This article mainly introduces the use of Ubuntu 12.04, the article is very detailed, has a certain reference value, interested friends must read it!

Ubuntu releases a new version every six months, and the upcoming version of Ubuntu 12.04 is codenamed "Precise Pangolin" and interpreted as "accurate pangolin" in Chinese (there may be a better translation). At the same time, Ubuntu 12.04 is also a LTS version, and its official version will normally be released in mid-late April 2012. This new version is a long-term support version, it is said that both the desktop version and the server version have been supported for as long as 5 years, and everyone has high expectations for this. According to the information from famous foreign bloggers, the release date of Ubuntu 12.04 (Precise Pangolin) remains the same and will arrive on April 26th, 2012. are you very concerned about the new development of this new version? Let's take a look at this album!

In terms of schedule, Ubuntu 12.04 plans to release Beta 1 and 2 beta versions on March 1 and 22, RC candidate version on April 19, and official version on April 26, 2012. in addition, Ubuntu 12.04 as a LTS version, Ubuntu 12.04 * * version Ubuntu 12.04.1 will be released on April 16 next year; the second version will be released on February 7, 2013. The third version will be released sometime in the summer of 2013; * one will be launched on January 24, 2014.

Since February 2012, Ubuntu has released two Alpha versions, Ubuntu 12.04 Alpha 1 and Ubuntu 12.04 Alpha 2. And, since the Linux system kernel has been upgraded to Linux 3.2, Ubuntu 12.04 Alpha 2 has also been upgraded to the * kernel version. It is understood that Linux Kernel version 3.2 kernel has brought many new features, such as EXT4 file system supports 4KB-1MB block size to better support large files, CPU time limit can be set in thread scheduler, Btrfs file system is greatly improved, Device Mapper simplified configuration, Hexagon architecture support and so on.

Recently, Ubuntu released a new version of Ubuntu 12.04 Beta 2. The editor has experienced the most eye-catching highlights and now shares it with all netizens. Ubuntu 12.04 does not abandon the controversial Unity desktop environment and highlights the touch screen style of mobile phones. The move also further demonstrates Ubuntu's determination to enter the mobile terminal market.

With the release of 12.04, some new features will take Unity to the next level. While these new features won't convince everyone to use the Unity desktop, they have at least aroused a lot of interest in trying Ubuntu again. Let's take a look at these new features.

Now that Ubuntu's ISO installation files have reached 750MB, a CD CD won't fit at all, so users have to consider using DVD and USB drives to load the installation files. Starting with Ubuntu 12.04, the default 64-bit image download is not the previous 32-bit download. This puts forward higher requirements for the hardware conditions of the user's computer. However, this is also the result of keeping pace with the times.

64-bit software and hardware have been widely used, but 32-bit is still popular because of usage habits, compatibility and so on. Canonical has always recommended Ubuntu users to use 32-bit version. With Precise Pangolin Ubuntu 12.04 LTS approaching, 64-bit is finally expected to become the recommended version. In this album, let's take a look at the performance differences between the two different versions of Ubuntu 12.04, and see if the 64-bit version is worth looking forward to.

The controversial Unity user interface of Ubuntu 12.04 has made a number of improvements, including configuration settings, Nautilus shortcut menus, window refinement, right-click access to shortcut menu items, and so on. The Unity Welcome Interface (via LightDM) is used as a lock screen interface, and other things such as information prompts may also appear in the welcome interface.

From Ubuntu 12.04, you will not be able to start the entire system tray (whitelist all), only the applications specified in the whitelist will be allowed; add better Unity applications to port quicklist, badge, etc.; you can drag lens directly to the Unity initiator; Unity 2D will use the Unity window decoration button to * * convert the window. At the same time, Overlay Scroolbar will be applied to xul (Firefox,Thunderbird), vcl (Libreoffice), swing (Java) and nux. Wayland may be introduced in Ubuntu 12.04, but the task is at a lower level, and there will be some work involving wayland.

Privacy setting, this function is not related to system security, it is just an enhancement in privacy protection. As you know, both Unity and Gnome 3 have powerful desktop search tools. The problem now is that all files can be searched. So if someone has access to your account, he can search for any file. In Ubuntu 12.04, you can specify which files and folders are excluded from file search.

Video filtering (Video Lens), Ubuntu's Unity Lens provides a filtering channel that can only look at the type of media you want to watch. Unity has already provided Audio Lens, and now Video Lens has been added. This is very important for users who often deal with media files, it allows you to easily search Youtue,Amazon,Shows,ABC iView,TED and so on. MyUnity, which is a configuration tool for Unity. It can be used to configure desktops, control panels, launchers, etc.

In addition, Ubuntu 12.04 will have a new lock screen that will look a lot like LightDM login manager? In fact, it is the LightDM login manager. Yes, you heard right. In yesterday's Ubuntu 12.04 update, Canonical abandoned the traditional lock screen and replaced it with the login screen.

As the official release of Ubuntu 12.04 approaches, the default wallpaper for Ubuntu 12.04 has been released. And the CD packaging cover of Ubuntu 12.04 also met with you recently, with a mysterious purple background, which is quite concise and meaningful. Mark Shuttleworth, founder of Canonical, said on his blog that the release of Ubuntu 12.04 LTS is an important milestone, thanks to users' long-term support.

Shuttleworth said that Ubuntu 12.04 LTS*** brings true desktop user experience innovation to enterprise-certified free software platforms. Mission accomplished (job done) cannot be said yet, but it is a milestone. This achievement was achieved with the cooperation of the community and high-end projects. He said that today's LTS world is better than 10.04 Unit for both core developers and newbies.

Although Ubuntu has recently made a lot of moves in the preparation and promotion of the new version, it also has to face some controversy and doubts in the open source community. When it comes to contributing to the Linux community, a white paper released by LinuxFoundation in March listed the top 20 companies that contributed to the community. On this list, you can find the names of the Linux systems that your notes are familiar with: Novell (now SUSE), Red Hat, and The Linux Foundation. There is no Ubuntu? Yes, look for it again, there is still no Ubantu! If you take a closer look, Microsoft is on the list. Is Microsoft's contribution to the Linux community even greater than that of Ubuntu? Mark Shuttleworth, the founder of Ubantu, replied, "We focus on the user experience, which is how easy to use!"

Mark Shuttleworth went on to explain: "stabilizing and maintaining the system kernel is essential for Ubandu." At Canonical (Ubuntu parent company) we have about 25 kernel engineers to ensure that the department works well from the ARM architecture to the Xeon processor. The job of the kernel team is to make sure that Ubandu runs well on laptops, servers or the cloud. They are responsible for the most commonly used kernel in the release of the Ubuntu version. "

In response to the fact that Ubuntu is not on the list, Mark Shuttleworth said: "the kernel part is only a small part of the Ubuntu user experience. We will not take the development of the kernel as our primary goal. We stay ahead of the Unity desktop environment, and the addition of tools such as MAAS [Metal as a Service] and Juju makes Linux an ideal environment for developers and makes system administrators and end users feel the unique charm of Linux systems."

Indeed, the Linux kernel is very important, after all, there is no kernel, just like building castles in the air. But as Mark Shuttleworth points out, the contribution of Canonical to the community cannot be ignored. There is no denying that Ubuntu is making his desktop irresistible. Will there be Ubuntu TV? It's possible. The important thing is that Ubuntu is constantly pushing Linux to develop in different areas. Whether you like Ubuntu or not, you have to admit that Canonical is trying to make Linux more user-friendly.
