The independent video card refers to the existence of a separate board, which needs to be plugged into the card on the corresponding interface of the motherboard. Independent graphics card has a separate video memory, does not occupy the system m
MPEG-1: Is the first video and audio lossy compression standard developed by the MPEG organization. The video compression algorithm was defined in 1990. At the end of 1992, MPEG-1 was formally approved as an international standard. MPEG-1 is a video and audio compression format that is customized for CD-ROM media. A 70-minute CD-ROM transfer rate is approximately

former leads are staggered, which is commonly known as "golden finger". The latter leads are generally up and down. VGA socket: it is a socket with 15 Jacks and looks a bit like a capitalized "D" (to prevent reverse insertion ). Different from the Midi connector on The Sound Card, the Jack of the VGA socket is set in three rows, with 5 holes in each row. The MIDI connector has 9 holes and 2 holes, A little longer than the former, a little flat. VGA
to see the video card good or bad? The following small series focus for you to introduce these detected graphics card parameters.

"Process": the core of the production process, Unit Nano, the smaller the mo
PCI interface has the highest rate of 266mb/s,1998 years and is replaced by the AGP interface. However, there is still a new PCI interface of the graphics card, because some server boards do not provide an AGP or PCI-E interface, or the need to build a multiple-screen output, the purchase of PCI graphics card is still the most cost-effective way.

What is the dual-card technology, in fact, this is a special system with two of similar graphics cards. The goal is often to significantly improve the entire computer's image processing capabilities, in the running of 3D games can be better performance.
Advantages: Greatly improve the computer's image processing ability
Disadvantage: Due to price and performance requirements, ordinary users do not need to configure two graphics cards

following command:Sudo ln-S/usr/lib64/usr/lib32Then install envyng to complete the installation.
(3) What if the black screen of the computer is restarted after the video card is installed?Don't worry, simple task, huh, huh.Press CTRL + ALT + F1 to switch to the terminal. Let's first find the problem, log on to the terminal, and enter the command:
More/var/log/xorg.0.log | grep "(EE )"
And
, there are currently several commands that can be used to obtain hardware information. The lspic command line tool can be used to obtain the hardware information of the video card.
You can use the following command to obtain the video card information on the system:
Lspci-vnn | grep VGA-A 12
After the execution, you

Generally, if the configuration process is programmed to implement X, the system must call fork as a sub-process to run the preceding command. After the X server is successfully started, run a small graphical program and let the user choose whether the configuration is successful.
Of course, if you cannot obtain the detailed device parameters of the video
