手动调整分辨率，首先要得到分辨率的表示字符串。然后修改/etc/X11/xorg.conf配置文件。

1.命令行：cvt

如我想设置1280*1024，刷新75，于是输入 cvt 1280 1024 75 回车，得到的Modeline信息才是我们需要的，如：

cvt 1280 1024 75

# 1280x1024 74.90 Hz (CVT 1.31M4) hsync: 80.30 kHz; pclk: 138.75 MHz

Modeline "1280x1024_75.00" 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync

复制Modeline这一行。

2.命令行：sudo gedit /etc/X11/xorg.conf 在此文件加入如下内容:

Section "Monitor"

Identifier "Configured Monitor"

Modeline "1280x1024_75.00" 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync

Option "PreferredMode" "1280x1024_75.00"

EndSection

Section "Screen"

Identifier "Default Screen"

Monitor "Configured Monitor"

Device "Configured Video Device"

EndSection

Section "Device"

Identifier "Configured Video Device"

EndSection

其实重要的是cvt这个命令了。

另一种方法，是修改Screen这一节：下面是1440x900的例子。

sudo gedit /etc/X11/xorg.conf (注意大小写)

将下面的粘贴进去，然后保存，退出重新启动机子，

Section "Device"

Identifier "Configured Video Device"

EndSection

Section "Monitor"

Identifier "Configured Monitor"

Vendorname "Generic LCD Display"

Modelname "Monitor 1440x900"

Horizsync 31.5-60

Vertrefresh 50-60

EndSection

Section "Screen"

Identifier "Default Screen"

Monitor "Configured Monitor"

Device "Configured Video Device"

Defaultdepth 24

SubSection "Display"

Depth 24

Virtual 1440 900

Modes "1440x900@60" "1024x768@60"

EndSubSection

EndSection

以下是一个设置双屏显示的例子：

Section "ServerLayout"

InputDevice "Mouse0" "CorePointer"

Option "Xinerama" "0"

EndSection

EndSection

Section "InputDevice"

EndSection

Section "Monitor"

# HorizSync source: edid, VertRefresh source: edid
