Ubuntu linux introduction ubuntu linux, is a debian-based linux operating system in the desktop application, it is one of many in a linux system easy to use release is one of the most popular linux distributions (Note: The server-side functionality is not weak). two. ubuntu What are the advantages linux and other popular linux system, such as fedora, opensuse, red and other than, ubuntu linux has the following advantages, features and these features are directly determined it as a "door-class mainstream, consumer-grade linux system" status : 1 free, always free, even if the server version, no additional charge. 2 interface is easier to operate, easy to use, close to the user habits. In the ease of use graphical interface operation done greatly improved, making the low-level maximum from the user "command line" operation (a powerful command-line work still exists) 3. everywhere in the world with ubuntu linux system "update server" (called "source"), the server in addition to providing The latest, completely free system update patches, as well as the latest stable version of the super large variety of free software for users to download and install ready to use, such as: Netease, have your ubuntu system update server 4. super perfect Chinese forum support, and solve any problems encountered can always ask, always refer to previous solutions, although other versions have their own forum, but can not match the size and number of various ubuntu forums. Oh 5 system itself three methods of installation for the user to select 6. the vast majority of mainstream support for the current hardware, try to reduce the hardware compatibility problems resulted in the installation, use to happen. 7 users with the system continued to increase significantly The best liquid foundation you can always find different ways from the same hobby with their friends, in addition to the official Chinese Forum in ubuntu question outside the exchange, qq group and other channels can also find a large number of ubuntu system user groups, help each other, share, is the fine tradition of ubuntu people 8. super friendly "apt package management system", the maximum package to help users automatically resolve "dependency" in apt before the advent of software is most troubled by relying on linux the user's problem. three. ubuntu linux the "branch" ubuntu linux, this release, there are several sub-versions of the following as basic knowledge, we first know on the line. They are: first, to add point-based knowledge, in many linux systems have a "graphics window server" this thing. graphics window server, this means that we can see on the desktop such as icons, windows style, theme, sounds, and even comes with a variety of software systems, They form a "set of dry . linux world, there are many, many graphical window manager, there are common: gnome, kde and xfce, these three. ubuntu linux, based on these three different styles of window managers, the majority of fans were customized for the three different versions of ubuntu linux branch. 1. Kubuntu linux: use kde-desktop graphical window manager version kde, is a very nice desktop window manager, with many of its own (kde) "proprietary" software. kde desktop not only for kubuntu linux, widespread in some other version of linux, is also widely used. Such as; fedora, red flag. And the general version of ubuntu (gnome based window manager), compared, kde, many details of the operation are extraordinary humanity. The advantage for the novice and sometimes it touches into a "burden." As the set has done too detailed, sometimes confusing, do not know what you want to set, specifically where. Therefore, this version is not recommended to use just a novice user. Figure it: 2.ubuntu linux: use gnome-desktop graphical window manager version is recommended for newbies this is the official version of the default version. Is the largest version of the current user. gnome-desktop also comes with a lot of software for everyone to use. The simplest view of operability and stability, suggest that the majority novice to use this version. 3.xubuntu linux: use xfce window manager desktop graphics version of this is a "lightweight" ubuntu, system resources is relatively small, it fits a lot of pure "antique" computer. For example: p4, 1.0,256 memory. . . . Oh, it is estimated would have to use it. Use this window manager operations, compared to the above two, the operation of some relatively primitive, not very used to get started early. Therefore, only recommended for people new things to use. 4. Ubuntu linux server: This is the server version, which itself does not rely on any window manager work. That is "only the most basic terminal, kernel," installation finished on dark - pure state in the command line operation. Of course, this is certainly not suitable for a novice user. Three. Install ubuntu linux configuration I need to say in front of a, ubuntu for the hardware (mainly cpu and memory) requirements low. According to the official statement, the lowest minimum configuration of ubuntu installation running: p4 1.0g or more of the cpu, 512m memory, hard disk space 5g. Of course, this is the minimum configuration, it is estimated that the configuration of the computer is now rare, right? 