTK.[22] However Unity has been ported to Fedora 17 and can be installed through a branch in the

openSUSE repositories where the patches are applied.[23][24]

Frugalware had adopted Ayatana, including Unity and Unity 2D, as part of the development branch for

an upcoming Frugalware release but the project is no longer maintained. [25]

openSUSE offers many Ayatana components for GNOME.[26] After the packager abandoned the

project because of problems with the then-current version of Compiz,[27] new developers picked up the

task and provide packages for openSUSE 12.2 (along with versions for Arch Linux and Fedora 17). [24]

Leeenux Linux has editions with Unity 2D, in v5 and v6.[28]

Development

Ubuntu originally used the full GNOME desktop environment; Ubuntu founder Mark Shuttleworth cited

philosophical differences with the GNOME team over the user experience to explain why Ubuntu would use

Unity as the default user interface instead of GNOME Shell, beginning April 2011, with Ubuntu 11.04 (Natty

Narwhal).[29]

In November 2010, Ubuntu Community Manager Jono Bacon explained that Ubuntu will continue to ship theGNOME stack, GNOME applications, and optimize Ubuntu for GNOME. The only difference, he wrote,

would be that Unity is a different shell for GNOME.[30]

Canonical announced it had engineered Unity for desktop computers as well and would make Unity the default

shell for Ubuntu in version 11.04.[31]

GNOME Shell was not included in Ubuntu 11.04 Natty Narwhal because work on it was not completed at the

time 11.04 was frozen, but is available from a PPA,[32] and is available in Ubuntu 11.10 and later releases,

through the official repositories.[33]

In November 2010, Mark Shuttleworth announced the intention to eventually run Unity on Wayland instead of

the currently used X window system,[34] although this plan has since been dropped, replacing Wayland with Mir

forUnityNext.[35]

In December 2010, some users requested that the Unity launcher (or dock) be movable from the left to other

sides of the screen, but Mark Shuttleworth stated in reply, I'm afraid that won't work with our broader design

goals, so we won't implement that. We want the launcher always close to the Ubuntu button.[36] However, with

Ubuntu 11.10, the Ubuntu button has been moved into the launcher, rendering this argument invalid. A third-

party plugin that moves Unity 3D's launcher to the bottom is available.[37]

As of 2010 the Unity shell interface developers use a toolkit called Nux instead of Clutter.[38] Unity is a plugin

of the Compiz window manager,[15] which Canonical states is faster than Mutter,[39] the window manager for

which GNOME Shell is a plugin.

On 14 January 2011 Canonical also released a technical preview of a 2D version of Unity based on Qt and

written in QML.[17] Unity-2D was not shipped on the Ubuntu 11.04 CD, instead the classic GNOME desktop

was the fall-back for hardware that could not run Unity.[40][41]

In March 2011 public indications emerged of friction between Canonical (and its development of Unity) and theGNOME developers. As part of Unity development Ubuntu developers had submitted API coding for inclusion

in Gnome as an external dependency. According to Dave Neary, ... an external dependency is a non-GNOME

module which is a dependency of a package contained in one of the GNOME module sets, and the reasons

why libappindicator was not accepted as an external dependency are that ... it does not fit that definition, it has

... duplicate functionality with libnotify, (the current Gnome Shell default) and its CLA does not meet current

GNOME policy.[42] Mark Shuttleworth responded,

This is a critical juncture for the leadership of Gnome. I'll state plainly that I feel the long tail of

good-hearted contributors to Gnome and Gnome applications are being let down by a

decision-making process that has let competitive dynamics diminish the scope of Gnome itself.

Ideas that are not generated 'at the core' have to fight incredibly and unnecessarily hard to get

oxygen... getting room for ideas to be explored should not feel like a frontal assault on a

machine gun post. This is no way to lead a project. This is a recipe for a project that loses great

people to environments that are more open to different ways of seeing the world ... Embracing

those other ideas and allowing them to compete happily and healthily is the only way to keep

the innovation they bring inside your brand. Otherwise, you're doomed to watching them

innovate and then having to relayout your own efforts to keep up, badmouthing them in the

process. We started this with a strong, clear statement: Unity is a shell for Gnome. Now

Gnome leadership have to decide if they want the fruit of that competition to be an asset to

Gnome, or not.[43][44][45]

In April 2011 Mark Shuttleworth announced that Ubuntu 11.10 Oneiric Ocelot would not include the classic

GNOME desktop as a fall-back to Unity, unlike Ubuntu 11.04 Natty Narwhal. Instead Ubuntu 11.10 used the

