双显卡的问题
安装的是redhat81.显卡均能正常显示，驱动正常。
2.使用startx -- +xinerama启动xwindows
3.怀疑为gnome的问题,安装了xfce后照旧.
4.只能克隆显示，两个显示器显示的一模一样，鼠标只在一个屏幕出现。
想调试为两个显示器，显示的不一样，请高手赐教，我已经折腾了一个礼拜了。实在不行了。这里先谢谢了！！！

不行啦!!!!
试startx -- :2还是一样,两个屏幕还是CLON!! :cry: You are using "nvidia" driver, which is known to have problems supporting xinerama set ups.Try "nv" driver first.But then "nv" driver will not have good 3D hardware acceleration support.Also, you might want to try KDE and see if you have the same problem.
Here's my XF86Config-4 for a dual head and a triple head display for reference.

Have fun!
问题解决了!!!!!!!谢谢huangdi
总结一下:1.不能使用NVIDIA的驱动,使用REDHAT8自带的'nv'
2.不能加载"GLX"模块
3.修改"AGP:1:0:0"为"PCI:1:0:0'
想配置双显卡的朋友可以参考:
http://www.linuxdocs.org/HOWTOs/Xinerama-HOWTO.html#toc7
再次谢谢huangdi
