参考自这里 。

双头就是接第二个显示器，或者接投影仪什么的，ati 里面叫做 bigdesktop，nvidia 叫做 twinview ，intel 的不太清楚，我记得好像也有个自己的名字。

Nvidia 的官方驱动有 twinview 的支持，图形界面下面配置起来似乎也不是很难。 ATI 的官方驱动支持的是 bigdesktop ，也有图形界面，不过那个界面很恶心，经常出现问题，不过可以试着删除 /etc/ati/amdpcsdb 文件试试看。

下面是一个 bigdesktop 的 xorg.conf 文件。

比较简单，只需要在 device 里面设置好就行了。

用 ati 的开源驱动，也可以双头显示。用下面的 xorg.conf 。

可以看到改动也不是很大，主要增加了两个显示器，device里面增加了这两个显示器的设置。另外 screen 里面增加了那个 virtual，这个的参数就是将来两个显示器总共的屏幕大小，我的是 1024+1280 x 1024 ，横向相加，竖向的取最大的。

ok，这样就可以了。注意这里没有用到最上面那个链接里面说的 MergedFB。似乎最新的 xorg 用 xrandr 实现了这个，所以 MergedFB 就不需要了。这有个好处，可以随时调整分辨率什么的。例如 xrandr –output VGA –off ，去掉第二个显示器。 xrandr –output VGA –right-of LVDS ，设置 bigdesktop等等。xrandr 的方法还可以参考这里。

升级到 xorg 1.5.3 以后，鼠标键盘的设置可以不在这里了，所以更加简单。

    最新的 fglrx 在 2.6.26 kernel 上面总出现启动黑屏，不知道哪里的问题。所以才用的 radeon。之前 fglrx 也挺好用的。

    后面这种方式还能让我的视频可以在两个显示器之间拖动。以前用 fglrx 是不行的。
