如何让ubuntu10.04跨4个显示器显示

[testdemo]

大家好。我在ubuntu10.04下面需要连接4个显示器。目前驱动都安装好了，显卡是nvidia的双头显示器。目前每个屏幕显示成了一个桌面，我想让通过配置xorg.conf来让4个显示器显示成一个大的桌面。知道的兄弟帮帮忙。目前同一个显卡的两个显示器可以设置成twinview模式，但是这样就会有两个屏幕，我想只显示一个模式。不知道描述清楚没有。谢谢！

xorg.conf配置如下：
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 275.21 (buildmeister@swio-display-x86-rhel47-02.nvidia.com) Mon Jul 18 15:02:03 PDT 2011

两显卡 四个屏 显一个桌面

是有两张双头的nvidia显卡，接了4个显示器。我想让四个显示器扩展成一个桌面。

顶上去，不要沉。期待高手

我过去研究窗口管理器时，无意中找到一个英文的资料，就是做这个的，可惜已经忘记怎么做到的了。
只记得就是修改xorg.conf，定义4个Monitor段（4个显示器），并且在Monitor段里面加一个参数指定序号和先后关系：2前面是1,3前面是2....n前面是1,形成一个循环。

并且还知道有一个bug：窗口最大化时，可能会一次充满4个屏幕，需要补丁（也许现在已经解决这个bug了）

有办法做到的。

我现在的鼠标能穿透4个桌面。但是我最大化一个窗口的时候，只能在其中一个显示器上全屏，不能做到全屏铺满四个显示器。楼上的方法我先试试。

不要沉，顶起来，期待高手。

楼主，你的问题解决没有，我也碰到类似问题，18.04版本，外接4个显示器，最大化窗口只能充满一个屏幕；盼分享经验！
