使opensuse12.1实现一拖二（拖机）的双人使用系统（下）

继续上篇的介绍。本章贴配置代码。

对于KDE环境来说主要配置以下两个文件：

/etc/x11/xorg.conf
/usr/share/kde4/config/kdm/kdmrc

先说xorg.conf，这个文件在新安装好系统后并不存在，我是在安装好nvidia驱动后，配置好显卡后保存的这个文件。这是一个最开始配置好的文件内容：
这个是已经配置好双头显示的文件。

 

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 295.49  ([email protected])  Tue May  1 00:35:28 PDT 2012

#这是一个由nvidia X window settings配置好的xorg.conf文件

#以上代码配置鼠标和键盘
#Keyboard0和mouse0是一对配套使用的键盘和鼠标
#注意鼠标的driver有“mouse”和“evdev”两种，我的用“mouse”可以正常工作
#注意鼠标中Option "Protocol" "auto"
#的“auto”改为 "ExplorerPS/2"，鼠标滚轮才可正常工作
#可以用命令：ls /dev/input/mouse*列出所有鼠标
#命令：more /proc/bus/input/devices 列出所有键盘鼠标及 键盘的event 的ID号。

其次是kdmrc文件，配置如下：

#/usr/share/kde4/config/kdm/kdmrc

[General]
ConfigVersion=2.4
SUSEConfigVersion=2
StaticServers=:0,:1
ReserveServers=:2,:3
ServerVTs=-7
ConsoleTTYs=tty1,tty2,tty3,tty4,tty5,tty6

[Xdmcp]

[Shutdown]


[X-*-Core]
ClientLogFile=.xsession-errors-%d

[X-*-Greeter]
LogoPixmap=/usr/share/kde4/apps/kdm/pics/kdelogo.png
MinShowUID=500
MaxShowUID=65000
ForgingSeed=1268675635
UseTheme=true

[X-:*-Core]

[X-:*-Greeter]
PreselectUser=Previous
FocusPasswd=true
LoginMode=DefaultLocal
AllowClose=false

#主要是下面两个设置，有仔细解说了
[X-:0-Core]
TerminateServer=true
ClientLogFile=.xsession-errors
ServerArgsLocal=-nolisten tcp -layout Layout0 -sharevts -novtswitch

[X-:1-Core]
TerminateServer=true
ClientLogFile=.xsession-errors
ServerArgsLocal=-nolisten tcp -layout Layout1 -sharevts -novtswitch

[X-:93-Core]
TerminateServer=true

[X-:0-Greeter] 

如果想要GNOME也能成功拖机还要修改下面这个文件：

 /etc/gdm/custom.conf
反正我是两下环境下拖机都成功了。稍微注意看下就懂了。

# GDM configuration storage
#
# Note: settings from /etc/sysconfig/displaymanager have a higher priority
#

[servers]
0=Standard0
1=Standard1
[server-Standard0]
name=Standard server
command=/usr/X11R6/bin/X -nolisten tcp -novtswitch -sharevts -layout Layout0
flexible=true
[server-Standard1]
name=Standard server
command=/usr/X11R6/bin/X -nolisten tcp -novtswitch -sharevts -layout Layout1
flexible=true

[xdmcp]

[greeter]

[chooser]

[debug]

好了，完 了，有想拖机的朋友可以做个参考。
