 133: Section "Extensions"
 134: EndSection

通过上述代码会发现xorg.conf文件由

Section "xxxx"

.........

EndSection

对组成.下面我们主要解释一下每个节点的含义。

 

一、输入设备--键盘 

   1: Section "InputDevice"
   2:   Driver       "kbd"
   3:   Identifier   "Keyboard[0]"
   4:   Option       "Protocol" "Standard"
   5:   Option       "XkbLayout" "us"
   6:   Option       "XkbModel" "pc104"
   7:   Option       "XkbRules" "xfree86"
   8: EndSection
 

二、输入设备--鼠标

   1: Section "InputDevice"
   2:   Driver       "mouse"
   3:   Identifier   "Mouse[1]"
   4:   Option       "Buttons" "5"
   5:   Option       "Device" "/dev/input/mice"
   6:   Option       "Name" "ImPS/2 Generic Wheel Mouse"
   7:   Option       "Protocol" "explorerps/2"
   8:   Option       "Vendor" "Sysp"
   9:   Option       "ZAxisMapping" "4 5"
  10: EndSection
 
 

三、显示器

   1: Section "Monitor"
   2:   DisplaySize  305 230
   3:   HorizSync    29-35
   4:   Identifier   "Monitor[0]"
   5:   ModelName    "800X600@56HZ"
   6:   VendorName   "--> VESA"
   7:   VertRefresh  50-60
   8:   UseModes     "Modes[0]"
   9: EndSection
 

其中，

Identifier：显示器的惟一名称。在这些名称后面都会加上一个数字，而第一个显示器的代表数字为0（Monitor[0]）。

VendorName：显示器制造商名称。

ModelName：显示器类型名称。

HorizSync：与显示器兼容的水平刷新频率范围，其单位为kHz。这个设置值会同时指出是否在此显示器中使用特定的Modeline值。

 

四、显卡 

   1: Section "Device"
   2:   BoardName    "VMWARE0405"
   3:   BusID        "0:15:0"
   4:   Driver       "vmware"
   5:   Identifier   "Device[0]"
   6:   Screen       0
   7:   VendorName   "VMWare Inc"
   8: EndSection

 

五、Screen

一个显示器和一个显卡组成一个screen，用Section "Screen"描述，如：

 

   1: Section "Screen"
   2:   DefaultDepth 16
   3:   SubSection "Display"
   4:     Depth      15
   5:     Modes      "800x600" "768x576" "640x480"
   6:   EndSubSection
   7:   SubSection "Display"
   8:     Depth      16
   9:     Modes      "800x600" "768x576" "640x480"
  10:   EndSubSection
  11:   SubSection "Display"
  12:     Depth      24
  13:     Modes      "800x600" "768x576" "640x480"
  14:   EndSubSection
  15:   SubSection "Display"
  16:     Depth      8
  17:     Modes      "800x600" "768x576" "640x480"
  18:   EndSubSection
  19:   Device       "Device[0]"
  20:   Identifier   "Screen[0]"
  21:   Monitor      "Monitor[0]"
  22: EndSection
 

其中，

Identifier：定义一个“Screen”名称，以便在“ServerLayout”Section中进行参照。

Device：指定“Device”Section中的名称。

Monitor：指定“Monitor”Section中的名称。

DefaultDepth：默认的色深（Color Depth）位数。

Modes "800x600" "768x576" "640x480" 表示系统会默认先按照800x600的分辨率去适配，如果适配失败，则选择768x576的分辨率继续。

 

六、Modes 

   1: Section "Modes"
   2:   Identifier   "Modes[0]"
   3:   Modeline      "800x600" 35.55 800 832 912 1024 600 601 604 620
   4:   Modeline      "768x576" 33.74 768 792 872 976 576 577 580 596
   5:   Modeline      "640x480" 23.86 640 656 720 800 480 481 484 497
   6: EndSection

 

和screen章节中的Modes对应。

 

7、ServerLayout 

   1: Section "ServerLayout"
   2:   Identifier   "Layout[all]"
   3:   InputDevice  "Keyboard[0]" "CoreKeyboard"
   4:   InputDevice  "Mouse[1]" "CorePointer"
   5:   Option       "Clone" "off"
   6:   Option       "Xinerama" "off"
   7:   Screen       "Screen[0]"
   8: EndSection

ServerLayout”Section主要用于建立X Server启动时的外观，其中：

Identifier：此ServerLayout Section的惟一名称。

Screen：“Screen”Section指定的名称

InputDevice：在X Server中的“InputDevice”Section名称。通常在此仅有两行设置，即Mouse[0]和Keyboard[0]，也就是系统中的第一个鼠标和键盘，而其他的设备大多可以忽略。
