How to Position Unity Launcher to Bottom of Screen

Only Supported on Ubuntu 16.04 +



How to Position ?

The Unity Launcher can be placed either on the left of the screen or at the bottom.

It is still not possible to move it to the right side of the screen or indeed the top of the screen.

To move the launcher to the bottom open a terminal window by pressing CTRL, ALT and T on your keyboard. Alternatively press the super key on your keyboard and searching for "term" in  the Unity Dash search bar and click the terminal icon when it appears.

Within the terminal window type the following command:

gsettings set com.canonical.Unity.Launcher launcher-position Bottom

You can type the command straight into the terminal, watch it work and then forget all about it.

To move the launcher back to the left side of the screen (because after all those years of complaining it turns out we like it where it was after all) run the following command:

gsettings set com.canonical.Unity.Launcher launcher-position Left

What Is Ubuntu ?

Ubuntu is published by Canonical Ltd, who offer commercial support. It is based on free software and named after the Southern African philosophy of ubuntu , which Canonical Ltd. suggests can be loosely translated as "humanity to others" or "I am what I am because of who we all are".

Ubuntu is the most popular operating system running in hosted environments, so–called "clouds", as it is the most popular server Linux distribution.

Development of Ubuntu is led by UK-based Canonical Ltd., a company founded by South African entrepreneur Mark Shuttleworth. Canonical generates revenue through the sale of technical support and other services related to Ubuntu. The Ubuntu project is publicly committed to the principles of open-source software development; people are encouraged to use free software, study how it works, improve upon it, and distribute it.

History and Development Process

Ubuntu is built on Debian's architecture and infrastructure, and comprises Linux server, desktop and discontinued phone and tablet operating system versions. Ubuntu releases updated versions predictably every six months, and each release receives free support for nine months (eighteen months prior to 13.04) with security fixes, high-impact bug fixes and conservative, substantially beneficial low-risk bug fixes. The first release was in October 2004.

Starting with Ubuntu 6.06, every fourth release, one release every two years, receives long-term support (LTS). Long-term support includes updates for new hardware, security patches and updates to the 'Ubuntu stack' (cloud computing infrastructure). The first LTS releases were supported for three years on the desktop and five years on the server; since Ubuntu 12.04 LTS, desktop support for LTS releases was increased to five years as well. LTS releases get regular point releases with support for new hardware and integration of all the updates published in that series to date.

Ubuntu packages are based on packages from Debian's unstable branch. Both distributions use Debian's deb package format and package management tools (e.g. APT and Ubuntu Software). Debian and Ubuntu packages are not necessarily binary compatible with each other, however; packages may need to be rebuilt from source to be used in Ubuntu. Mny Ubuntu developers are also maintainers of key packages within Debian. Ubuntu cooperates with Debian by pushing changes back to Debian, although there has been criticism that this does not happen often enough. Ian Murdock, the founder of Debian, had expressed concern about Ubuntu packages potentially diverging too far from Debian to remain compatible. Before release, packages are imported from Debian unstable continuously and merged with Ubuntu-specific modifications. One month before release, imports are frozen, and packagers then work to ensure that the frozen features interoperate well together.

Ubuntu is currently funded by Canonical Ltd. On 8 July 2005, Mark Shuttleworth and Canonical announced the creation of the Ubuntu Foundation and provided an initial funding of US$10 million. The purpose of the foundation is to ensure the support and development for all future versions of Ubuntu. Mark Shuttleworth describes the foundation goal as to ensure the continuity of the Ubuntu project.

On 12 March 2009, Ubuntu announced developer support for 3rd-party cloud management platforms, such as those used at Amazon EC2.