Qt-based Unity 2D for users whose hardware cannot support the 3D version.[18][46] However, the classic

GNOME desktop (GNOME Panel) can be installed separately in Ubuntu 11.10 and 12.04 throughgnome-

anel, a package in the Ubuntu repositories.[47]

At the November 2011 Ubuntu Developer Summit it was announced

that Unity for Ubuntu 12.04 would include non-re-enabling the

systray, better application integration, and the ability to drag lenses

onto the launcher and that the 2D version of Unity would use the

same decoration buttons as the 3D version.[48]

During the planning conference for Ubuntu 12.10 it was announced

that Unity 2D will likely be dropped in favour of making Unity 3D run

better on lower end hardware.[19]

In July 2012 at OSCON, Shuttleworth explained some of the

historical reasoning behind Unity's development. The initial decision to

develop a new interface in 2008 was driven by a desire to innovate and to pass Microsoft and Apple in userexperience. This meant a family of unified interfaces that could be used across many device form factors,

including desktop, laptop, tablet, smart phones and TV. Shuttleworth said "The old desktop would force your

tablet or your phone into all kinds of crazy of funny postures. So we said: Screw it. Were going to move the

desktop to where it needs to be for the future. [This] turned out to be a deeply unpopular process.[49]

Initial testing of Unity during development was done in a laboratory setting and showed the success of the

interface, despite public opposition. Real world shipping return rates also indicated acceptance. Shuttleworth

explained, ASUS ran an experiment where they shipped half a million [Unity netbooks and laptops] to

Germany. Not an easy market. And the return rates on Ubuntu were exactly the same as the return rates on

Windows. Which is the key indicator for OEMs who are looking to do this.[49]

Microsoft's development of Windows 8 and its Metro interface became an additional incentive for Unity

development, as Shuttleworth explained, we [had to move] our desktop because if we didnt wed end up

where Windows 8 is. [In Windows 8] you have this shiny tablet interface, and you sit and you use then you

press the wrong button then it slaps you in the face and Windows 7 is back. And then you think OK, this is

familiar, so youre kind of getting into it and whack [Windows 8 is back].[49]

In March 2013, the plan to use the Mir display server was announced for future development of Unity, in place

of the previously announced Wayland/Weston.[35]

Unity has received mixed reviews. Its design and deployment has been controversial with some software

reviewers finding fault with its implementation and limitations, while other reviewers have found Unity an

improvement over GNOME 2 with the potential to improve over time.[50][51][52][53][54] With the release of

Ubuntu 12.04 on 26 April 2012 reviewers seemed more positive about Unity as the interface matured.

2010

In reviewing an alpha version of Unity shortly after it was unveiled in the summer of 2010, Ryan Paul of ArsTechnica noted problems figuring out how to launch additional applications that are not on the dock bar. He also

mentioned a number of bugs, including the inability to track which applications are open and other window

management difficulties. He remarked that many of these were probably due to the early stage in the

development process and expected them to be resolved with time. Paul concluded positively, Our test of the

Unity prototype leads us to believe that the project has considerable potential and could bring a lot of value to

the Ubuntu Netbook Edition. Its unique visual style melds beautifully with Ubuntu's new default theme and its

underlying interaction model seems compelling and well-suited for small screens.[50][51]

In an extensive review of Ubuntu 10.10 shortly after its release in October 2010, Ryan Paul of Ars Technica

made further observations on Unity, noting that "Unity is highly ambitious and offers a substantially differentcomputing experience than the conventional Ubuntu desktop. He concluded that "The [application] selectors

are visually appealing, but they are easily the weakest part of the Unity user experience. The poor performance

significantly detracts from their value in day-to-day use and the lack of actual file management functionality

largely renders the file selector useless. The underlying concepts behind their design are good, however, and

they have the potential to be much more valuable in the future as unity matures.[52][53]

2011

In March 2011 writer Benjamin Humphrey of OMG Ubuntu criticized the development version of Unity thenbeing tested for Ubuntu 11.04 on a number of grounds, including a development process that is divorced from

user experiences, the lack of response to user feedback, ... the seemingly unbelievable lack of communication

the design team has, and a user interface he described as ... cluttered and inconsistent. Overall, however, he

concluded that ... Unity is not all bad ... While a number of the concepts in Unity may be flawed from a design

point of view, the actual idea itself is not, and Canonical deserve applause for trying to jump start the stagnant

open source desktop with Unity when the alternatives do not evoke confidence.[51]

