OpenSUSE 12.1 installation and basic settings

Why choose openSUSE? I have been using Ubuntu for almost a year and have basically gotten used to the unity style. However, during use, I can always touch various bugs in it. I am very upset. I didn't know what to do a few days ago, broken the desktop again ...... After a long tangle, this time the brother really broke out, easy to master! But now it seems that ubuntu is really beautiful and user-friendly. After a long time, it is easy to form a mindset. When you are young, you should try more! I have always been fond of the German operating system and can finally try it! But it will still cheer for ubuntu silently ......
 
I. Desktop Selection
 
Gnome2 is a classic desktop, but the wheel of history will not stay here. Just like the popularity of touch screens, no one can block the historical trend. Modern desktops are also moving toward beautiful, intelligent, humane, convenient, and so on. I always thought that as a young man, we should promote the society to develop in such a harmonious, friendly, and healthy direction and be brave enough to accept new things, rather than just like a stubborn old lady at the age of 70 or 80 ...... Well, it's a bit far away. Let's talk about the installation experience. The first installation was the KDE Desktop of openSuse, which is also the default desktop environment. However, after the installation, I probably experienced it and found that I was disgusted with it, and the more you see it, the less you get used to it! Although many people say they are comfortable and recommended by the official team, this is not what I want! But what do I want? Hate KDE, dislike xfce, dislike unity, or gnome3 ...... May like MacOS? Do you like the character interface? I think linux users will always struggle on this because there are too many choices. I think I 've got the gnome virus. After thinking twice, I decided to reinstall it again. opensuse has the gnome Desktop option. After I installed it, I found it was gnome3, a little disappointing, but I decided to change and change my habits. After all, the new gnome has many advantages. change !.
 
 
 
2. gnome3 initial experience
 
In addition to special effects, it is strange to have a few details. One is that the window only has the close button, which is not minimized or maximized, and the other is that there is no right-click on the desktop, which makes people feel that the mouse is broken, by default, the system does not allow file operations on the desktop, so the desktop is very clean and there is nothing. These can be modified using the gnonme-tweak-tool (after modification, enter the r command to restart the gnome Desktop ). I modified it at the beginning, but then I changed it back, because it didn't make much sense. Gnome3 seems to be passing another operation method to people to keep all windows open (not minimized), and then quickly switch the window through the alt + tab shortcut. Of course, this is more dependent on virtual desktops (I have never used it before). In fact, gnome3 also provides enough virtual desktops (more than four ), you can use ctrl + alt + up/down to switch the desktop. There is also a super key win that allows you to preview common programs, opened programs, and opened virtual desktops. Unfortunately, you cannot add components on the Panel. It is troublesome to start the program. After you press win, click the program icon (no faster method has been found ). There is also a shortcut key, alt + f2, input the program name, very useful, but it is still slow, slowly explore it, use the shortcut key is very efficient!
 
 
 
3. Set the update source
 
First of all, popularize the concept of 'source'. I understand that it is a Web site, similar to a software warehouse, through which software can be installed and updated, so linux is very dependent on the network. Software can be installed only when a specific source is added. There are many sources, various sources, and some are fast and slow, so you must set them carefully.
 
Note the following when adding a software source:
1. Unofficial sources may contain unstable software packages in the test.
2. Different software sources are not necessarily compatible
3. An unofficial software source is not always stable and trustworthy
4. Too many software sources will reduce the speed of the Software Package Manager.
 
Add method:
 
1. graphical: Select yast> software manager> configuration> repositories
 
By default, the system provides official sources. Click add to view various options, such as adding a DVD and adding a local ISO image file, to add a specific website (if you know the website), Community Repositories is the most convenient for beginners. It is useful and comprehensive. You can choose to add it. For details, refer to the following.
 
2. Command method (Administrator)

Opensuse source Overview:
 
The source of openSUSE is very large and hierarchical. It consists of three parts: basic source + third-party source + BuildService source. The OSS, NON-OSS, and Update Packman sources are mandatory. The source configuration files of other sources are in the/etc/zypp/repo. d/directory as needed. Back up the files before performing the operation.
 
1. Basic Source
Including common OSS source (Open source Software), NON-OSS (non open source software), UPDATE (update); not commonly used source, debug, UPDATE debug. This group is selected as the main update source, which is fast in the campus network and Sohu in China. The source speed of 163 is very fast and will not be listed here.
Http://ftp.sjtu.edu.cn/opensuse/update/12.1/
Http://ftp.sjtu.edu.cn/opensuse/distribution/12.1/repo/non-oss/
Http://ftp.sjtu.edu.cn/opensuse/distribution/12.1/repo/oss/
 
2. Third-party source
It is a good supplement to openSUSE, where Packman is essential and many desktop applications are in it. Others include Java-related, Google, Mono, MadWifi multimedia software, and Decoder source addresses. There are a lot of, here there are two casually listed:
Http://ftp.twaren.net/Linux/Packman/suse/12.1/
Http://packman.inode.at/suse/12.1/
Nvidia driver Compiz
Ftp://download.nvidia.com/opensuse/12.1/
 
Wireless Network Adapter:
Http://download.opensuse.org/repositories/driver:/wireless/openSUSE_12.1/
 
CodeBlocks and other IDE:
 
Http://download.opensuse.org/repositories/devel:/tools:/ide/openSUSE_Factory/
 
3. BuildService Source
This is a special feature and pride of openSUSE. It is free and open, allowing communities and individuals to easily create sources for openSUSE, or even other Linux distributions. BuildService provides a combination of Apache server, Banshee player, Compiz effect, Educaiton education, Kernel, Java, KDE, Gnome, Mozilla, M17N, Moblin, and openoffice, in addition, each project is divided into stable versions, factory test versions, and unstalbe unstable versions. When you add three sources: stable, factory, and unstable, execute "zypper dup" to upgrade them to unstable. Then you delete the unstable source configuration file, execute "zypper dup" to downgrade to the factory. That is, each execution of "zypper dup" will update the latest status of the valid configuration file under/etc/zypp/repo. d. Because the Build Serive is too large, it is recommended to search in the http://software.opensuse.org/search and then use a one-click installation to add, of course, the one-click installation source will also be preserved for upgrade. You can find these sources in the Community Repositories mentioned above and will not list them.
 
4. Set your DVD iso as the local source
 
In this way, you can add software when there is no network. When I first installed opensuse, I didn't bring gcc and make. In this way, I can compile the online software.
 
5. Priority)
 
You can set the priority of each source. The default value is 99. The smaller the number is, the higher the priority is.
 
 
 
4. Configure Chinese Input
 
We recommend scim. After using scim, it will feel very intelligent, better than ibus and fcitx.
 
Sudo zypper install scim-pinyin scim-tables
Choose System Settings-> Yast-> Language-> Secondary versions, and select Simplified chinese. After the restart, you can use it.
 
 
 
V. Multimedia settings
 
Flash is still essential for desktops.
 
Sudo zypper install flash-player
For other commonly used Software, you can either install it using a command similar to the above, or search for the Software package directly in System Settings-> Yast-> Software Management, and then install it with apply.
 
 
 
Vi. Available Resources
 
I found that there are not many opensuse users in China, but the official documentation is complete! Go to wiki, maillist, BuildService, forum, Packman, and other places.
 
List several websites for Searching Software: (you can search and download and install them directly)