Unity has become the default GUI for Ubuntu Desktop, although following the release of Ubuntu 17.10 it will move to the GNOME 3 desktop instead as work on Unity ends. However, a community-driven fork of Unity 8, called Yunit, has been created to continue the development of Unity.[non-primary source needed] Shuttleworth wrote on 8 April 2017, "We will invest in Ubuntu GNOME with the intent of delivering a fantastic all-GNOME desktop. We're helping the Ubuntu GNOME team, not creating something different or competitive with that effort. While I am passionate about the design ideas in Unity, and hope GNOME may be more open to them now, I think we should respect the GNOME design leadership by delivering GNOME the way GNOME wants it delivered. Our role in that, as usual, will be to make sure that upgrades, integration, security, performance and the full experience are fantastic." Shuttleworth also mentioned that Canonical will cease development for Ubuntu Phone, Tablet, and convergence

Features

A default installation of Ubuntu contains a wide range of software that includes LibreOffice, Firefox, Thunderbird, Transmission, and several lightweight games such as Sudoku and chess. Many additional software packages are accessible from the built in Ubuntu Software Center as well as any other APT-based package management tools. Many additional software packages, such as Evolution, GIMP, Pidgin, and Synaptic, that are no longer installed by default, are still accessible in the repositories, installable with the built in Ubuntu Software Center; or by any other APT-based package management tool and Snappy.

Ubuntu operates under the GNU General Public License (GPL) and all of the application software installed by default is free software. In addition, Ubuntu installs some hardware drivers that are available only in binary format, but such packages are clearly marked in the restricted component. Intuitive dash interface making it easy to find applications, files and other things with a great set of keyboard shortcuts.

Security

Ubuntu's goal is to be secure "out-of-the box". By default, the user's programs run with low privileges and cannot corrupt the operating system or other users' files. For increased security, the sudo tool is used to assign temporary privileges for performing administrative tasks, which allows the root account to remain locked and helps prevent inexperienced users from inadvertently making catastrophic system changes or opening security holes. PolicyKit is also being widely implemented into the desktop. Most network ports are closed by default to prevent hacking. A built-in firewall allows end-users who install network servers to control access. A GUI (GUI for Uncomplicated Firewall) is available to configure it. Ubuntu compiles its packages using GCC features such as PIE and buffer overflow protection to harden its software. These extra features greatly increase security at the performance expense of 1% in 32-bit and 0.01% in 64-bit.

Ubuntu also supports full disk encryption as well as encryption of the home and Private directories.

Installation

Ubuntu running on the Nexus S, a smartphone that ran Android prior to Ubuntu The system requirements vary among Ubuntu products. For the Ubuntu desktop release 16.04 LTS, a PC with at least 2 GHz dual-core processor, 2 GB of RAM and 25 GB of free disk space is recommended. For less powerful computers, there are other Ubuntu distributions such as Lubuntu and Xubuntu. Since version 12.04, Ubuntu supports the ARM architecture.Ubuntu is also available on Power,older PowerPC architecture was at one point unofficial supported, and now newer Power Architecture CPUs (POWER8) are supported.

Live images are the typical way for users to assess and subsequently install Ubuntu. These can be downloaded as a disk image (.iso) and subsequently burnt to a DVD and booted, or run via UNetbootin directly from a USB drive (making, respectively, a live DVD or live USB medium). Running Ubuntu in this way is typically slower than running it from a hard drive, but does not alter the computer unless specifically instructed by the user. If the user chooses to boot the live image rather than execute an installer at boot time, there is still the option to then use an installer called Ubiquity to install Ubuntu once booted into the live environment. Disk images of all current and past versions are available for download at the Ubuntu web site. Various third-party programs such as remastersys and Reconstructor are available to create customized copies of the Ubuntu Live DVDs (or CDs). "Minimal CDs" are available (for server use) that fit on a CD.

Additionally, USB flash drive installations can be used to boot Ubuntu and Kubuntu in a way that allows permanent saving of user settings and portability of the USB-installed system between physical machines (however, the computers' BIOS must support booting from USB). In newer versions of Ubuntu, the Ubuntu Live USB creator can be used to install Ubuntu on a USB drive (with or without a live CD or DVD). Creating a bootable USB drive with persistence is as simple as dragging a slider to determine how much space to reserve for persistence; for this, Ubuntu employs casper.

The desktop edition can also be installed using the Netboot image (a.k.a. netboot tarball) which uses the debian-installer and allows certain specialist installations of Ubuntu: setting up automated deployments, upgrading from older installations without network access, LVM or RAID partitioning, installs on systems with less than about 256 MB of RAM (although low-memory systems may not be able to run a full desktop environment reasonably).
