I believe that you have read the dual-Display Method of N card on our website, and some people have doubts: Can a card be also made into dual-Screen Display in linux? The answer is yes, yes. Next let's take a look at how a is configured as a dual-Screen Display in linux.

Hardware Platform:

Video Card: ELSA V3400 (FireGL)
Power Supply: 500 W

Hard Disk: st sata 160 GB
Operating System: redhat AS3 u6

First, download the ati driver from the ati official website. Select linux X 86/FireGL/v3400 (here you can select your driver ). Download is A. run file such as: ati-driver-installer-8.29.6.run. Enter the character interface before installation. You can enter init 3 in the terminal or press Ctrl + Alt + F1 to enter the character interface. In the character interface to enter the root account to enter the atidriver folder, run sh ati-driver-installer-8.29.6.run will pop up a box asking whether to accept the Protocol, whether to access the ftp server to view the latest version, after the installation is completed, the installation will be automatically returned to the character terminal and a prompt will be displayed: after a successful installation, please run "aticonfig" indicates that after the installation is successful, run the "aticonfig" command. Enter the information shown in the prompt.

Let's not underestimate the usage of these commands:
　　
1. Single head: aticonfig -- initial -- input =/etc/X11/xorg. conf
2. Dual-screen mode (dual head): aticonfig -- initial = Dual-head -- screen-layout = above
3. Working Mode (parallel) of the first and second monitors: aticonfig -- dtop = horizontal -- overlay-on = 1
4. Set the screen resolution (1024 × 768): aticonfig -- resolut: on-0, 1024 × 768,1280 × 1024

After seeing these commands, do you have a dual screen for the card. Next, you can press CTRL + ALT + F7 to enter the graphic interface. You can see that the two screens are already dual-screen. If you want to change the other mode, you can debug it in the application-ati contral, just as simple as in the window. Hurry up!
