In particular, there are 2 shortcuts added to Ubuntu 12.04:

If you press the Windows logo for a long time, the list of keyboard shortcuts shown in the following figure will be displayed on the desktop.

Press the Alt key to display HUD

HUD:Head Up Display, head-up display, is a flight aid widely used in aircraft at present. Heads-up means that the pilot does not need to bow his head to see the important information he needs)

III. Noteworthy changes in Ubuntu 12.04

A

Ubuntu 12.04 comes with the latest version of Gwibber 3.4. Gwibber already supports Twitter, Facebook, Identi.ca, Sina Weibo and Sohu Weibo. To add Sina Weibo and Sohu Weibo, you also need to install plug-ins:

Sudo apt-get install gwibber-service-sina # Sina Weibo sudo apt-get install gwibber-service-sohu # Sohu Weibo

B

Ubuntu One control panel and client rewrite using QT

C

Unity initiator settings are added in system Settings-appearance, but the functionality is slightly inadequate with the special Unity setup tool we described above.

D:Landscape client

Landscape client is an easy-to-use commercial system management and monitoring service provided by Canonical, which can help administrators manage multiple machines effectively.

For more information, please click on the following link: https://landscape.canonical.com

E: privacy feature

Click "system Settings-Privacy" to set whether to turn on "record activity", such as files, applications, diagnostics, etc.

You can also click "recent Project" to carry out "record cleaning", which can better help us to protect our privacy.

F: "close", "maximize" button, "separate".

Personally, I think this is a painful change, as shown in the following figure:

Tip: if you feel that the mouse has encountered misfortune here and "travel" back and forth, you can use the following shortcut keys to minimize the pain caused by the change of egg pain:

Alt+ Spacebar: pop up the title bar control menu, and then press the face key:

X-maximize / minimize

N-minimization

C-closes the current window

The concept of "desktop cloud" embodied in F:Unity

G:Ubuntu for Android

Canonical's "Ubuntu for Android" is to seamlessly integrate the entire Ubuntu desktop system into Android, treating the Android phone as a portable computer.

Project home page: http://www.ubuntu.com/devices/android

H:Ubuntu TV

Ubuntu TV integrates broadcast and online services to search, watch, record and play videos.

Information:

OMGUBUNTU describes how to install Ubuntu TV@ http://www.omgubuntu.co.uk/2012/01/how-to-install-ubuntu-tv-right-now-via-ppa through PPA

IMCN: explain Ubuntu TV-TV for human beings in detail

I just want to say: Canonical has laid a "cloud network" on the desktop and server, and the desktop has made efforts to integrate cloud services (but not much is available locally in China, but this idea is worth learning), and the server has also taken the lead in cloud computers.

IV. Lens

This aspect is no longer covered, you can refer to the article: Ubuntu Unity Lens and the related links below the article.

5. Application indicator (Indicator)

Such as:

-Weather indicator:

Sudo apt-get install indicator-weather- system load indicator:

Sudo apt-get install indicator-multiload-Psensor (graphical interface temperature monitor on Linux):

Sudo apt-get install psensor-Ubuntu One indicator

Sudo add-apt-repository ppa:rye/ubuntuone-extras

Sudo apt-get update

Sudo apt-get install indicator-ubuntuone

……

To name a few, you can refer to the articles on other brothers' blogs and install the indicators you need. You can also search for the keyword "indicator" in the Ubuntu Software Center to find relevant results. I remember that at the Ubuntu developer conference held in the second half of last year, there was news that the Ubuntu Software Center would add Indicator and Lens software categories to the new version.

Recommendation: Askubuntu Indicator collects posts

VI. Other system settings

A: install Gdebi

If you do not install Gdebi, directly double-click the downloaded deb format package, the system will call the Ubuntu Software Center to install, which is very bad. Of course, instead of installing Gdebi, you can use the command dpkg to install the deb package.