1 for the current cpu, divided into 32-bit and 64-bit. So ubuntu linux is also divided into 32-bit and 64-bit version. However, many rookie new people, we do not consider: my cpu is what A, which corresponds to the installed version of A. ~ I tell you, if you are not holding the play-see attitude on the installation of the default 32-bit version of the official on the line. The reason is simple, although 64-bit systems can use the normal installation, but very little software support. Many companies let alone in linux, that is, the windows are not willing to develop the corresponding 64-bit software. Such as Tencent qq, in the linux version, the official on the only 32-bit systems to use. We do not want to install on ubuntu, can not even qq, right? 2 on computer hardware: network card, sound card, video card for ubuntu linux, most of the network card and sound card market, is no need to install additional drivers. This we can be assured. If your computer is 2,3 years ago, that 95% have to worry about drive problems. Graphics card. In many linux systems, graphics do not like the windows system, as have to install drivers to use. linux system has built-in "compatible" graphics driver. The driver will be able to guarantee the basic operation of the computer. In ubuntu linux, the system installed, does not specifically install the graphics driver, can still use the system properly. If you hope to see on "brilliant 3d desktop effects, such as cube rotation, transparency, snow or something," play some 3d games, this time it is necessary to separately install the official (manufacturers) provide for linux graphics drivers. Four. Ubuntu linux (linux is also applicable to other systems, such as fedora, centos, redhat) the need to install the driver? 1 for the current most popular linux distribution systems, are completely without having to install the motherboard chipset drivers. Are built. 2 In addition to the basic motherboard chipset drivers, now most of the linux system, have built most of the common, popular: sound card, network card drivers. System installed, a simple network configuration, you can try, if there is a shadow of the net sound, it is naturally "integrated in the system with the inside, comes with the drive." Therefore do not need to have control of. 3 is the rest of the graphics card. linux and windows is not the same, even if you do not "install" video driver, your linux system can still be used normally. Because, it is also "built" a lot of large graphics card driver. But, the built-in graphics driver, not the real (video) official driver, because the official driver is not open source and can not be modified. Thus, linux company built a "do their own" graphics driver, but not in the system which will integrate good official "closed source driver." The driver, usually only the most basic display, that is, to ensure your system's normal display operation. 4 just said, because the official graphics drivers, linux company can not "modify", naturally we can guarantee the "security." Thus, in the linux system inside (System - system management - hard drive) which will set out some of the hardware drivers, such as wireless LAN and graphics. Here set out the drive, is the system can automatically help you install, the real official drivers. But - the driver can work, will not be any problems, what the unknown bug, linux, Inc. assumes no responsibility. Therefore, whether to use the official drivers, you need to decide manually to "activate." For ubuntu, nature is the same, you go and see "System - system administration - hardware drivers," which is not have your graphics card driver. (Activated) to install the graphics driver, the most common use is: Open the 3d desktop effects, it is estimated that many people are reading ubuntu 3d special effects show, decided to embrace it into ubuntu? Hey, this must be "activated" the official driver a ~ activated, you can set through the installation of special effects software to configure the specific effects, such as the 3d cube, transparent menus, desktop rain, and so on. Specific configuration, see it here: http://forum.ubuntu.org.cn/viewtopic.php?f=120&t=13 floor, there is a common method of setting effects. V. Before installing ubuntu linux preparation 1. Preparing network connections have to admit, is for ubuntu linux. Percent of the Internet is important. Therefore, you must first be clear, what is your means of access is adsl? Router? Campus? Switch? Something or other. And, to prepare in advance the appropriate "in linux" configuration access method. This certainly must be prepared in advance! Liquid foundation router to ignore the user, the router in ubuntu, the system can automatically detect configuration access to the Internet. 