主机为Dell Optiplex990，双显卡，intel集显接一显示器记为dell-0，ati x600接两个显示器记为ibm-0和ibm-1，发行版为Archlinux，桌面环境为gnome3.6
代码:
$lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV380 [Radeon X600 (PCIE)]
由于xrandr 1.3+ 不支持双显卡，转为Xinerama方案配置。ibm-0和ibm-1都是1024x768，dell-0是1366x768
希望配置成从左至右：
ibm-0,dell-0,ibm-1以下是配置文件

$cat /etc/X11/xorg.conf.d/10-monitor.conf

配置完以后，进入gnome是这么个德性

本应该在ibm-0上显示的内容显示到dell-0上去了，把dell-0的内容往右挤了1024像素，如果把尝试把窗口拖到ibm-0上，拖过去的窗口就会显示在dell-0左边的1024个像素里，而且在dell-0上无法进行交互，只有把鼠标焦点移到ibm-0上才可以操作dell-0左边1024像素的内容，相当于显示错了，但是操作是有效的
