Virtualbox安装CentOS修改分辨率

一般Virtualbox安装CentOS安装完成后默认是800x600的分辨率。

安装Guest additions。安装完成后，分辨率可以修改为1024x768，还有一些更高的分辨率，但是没有1366x768。

修改/etc/X11/xorg.config

安装完Guest additions后，文件默认内容为(或者类似)

# VirtualBox generated configuration file

# based on /etc/X11/xorg.conf.

Section "Monitor"

Identifier "Monitor[0]"

ModelName "VirtualBox Virtual Output"

VendorName "Oracle Corporation"

EndSection

Section "Device"

BoardName "VirtualBox Graphics"

Driver "vboxvideo"

Identifier "Device[0]"

VendorName "Oracle Corporation"

EndSection

Section "Screen"

SubSection "Display"

Depth 24

EndSubSection

Device "Device[0]"

Identifier "Screen[0]"

修改Section "Screen"，添加字段Modes "800x600" "1366x768" （可添加需要的任意分辨率）

Section "Screen"

SubSection "Display"

Depth 24

Modes "800x600" "1366x768"

EndSubSection

Device "Device[0]"

Identifier "Screen[0]"

注意：Modes要添加在SubSection之间，而且不能只添加1366x768，要同时添加800x600。