Sudo apt-get install gdebi # install Gdebi

Or

Dpkg-I

# install the downloaded deb package using dpkg in the terminal

B, right-click "Open in Terminal"

Sudo apt-get install nautilus-open-terminal for more extensions to the Nautilus file manager, you can use the Tab completion command

Sudo apt-get install nautilus- (Tab completion, see more extensions) C: install the Linux Deepin screenshot tool and Deepin software center

-Linux Deepin screenshot tool

Wget packages.linuxdeepin.com/deepin/pool/main/d/deepin-scrot/deepin-scrot_2.0-0deepin_all.deb

Sudo dpkg-I deepin-scrot*

After installation, you need to bind to enable the depth screenshot tool shortcut key Ctrl+Alt+A

-Linux Deepin Software Center

This depends on the aria2 download command, let's install it first:

Sudo apt-get install aria2

Next, download and install the Deep Software Center:

Wget http://packages.linuxdeepin.com/deepin/pool/main/d/deepin-software-center/deepin-software-center_2.1.2deepin1_all.deb

Sudo dpkg-I deepin-software-center*

Tip: if you encounter problems such as insufficient dependency during the installation of the software, you can first use the following command

Sudo apt-get-f install

D: Chinese input method

Ubuntu 12.04 is equipped with Ibus input method by default, with "Pinyin" and "Bopomofo" by default. In fact, there is something sharper:

Sudo apt-get install ibus-googlepinyin # Google Pinyin input method

Sudo apt-get install ibus-sunpinyin # Sun Pinyin input method

Of course, we can also choose SCIM and Fcitx.

Sudo apt-get install scim # install SCIM

Sudo apt-get install fcitx # install Little Penguin input method

Scim is once a popular Chinese input method. I used it a few days ago, and I feel very good.

Fcitx comes with Google Pinyin, Wubi font, Pinyin and double spelling. Here are other input methods of Fcitx:

Sudo apt-get install fcitx-sunpinyin # adds Sun Pinyin input method to Fcitx

Sudo apt-get install fcitx-table-wbpy # five-stroke pinyin, more can be completed by Tab

Input method switching

Method 1: click "system Settings-language support-Keyboard input Mode system", select the installed input method as the default enabled input method, and then log out of the system to make it effective

Method 2: enter the following command at the terminal

After im-switch enters the above command, it will pop up the following dialog box, select the appropriate input method, click "OK", and log out of the system, effective immediately.

F: audio and video decoder and Adobe Falsh player

When playing audio, video and opening web video, you will be prompted that the relevant plug-ins are missing, just click search for installation.

7. GNOME Shell

GNOME Shell version 3.4.0 is currently available in the Ubuntu 12.04 source. You can install it with the following command:

Sudo apt-get install gnome-shell

With regard to GNOME Shell, the detailed configuration is not discussed in detail here. You can refer to the GNOME Shell configuration article when Ubuntu 11.10 was released. Here are a few common questions for your reference:

A-Ctrl+Alt+T, unable to enable terminal quickly

Open "system Settings-Keyboard-launcher" and see if there is an option to start the terminal. If not, click "Custom Shortcut", the command is set to "x-terminal-emulator" (no quotes), and the shortcut key is set to Ctrl+Alt+T.

Shell theme cannot be used in B-Advanced Settings

Although the User theme extension for GNOME Shell is installed, the Shell theme cannot be selected in Gnome tweak tool. You can use dconf-editor to set it up.

Sudo apt-get install dconf-tools # installation

Then, press Alt+F2, type dconf-editor, open org- > gnome- > shell- > extensions- > user-theme, and set the key to the name of the topic you have installed.

Or

Use gsettings to set it directly in the terminal:

Gsettings set org.gnome.shell.extensions.user-theme name Aqua prompts to replace Aqua with the theme file that you have installed.

GNOME Shell extension official site: http://extensions.gnome.org

VIII. Installation of other desktop environments

Previously, I had some misunderstandings about this installation, always installing things like kubuntu-desktop, which installed not only the KDE desktop environment, but also most of the software under Kubuntu. In fact, we can just install KDE. The size of the installation is not generally reduced in this way.

LXDE:

Sudo apt-get install lxdeXFCE:

Sudo apt-get install xfce4
