Introduction to the Xorg. conf file in Linux

Introduction to the Xorg. conf file in Linux

 

First look at a complete Xorg. conf file, as shown below:

Through the above Code, we will find that the Xorg. conf file is composed

Section "XXXX"

.........

Endsection

The following describes the meaning of each node.

1. Enter the device-keyboard

Section "inputdevice" <br/> driver "KBD" <br/> identifier "keyboard [0]" <br/> Option "protocol" "standard" <br/> Option" xkblayout "" us "<br/> Option" xkbmodel "" PC104 "<br/> Option" xkbrules "" xfree86 "<br/> endsection <br/> 

2. Enter the device-Mouse

Section "inputdevice" <br/> driver "Mouse" <br/> identifier "mouse [1]" <br/> Option "buttons" "5" <br/> Option" device ""/dev/input/mice "<br/> Option" name "" imps/2 generic wheel mouse "<br/> Option" protocol "" assumerps/2 "< br/> Option "vendor" "sysp" <br/> Option "zaxismapping" "4 5" <br/> endsection <br/> 

Iii. Display

Section "Monitor" <br/> displaysize 305 230 <br/> horizsync 29-35 <br/> identifier "monitor [0]" <br/> modelname "800x600 @ 56Hz "<br/> vendorname" --> VESA "<br/> vertrefresh 50-60 <br/> usemodes" modes [0] "<br/> endsection <br/> 

Where,

 

Identifier: Unique name of the monitor. Add a number after these names, and the first display represents 0 (monitor [0]).

Vendorname: name of the display manufacturer.

Modelname: name of the display type.

Horizsync: the horizontal refresh frequency range compatible with the display, in kHz. This setting value also specifies whether a specific modeline value is used in this display.

Iv. graphics card

Section "device" <br/> boardname "vmware0405" <br/> busid "" <br/> driver "VMware" <br/> identifier "device [0]" <br/> screen 0 <br/> vendorname "VMware Inc" <br/> endsection <br/> 

5. Screen

A display and a video card form a screen, which is described by section "screen", such:

Section "screen" <br/> defaultdepth 16 <br/> subsection "display" <br/> depth 15 <br/> Modes "800x600" "768x576 "" 640x480 "<br/> endsubsection <br/> subsection" display "<br/> depth 16 <br/> Modes" 800x600 "" 768x576 "" 640x480 "<br/> endsubsection <br/> subsection" display "<br/> depth 24 <br/> Modes" 800x600 "" 768x576 "" 640x480 "<br/> endsubsection <br/> subsection" display "<br/> depth 8 <br/> Modes" 800x600 "" 768x576 "" 640x480 "<br/> endsubsection <br/> device" device [0] "<br/> identifier" screen [0] "<br/> monitor" monitor [0] "< br/> endsection <br/> 

 

Where,

 

Identifier: defines a "screen" name for reference in the "serverlayout" section.

Device: specify the name in the "device" section.

Monitor: Specifies the name in the "Monitor" section.

Defaultdepth: the default number of digits in color depth.

Modes "800x600" "768x576" "640x480" indicates that the system will first adapt to the X resolution by default. If the adaptation fails, select the 768x576 resolution to continue.

6. Modes

Section "Modes" <br/> identifier "modes [0]" <br/> modeline "800x600" 35.55 800 832 912 1024 600 <br/> modeline" 768x576 "33.74 768 792 872 976 576 577 580 <br/> modeline" 596x640 "480 23.86 640 656 720 800 480 <br/> endsection <br/> 

Corresponds to modes in the screen section.

7. serverlayout

Section "serverlayout" <br/> identifier "layout [all]" <br/> inputdevice "keyboard [0]" "corekeyboard" <br/> inputdevice "mouse [1]" "corepointer" <br/> Option "clone" "off" <br/> Option "xinerama" "off" <br/> screen "screen [0]" <br/> endsection <br/> 

The "serverlayout" section is mainly used to create the appearance of X server at startup, where:

 

Identifier: the unique name of this serverlayout section.

Screen: Name specified by "screen" section

Inputdevice: name of the "inputdevice" section in X server. Generally, there are only two rows, namely, mouse [0] and keyboard [0], that is, the first mouse and keyboard in the system, while most other devices can ignore them.
