.........
Endsection
. Here we explain the meaning of each node.
One, input equipment--keyboard
Copy Code code as follows:
section "InputDevice"
Driver "KBD"
Identifier "Keyboard[0]"
Option "Protocol" "Standard"
Option "Xkblayout" "Us"
Option "XkbModel" "pc104"
Option "Xkbrules" "XFree86"
Endsection
Second, input equipment--mouse
Copy Code code as follows:
section "InputDevice"
Driver "Mouse"
Identifier "Mouse[1]"
Option "Buttons" "5"
Option "Device" "/dev/input/mice"
Option "Name" "Imps/2 Generic Wheel Mouse"
Option "Protocol" "EXPLORERPS/2"
Option "Vendor" "SYSP"
Option "Zaxismapping" "4 5"
Endsection
Third, monitor
Copy Code code as follows:
section "Monitor"
Displaysize 305 230
Horizsync 29-35
Identifier "Monitor[0]"
ModelName "800x600@56hz"
VendorName "--> VESA"
Vertrefresh 50-60
Usemodes "Modes[0]"
Endsection
among them,
Identifier: The unique name of the display. After these names, a number is added, and the first display is represented by 0 (Monitor[0]).
VendorName: Display manufacturer name.
ModelName: Display type name.
Horizsync: The horizontal refresh frequency range that is compatible with the monitor, in khz. This setting value also indicates whether a specific Modeline value is used in this monitor.
Four, graphics card
Copy Code code as follows:
section "Device"
Boardname "VMWARE0405"
Busid "0:15:0"
Driver "VMware"
Identifier "Device[0]"
Screen 0
VendorName "VMWare Inc"
Endsection
Five, screen
A monitor and a video card form a screen, described with section "screen", such as:
Copy Code code as follows:
Section ' Screen '
Defaultdepth 16
Subsection "Display"
Depth 15
Modes "800x600" "768x576" "640x480"
Endsubsection
Subsection "Display"
Depth 16
Modes "800x600" "768x576" "640x480"
Endsubsection
Subsection "Display"
Depth 24
Modes "800x600" "768x576" "640x480"
Endsubsection
Subsection "Display"
Depth 8
Modes "800x600" "768x576" "640x480"
Endsubsection
Device "Device[0]"
Identifier "Screen[0]"
Monitor "Monitor[0]"
Endsection
which
Identifier: Defines a "screen" name to be referenced in the "Serverlayout" section.
Device: Specifies the name in the "Device" section.
Monitor: Specifies the name in the "Monitor" section.
Defaultdepth: The default color depth (color Depth) number of digits.
Modes "800x600" "768x576" "640x480" means that the system will default to the resolution of 800x600 to fit, if the match fails, then select 768x576 resolution to continue.
VI. Modes
Copy Code code as follows:
section "Modes"
Identifier "Modes[0]"
Modeline "800x600" 35.55 800 832 912 1024 600 601 604 620
Modeline "768x576" 33.74 768 792 872 976 576 577 580 596
Modeline "640x480" 23.86 640 656 720 800 480 481 484 497
Endsection
Corresponds to the Modes in the screen section.
Seven, Serverlayout
Copy Code code as follows:
section "Serverlayout"
Identifier "Layout[all]"
InputDevice "keyboard[0]" "Corekeyboard"
InputDevice "mouse[1]" "Corepointer"
Option "Clone" "Off"
Option "Xinerama" "Off"
Screen "screen[0]"
Endsection
The Serverlayout section is primarily used to build the appearance of X server startup, where:
Identifier: The unique name of this serverlayout section.
Screen: Name specified in ' Screen ' section
InputDevice: The "inputdevice" section name in X server. There are usually only two lines set here, namely Mouse[0] and Keyboard[0], the first mouse and keyboard in the system, and most of the other devices can be ignored.
