基于VirtualBOX的OracleLinux分辨率設置

在基于Virtual BOX的Oracle Linux上布署11G RAC，執行grid Infrastructure 集群件安裝的時候，OUI界面顯示不全，右下角缺少next與cancel按鈕，顯示如下 點擊System--Administrator--Display，將分辨率由640x480調整至800x600，然后logout重新登陸，問題依舊

在基于Virtual BOX的Oracle Linux上布署11G RAC，執行grid Infrastructure 集群件安裝的時候，OUI界面顯示不全，右下角缺少"next"與"cancel"按鈕，顯示如下

點擊"System"-->"Administrator"-->"Display"，將分辨率由640x480調整至800x600，然后logout重新登陸，問題依舊。

編輯/etc/X11/xorg.cnf文件，設置分辨率參數Modes，顯示如下

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

然后重啟系統，問題依舊，并且點擊"System"-->"Administrator"-->"Display"，發現可選分辨率還是只有640x480和800x600。

百度了一下，網上說要安裝Virtual Box增強功能，具體操作如下

點擊“安裝增強功能”后，桌面會出現VBOXADDITIONS _4.3.10_93012光盤圖標，點擊圖標后，找到“VBOXLinuxAdditions.run”文件

雙擊運行，屏幕輸出以下信息

Verifying archive integrity... All good.

然后重啟系統解決問題。

備注：如果雙擊“VBOXLinuxAdditions.run”文件，屏幕沒有輸出上面的信息，可以在命令行下進去文件所在路徑，以root用戶執行。
