Linux上玩了一下双显示器

发布时间:2007-08-18 00:07:13来源:红联作者:nchronous

昨天突然心血来潮，想在Linux上玩弄一下双显示器。我的NVIDIA显卡带DVI+VGA+S三个接口，其中VGA接口已被占用，不得买了一个DVI->VGA转换器来链接另外一台CRT显示器了。

操作系统：Everest Linux 0.3

显示器为：PHILIPS 170S LCD & AOC的CRT显示器(型号未知，ddcprobe出的ID是@HA0101)

显卡：NVIDIA 6600首先安装了最新的NVIDIA-Linux-x86-1.0-9755-pkg1.run驱动。在网上查找了不少帖子，据说用NVIDIA X Server Setting开启TwinView功能就能实现双屏显示。结果试用了一下，发现这个功能仅仅是将屏幕水平延伸，即如果把某个程序最大化后，将分割扩展到两个显示器上。这不是我要实现的将两个屏幕设置成显示不同的桌面。后来发现在NVIDIA X Server Setting中还有一个选项Separate X screen选项，试了一下，重启X后，确实实现了我想要的效果。不过当我点击鼠标右键，或者进行其他的操作的时候，X会莫名的重启。郁闷不已，只能动手修改xorg.conf配置文件了。下面就是我修改后的xorg.conf的内容了。我将其中修改过的部分Highlight出来。
