The dual screen of UbuntuLinux is not as simple as Windows. In the final analysis, it is still a Linux permission problem. Because of its strict permissions, it is difficult to set up, which has advantages and disadvantages. Today, the company's computer is finally mistakenly displayed on the dual screen, a 1680X1050 wide screen main display, and a 1280X1024 secondary display, used to test the compatibility of different resolutions on the web page.

Ubuntu Linux dual-screen is not as simple as Windows. In the final analysis, it is still caused by Linux's own permissions. Because of its strict permissions, it is difficult to set up, which has advantages and disadvantages. Today, the company's computer is finally mistakenly displayed on the dual screen, a 1680X1050 wide screen main display, and a 1280X1024 secondary display, used to test the compatibility of different resolutions on the web page.

Installation Steps: There is a hardware driver under the "system"> "System Management" menu of Ubuntu. After opening the driver, let Ubuntu search for it. After Ubuntu finds the video card, it will automatically download and install the driver. After the installation is complete, run the sudo nvidia-settings command to start the settings box. Do not start from "system"> "System Management"> "nvidia x Server Settings" because the configuration file cannot be saved without the root permission after startup.

Find the secondary Monitor (you do not need to set the primary display) and enable configure in three modes:

Disable -- Disable

Effecate X screen-independent screen display, that is, the two screens do not interfere with each other

TwinView-Dual-Screen mode. You can select overlapping display or clone display. Overlapping display means that the two displays are combined into a large display. Clone means that the two displays are identical.

Generally, you can enable it directly by setting it to TwinView, but this mode is often not the desired one. Because you want two screens to interact with each other, You need to select the effecate X screen mode.

However, if no permission is set, an error is returned.

After searching for half a day, I found a solution for foreigners:

How I fixed it:

1) open a terminal

2) sudo mv-I/etc/X11/xorg. conf/etc/X11/xorg. conf. backup

2) sudo touch/etc/X11/xorg. conf

3) sudo nvidia-settings

4) hit "save configuration"

With the empty xorg. conf, nvidia-settings shocould properly save the file.
