Ubuntu7.10 extends multimedia applications in Linux

Article Title: Ubuntu7.10 extends multimedia applications in Linux. Linux is a technology channel of the IT lab in China. There are some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems. No Linux system can compete with Windows hardware compatibility. However, users will be surprised to find that Linux has extensive support for graphic devices.
　
Early Linux desktops were a rough system and had more in common with technical workstations than modern consumer PCs. However, due to the joint efforts of Linux vendors, video card manufacturers, and open-source programmers, the current Linux system can provide GUI (graphic user interface) animation functions, which is comparable to the latest products of Apple and Microsoft.
　
Ubuntu (a Linux System) supports many graphical functions by default during the installation process, but in some cases, additional configuration may still be required.
　
　　 Video Card Acceleration
　
The competition in the graphics equipment market is fierce, and video card manufacturers are reluctant to publish too much information about their internal work methods. It is for this reason that it is very difficult to develop open-source graphics drivers that support modern graphics functions such as 3-D acceleration.
　
Fortunately, ATI and nVidia provide customized Linux Device Drivers for their products. These drivers are patented, which means Ubuntu will not install them by default. If your computer uses the hardware products of these suppliers, you can enable the "Accelerator drive program" function from the following control panel: System à adminià à Restricted Drivers Manager.
　
Font Decoration
　
If you install Ubuntu on a laptop or a desktop with LCD monitors, you can enable the "Smooth Processing of subpixel fonts" function to improve the font definition on the screen, it is equivalent to Microsoft's "ClearType" technology. You can select from the "Fonts" tab on the "System-> Preferences --> Appearance" control panel. In the "Details" menu, try different options to find your favorite settings.
　
If you want to further enjoy the experience of Windows fonts, you can use Synaptic management tools to install the "msttcorefonts" package, and then Linux applications can use familiar Microsoft fonts, for example, Arial, Courier New, and Times New Roman.
　
　　 Configure desktop Effect
　
Compiz Fusion, the most talked about development of Linux Desktop recently, is a new GUI management software that provides a variety of dazzling animation effects and other graphic effects for common GUI functions. The most striking is "desktop cube", which allows users to switch between multiple desktop workspaces by rotating a three-dimensional selection box with the mouse.
　
Ubuntu 7.10 is the first version with the default Compiz Fusion effect. The "Visual Effects" tab on the control panel "System à Preferences à Appearance" allows you to choose to make your computer desktop stable or appealing. To start an additional menu item for customizing various effects, you can use Synaptic to install a software package called "compizconfig-settings-manager. On the other hand, if the user's GUI function is poor, it is best to disable the Compiz function.
　
　 Complex status quo of Multimedia Technology
　
Due to a large number of patent rights related to auditory visual technology, multimedia support technology often has many problems for open-source software. When Ubuntu is released, multimedia formats restricted by patent rights are not installed by default. However, Ubuntu programmers have added some functions to the system, allows users to install these multimedia digital signal codecs (codec) as easily as possible as needed ).
　
For example, when a user tries to play an MP3 music or a Windows AVI (multimedia file format) file for the first time, the Totem Movie player displays a dialog box, ask the user if they want to find suitable software for playing. You must only install each multimedia digital signal decoder once. Similarly, the Firefox Web browser in Ubuntu 7.10 contains a new feature that automatically finds suitable plug-ins for new file content types, including Java applications and Adobe animations.
　
It is worth mentioning that the multimedia support technology of Ubuntu has not been extended to DRM (Digital Rights Management) to encrypt media files. So far, no audio or video protection system has opened ports for Linux. This means that MP3 Music copied from a CD can be played well, but for example, Music downloaded from iTunes Music Store cannot be played.
