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。

下面是一个完整的配置好的拖机的配置：
注意代码中有我添加的说明注释！

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。