2 is divided up your disk space you are ready to think about how many points to ubuntu linux hard drive capacity. I said earlier, the government provides at least the minimum to 5g. Of course, the bigger the better. If you really do not drive off, I personally recommend and give ubuntu :10-15g. 3 in the windows system, verify that the card model where you have to do this, although I said, ubuntu includes a n network card drivers more than the common market. But not 100%. Therefore, to advance under the windows of your network card to view specific models, such as: realtek 8139, via rine, like this. If your computer is relatively new, such as this year has just bought. It is the best model according to the card, go to the following Web site to view, ubuntu if your card comes with a driver. https://wiki.ubuntu.com/hardwaresupportcomponentsw irednetworkcards This site lists the ubuntu comes with many companies the specific NIC model, showing that they are able to automatically inside ubuntu, normal work. Unfortunately, in English, if you really do not understand, find someone to help it to 4. Learning about ubuntu linux system installed "Partition" operation regardless of ubuntu, or other linux version, this all must learn, and I has been specifically written tutorials for everyone, where we look directly on the line: http://nkevin.blog.163.com/blog/static/ / six. ubuntu linux version of Option 1. version of choice (I use Which version?) just said, ubuntu linux, there are many segments of the following versions. For starters, I am the main push this version: ubuntu linux 9.04 desktop i386 (32 bit), because this version is the official release version of the default, but also gives users the most, most easy to use interface. What exactly makes a good foundation for entry to use. Direct Download, right - Thunder download: http://releases.ubuntu.com/jaunty/ubuntu-9.04-desk top-i386.iso2. Ubuntu linux cd and dvd difference between ubuntu cd version available (700m) and dvd (4.2 g) of the two systems installation files. I have given above is the cd version of the download address, of course, the recommended version, as well as dvd version. The difference between cd and dvd: dvd version which includes the countries of the language pack, so the system is installed, that is, all Chinese, and it has Chinese input method. The cd version brought the language pack is not complete, most of them after the installation or English, to the Internet to download the remaining Chinese language pack and Chinese input method. In addition, dvd cd more than the number of "all kinds of software to run" the need "library files, like dll file under windows is almost fact this is not obvious, do not feel the course, so the key is the language packs and input method of difference. we can according to their own situation to determine the network, is to download cd or dvd. pay attention! cd version there are three installation (later), but the dvd version, as most good or burn a CD to install. To novice to become familiar with "real" configuration of ubuntu, I hope to see that we can try to choose the cd. Although the cd Zhuangwan to Internet download language packages and input methods, but I think this configuration, For novices to adapt to ubuntu, of great help. seven. ubuntu linux installation method ubuntu linux (cd version) offers three different installation methods for your choice, and I were under a simple summary. good use of what we want to advance way to install 3 different ways, I wrote a blog tutorial, we can directly refer to, and then learn how to install concrete. 1. wubi install wubi, ubuntu is a system-specific software, the software is running on windows system inside. which is in the windows system, to adopt a "virtual analog" way to install ubuntu. this method to install the ubuntu system, in fact, as the windows of a "software." So many of the windows can not be separated yet novice in this way. ubuntu latest version is 9.04, which of course comes wubi.exe, the software (cd version there, dvd does not!), but there is a problem. 