基于Virtual BOX的Oracle Linux分辨率设置

在基于Virtual BOX的Oracle Linux上布署11G RAC，执行grid Infrastructure 集群件安装的时候，OUI界面显示不全，右下角缺少next与cancel按钮，显示如下 点击System--Administrator--Display，将分辨率由640x480调整至800x600，然后logout重新登陆，问题依旧

在基于Virtual BOX的Oracle Linux上布署11G RAC，执行grid Infrastructure 集群件安装的时候，OUI界面显示不全，右下角缺少"next"与"cancel"按钮，显示如下

点击"System"-->"Administrator"-->"Display"，将分辨率由640x480调整至800x600，然后logout重新登陆，问题依旧。

编辑/etc/X11/xorg.cnf文件，设置分辨率参数Modes，显示如下

div "InputDevice"
  Identifier   "Keyboard[0]"
  Driver       "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"
  Option       "Protocol" "Standard"
  Option       "CoreKeyboard"
Enddiv


div "InputDevice"
  Driver       "mouse"
  Identifier   "Mouse[1]"
  Option       "Buttons" "9"
  Option       "Device" "/dev/input/mice"
  Option       "Name" "VirtualBox Mouse Buttons"
  Option       "Protocol" "explorerps/2"
  Option       "Vendor" "Oracle Corporation"
  Option       "ZAxisMapping" "4 5"
  Option       "CorePointer"
Enddiv


div "InputDevice"
  Driver       "vboxmouse"
  Identifier   "Mouse[2]"
  Option       "Device" "/dev/vboxguest"
  Option       "Name" "VirtualBox Mouse"
  Option       "Vendor" "Oracle Corporation"
  Option       "SendCoreEvents"
Enddiv


div "ServerLayout"
  Identifier   "Layout[all]"
  InputDevice  "Keyboard[0]" "CoreKeyboard"
  InputDevice  "Mouse[1]" "CorePointer"
  InputDevice  "Mouse[2]" "SendCoreEvents"
  Option       "Clone" "off"
  Option       "Xinerama" "off"
  Screen       "Screen[0]"
Enddiv


div "Monitor"
  Identifier   "Monitor[0]"
  ModelName    "VirtualBox Virtual Output"
  VendorName   "Oracle Corporation"
Enddiv


div "Device"
  BoardName    "VirtualBox Graphics"
  Driver       "vboxvideo"
  Identifier   "Device[0]"
  VendorName   "Oracle Corporation"
Enddiv


div "Screen"
  Subdiv "Display"
    Depth      24

    Modes "1024x768" "800x600" "640x480"
  EndSubdiv
  Device       "Device[0]"
  Identifier   "Screen[0]"
  Monitor      "Monitor[0]"
Enddiv

然后重启系统，问题依旧，并且点击"System"-->"Administrator"-->"Display"，发现可选分辨率还是只有640x480和800x600。

百度了一下，网上说要安装Virtual Box增强功能，具体操作如下

点击“安装增强功能”后，桌面会出现VBOXADDITIONS _4.3.10_93012光盘图标，点击图标后，找到“VBOXLinuxAdditions.run”文件

双击运行，屏幕输出以下信息

然后重启系统解决问题。

备注：如果双击“VBOXLinuxAdditions.run”文件，屏幕没有输出上面的信息，可以在命令行下进去文件所在路径，以root用户执行。