On 14 April 2011 Ryan Paul of Ars Technica reviewed Unity as implemented in Ubuntu 11.04 beta, just two

weeks before its stable release. At that time he reported that Unity was on track for inclusion in Natty Narwhal,

despite the ambitious development schedule. He indicated, ... close attention to detail shines through in manyaspects of Unity. The menubar is clean and highly functional. The sidebar dock is visually appealing and has

excellent default behaviors for automatic hiding. He did note that the interface still has some weak points,

especially difficulties browsing for applications not on the dock, as well as switching between application

categories. He singled out ... random packages from the repositories, which are presented as applications that

are available for installation in the launcher, are distracting and largely superfluous. Paul concluded, There is

still a lot of room for improvement, but Unity is arguably a strong improvement over the conventional GNOME

2.x environment for day-to-day use. The breadth of the changes may be disorienting for some users, but most

will like what they see when Unity lands on their desktop at the end of the month.[53] Two weeks later he

added the lack of configurability to his criticisms.[55] In a very detailed assessment of Ubuntu 11.04 and Unity

published on 12 May 2011, Ryan Paul further concluded Unity was a positive development for Ubuntu, but that

more development must be invested to make it work right. He wrote, They have done some incredibly

impressive work so far and have delivered a desktop that is suitable for day-to-day use, but it is still very far

from fulfilling its full potential.[56]

On 25 April 2011, the eve of the release of Ubuntu 11.04, reviewer Matt Hartley ofIT Managementcriticized

Unity, saying that the "dumbing down of the Linux desktop environment is bordering on insane.[57]

Reviewer Joey Sneddon ofOMG Ubuntu was more positive about Unity in his review of Ubuntu 11.04,

encouraging users, Sure it's different but different doesn't mean bad; the best thing to do is to give it a

chance. He concluded that Unity on the desktop makes "better use of screen space, intuitive interface layouts

and, most importantly, making a desktop that works for the user and not in spite of them.[58]

Following the release of Ubuntu 11.04 Canonical Ltd. founder Mark Shuttleworth indicated that while he was

generally happy with the implementation of Unity, he felt that there was room for improvement. Shuttleworth

said, I recognise there are issues, and I would not be satisfied unless we fixed many of them in 11.10 ... Unity

was the best option for the average user upgrading or installing. There are LOTS of people for whom it isn't the

best, but we had to choose a default position ... It's by no means perfect, and it would be egotistical to suggest

otherwise... I think the bulk of it has worked out fantastically both at an engineering level (Compiz, Nux) and

in the user experience.[59]

In reviewing Unity in Ubuntu 11.04 on 9 May 2011, Jesse Smith of Distrowatch criticized its lack of

customization, menu handling and Unity hardware requirements, saying, There's really nothing here whichshould demand 3D acceleration. He also noted that The layout doesn't translate well to large screens or

multiple-screen systems.[60] Jack M. Germain ofLinux Insiderreviewed Unity on 11 May 2011, indicating

strong dislike for it, saying, Put me in the Hate It category and indicating that as development has proceeded

he likes it less and less.[61]

More criticism appeared after the release of Ubuntu 11.10. In November 2011 Robert Storey writing in

DistroWatch noted that developer work on Unity is now taking up so much time that little is getting done on

outstanding Ubuntu bugs, resulting in a distribution that is not as stable or as fast as it should be. Storey

concluded "Perhaps it would be worth putting up with the bugs if Unity was the greatest thing since sliced

bread something wonderful that is going to revolutionize desktop computing. But it's not. I tried Unity, andit's kind of cute, but nothing to write home about.[62]

In November 2011 OMG! Ubuntu! conducted a non-scientific poll that asked its readers "which Desktop

Environment Are You Using in Ubuntu 11.10?". Of the 15,988 votes cast 46.78% indicated that they were

using Unity over GNOME Shell (28.42%), Xfce (7.58%), KDE (6.92%) and LXDE (2.7%).[63]

Developers of Linux distributions based upon Ubuntu have also weighed in on the introduction of Unity in early

2011, when Unity was in its infancy. Some have been critical, including two distributions who base their criticism

on usability testing. Marco Ghirlanda, the lead developer of the audio- and video-centric ArtistX, stated, When

I tried Unity on computer illiterates, they were less productive and took ages to understand the concepts behindit. When I show them how to use it, they said that it is pretty to see but hard to use. Stephen Ewen, the lead

developer for UberStudent, an Ubuntu-based Linux distribution for higher education and college-bound high

school students, stated, Unity's design decreases both visual and functional accessibility, which tabulates to

decreased productivity. Ewen also criticized Unity's menu scheme as much less accessible than on GNOME 2,

which he said, means that the brain cannot map as quickly to program categories and subcategories, which

again means further decreased productivity.[64]

