How to adjust the resolution and screen refresh rate of Ubuntu system?

After installing the Ubuntu system, the system default screen resolution is too low. The 1280*1024 display shows a resolution of only 800*600. In most cases, after the system is reinstalled, it is necessary to re-adjust the screen resolution to fit the display. So how do you adjust the resolution and screen refresh rate of the Ubuntu system?

1. command line: cvt & lt; you need a resolution of space & gt; & lt; refresh rate & gt;

I want to set as 1280 * 1024, refresh 75, and then input Cvt 1280 1024 75 Enter, the Modeline information is what we need, such as:

root@mypc:~# cvt 1280 1024 75

# 1280x1024 74.90 Hz (CVT 1.31M4) Hsync: 80.30 kHz; pclk: 138.75 MHz

Modeline “1280x1024_75.00& rdquo; 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync

Copy a red line.

2. Command line: sudo gedit /etc/X11/xorg.conf Open the configuration file. It doesn't matter if there is no such file.

Add the following content to this file:

Section “Monitor”

Identifier “Configured Monitor 

Modeline “1280x1024_75.00” 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync

Option “PreferredMode” “1280x1024_75.00 ”

EndSection

Section “Screen”

Identifier “Default Screen”

Monitor “Configured Monitor”

Device “Configured Video Device”

EndSection

Section &ldquo ;Device”

Identifier “Configured Video Device”

EndSection

The above red is the place to be modified according to different configurations. In fact, the important thing is the cvt command.

Ubuntu system to adjust the screen resolution and refresh rate is achieved through the command line, in general, Ubuntu resolution is used cvt command, if there is no xorg.conf, you can use the second Order.