9.04 under wubi.exe, as own shortcomings, in the part of windows system (xp) does not run smoothly, so will not be further installed, although now there are ways to make up, but too much trouble for the novice or so, which depends on everyone's luck If you decide to install this way ubuntu, do not worry first download the installation file (iso file). wubi.exe below can be downloaded first, see if you can run if you can, then a separate download iso file. ubuntu 9.04 wubi.exe Download: http://releases.ubuntu.com/jaunty/wubi.exe In addition, there is a problem, perhaps some of the installer useful way to use wubi to install, in fact, the installation process it will Automatic Internet download iso file without the need for you to download a separate, but!!! I strongly oppose us do so because, wubi.exe will be based on your cpu, to each their own, or download the 32-bit 64-bit and many people are do not know this, sleepwalk download and install a 64-bit version, the system is installed, only to find the official (32) of the qq can not be installed! therefore, strongly urge you, yourself manually download iso file, do not let wubi to download! ubuntu linux with wubi installation tutorial (though tutorial is to install 8.04, but the contents of the steps in exactly the same way, Zhaomaohuahu it ~): http://nkevin.blog.163.com/blog/static/ / ubuntu linux 9.04 version wubi.exe not run solution: http://nkevin.blog.163.com/blog/static/ / 2. install a hard drive installed in this way for the novice, the more complex than the above method. need to be installed inside the windows system : "grub 4 dos" this software, and simple configuration, so here I do not recommend you use this method unless forced to, you can not use the above wubi, and it really did not burn the disc condition, consider this approach it, the tutorial is as follows: windows xp hard drive to install under ubuntu linux 9.04: http://nkevin.blog.163.com/blog/static/ / 3. burn a disc to install this is my most recommended, because this installation, is the real use of the real linux system. wubi after all, is a virtual, can not be regarded as "pure" and if you burn a disc conditions, to install it on a burn. This installation, the only "drawback" is in the installation process will involve the linux "disk partition" operation, therefore, need to advance individual learning linux partition operation method tutorials here, need to look at, is actually very simple: http:/ / nkevin.blog.163.com/blog/static / / ubuntu linux 9.04 cd version of the installation, configuration, full tutorial http://nkevin.blog.163.com/blog/static/ / three different installation is recommended in order : CD-ROM installation - wubi installation - hard drive installation. we all consider the right. eight. dual problem of a system referred to above three kinds of installation, according to the current online tutorial, can be automated, thorough, well build dual system (xp, vista). we do not deliberately concerns. windows 7 should be able to, but I have no chance to experiment, so not 100% guaranteed 2. three methods of installation, the installation can be directly under ubuntu access to the original windows partition and this we can be assured of the files on it, naturally, free to operate 3. with wubi installed in ubuntu, you can not access the "install ubuntu partition" inside the file, such as I the windows http://www.xxsxyy.com, use wubi to install ubuntu to f disk, then you have ubuntu, you should not see the contents of f disk. 4. windows can be used in the software under ubuntu ubuntu, there is a software called "wine", with this software, you can "simulate" the software to run part of the small windows, such as the cool dog pull, qq pull, pull TTPlayer, but it is not a panacea, although there are master online , you can use it to successfully run a large online games, such as "Perfect World." but looks like a very very very complicated. Oh as a ubuntu user, I suggest that you try not to use wine to run windows software to install, because I want to Since we decided to learn how to use linux, you should do: use its software to prepare. linux under the super and more software is also, almost able to meet everyone's request. nine. ubuntu linux Download the official me All address, you need to download it according to their own, including cd and dvd, 32 bit and 64-bit, as well as ubuntu's "branch" version. i386 on behalf of 32-bit system, I recommend you use most, even if you know the cpu is 64 bit! main push version: ubuntu linux 9.04 desktop i386 (32 bit), direct download, right - Thunder download: http://releases.ubuntu.com/jaunty/ubuntu-9.04-desk top-i386.iso other versions: ubuntu linux 9.04 64 位 cd: http://releases.ubuntu.com/jaunty/ubuntu-9.04-desk top-amd64.isokubuntu linux 9.04 32 位 cd: http://releases.ubuntu .com/kubuntu/jaunty/kubuntu- 9.04-desktop-i386.isokubuntu linux 9.04 64 位 cd: http://releases.ubuntu.com/kubuntu/jaunty/kubuntu- 9.04-desktop-amd64.isoubuntu linux 9.04 32 位 dvd : http://cdimage.ubuntu.com/dvd/current/jaunty-dvd-i 386.isoubuntu linux 9.04 64 位 dvd: http://cdimage.ubuntu.com/dvd/current/jaunty-dvd-a md64. isoubuntu 8.10 i386 cd direct download, right - Thunder download: http://cn.releases.ubuntu.com/8.10/ubuntu-8.10-des ktop-i386.isoubuntu 8.10 i386 dvd direct download, right - Thunder download : http://nl.archive.ubuntu.com/ubuntu-cdimages/8.10/ release/ubuntu-8.10-dvd-i386.iso If you need more versions of the download, please refer to this page: cd version of the download page: http://releases.ubuntu.com/dvd version of the download page: http://cdimage.ubuntu.com/dvd/current/ Oh ~ Finally, you are welcome to join ubuntu linux world!