2012

With the release of Ubuntu 12.04 on 26 April 2012 reviewers seemed more positive about Unity as the

interface matured. Writing about Ubuntu 12.04 after its release, Jesse Smith of DistroWatch said Over the past

two years many people, myself included, have questioned Ubuntu's direction. The developers have tackled a

number of projects, some of which seemed misguided at the time, Unity being chief amongst them. However,

with the release of 12.04 LTS I feel that the various puzzle pieces, which may have been underwhelming

individually, have come together to form a whole, clear picture. However he also concluded While I think

Unity has grown to maturity, I found that its lack of flexibility bothered me.[65]

In June 2012 TechRepublic writer Jack Wallen, who had been very critical of early versions of Unity said Ive

noticed something lately. Since Ubuntu 12.04 was released, and I migrated over from Linux Mint, Im working

much more efficiently. This isnt really so much a surprise to me, but to many of the detractors who assume

Unity a very unproductive desktop... well, I can officially say they are wrong... I realize that many people outthere have spurned Unity (I was one of them for a long time), but the more I use it, the more I realize that

Canonical really did their homework on how to help end users more efficiently interact with their computers.

Change is hard period. For many, the idea of change is such a painful notion they wind up missing out on some

incredible advancements. Unity is one such advancement.[66]

Ryan Paul of Ars Technica was more negative in his review of Ubuntu 12.04. While he praised Unity's maturity

in this release he also wrote: Although Unity's quality has grown to the point where it fulfills our expectations,

the user experience still falls short in a number of ways. We identified several key weaknesses in our last two

Ubuntu reviews, some of which still haven't been addressed yet. These issues still detract from Unity's

predictability and ease of use.[67]

Amazon privacy controversy

Ubuntu 12.10 brought numerous aesthetic changes to Unity, adding animations and a new previews feature.

Much criticism, however, was directed towards the new shopping lens feature, which integrates Amazon search

into the dash's home lens.[68] As the previous home lens is used primarily to search for programs and files and

musics on a user's machine, not online, users were concerned about Unity sending search queries to Amazon

which were intended only for local content, citing an invasion of privacy. The constant returning of unwanted

(and often unrelated) product suggestions that translates into monetary gain for Canonical was compared to be a

form of built-in advertising. Mark Shuttleworth defended the feature, posting that "the Home Lens of the Dash

should let you find *anything* anywhere"[69] and noting that there was an option to disable the Dash's online

features in Ubuntu's settings app. He also stated that Canonical would anonymize all data before sending it to

Amazon, though Canonical themselves would be able to determine its true origin. This was insufficient to

alleviate the worries of many users, who complained that having the feature activated by default (as opposed to

an opt-in mechanism) could result in many being unaware of the implications of searching in the dash.[70]

Shuttleworth also announced that Canonical would gain affiliate revenue from Amazon for any purchases made

based on Unity search suggestions; many users considered this evidence that Canonical were simply using the

feature as a way to make money without consideration for the privacy of users.[71]

Canonical was required by EU Law to introduce a legal notice into the dash, informing users of the sharing of

their data. This was added before the final release of Ubuntu 12.10.[72]

None of Ubuntu's official derivatives (Kubuntu, Xubuntu, Lubuntu, etc.) include the feature or any variation of it.

In reviewing Ubuntu 12.10 at the end of October 2012 for DistroWatch, Jesse Smith raised concerns about the

Amazon shopping lens, saying, it has raised a number of privacy concerns in the community and, looking over

Ubuntu's legal notice about privacy does not provide any reassurance. The notice informs us Canonical reserves

the right to share our keystrokes, search terms and IP address with a number of third parties, includingFacebook, Twitter, Amazon and the BBC. This feature is enabled by default, but can be turned off through the

distribution's settings panel.[73]

9/12

In early November 2012 the Electronic Frontier Foundation made a statement on the shopping lens issue,

Technically, when you search for something in Dash, your computer makes a secure HTTPS connection to

productsearch.ubuntu.com, sending along your search query and your IP address. If it returns Amazon products

to display, your computer then insecurely loads the product images from Amazon's server over HTTP. This

means that a passive eavesdropper, such as someone sharing a wireless network with you, will be able to get a

good idea of what you're searching for on your own computer based on Amazon product images. It's a major

privacy problem if you can't find things on your own computer without broadcasting what you're looking for to

the world.[74]
