Redhat 5.6 双显示器 xorg.conf 设置

发布时间:2013-10-14 03:02:52来源:红联作者:121993446

笔者工作站为DELL T7600，两个显示器1920*1200.配置成双屏扩展模式。使用中出现问题：用户模式下，只能一个屏幕显示。Nvidia-settings设置中，第二个屏幕为off。手动修改启用，并保存到xorg.conf，提示无修改权限。但是在其他用户下，双屏可以正常显示。

解决方案：修改xorg.conf

要点：serverLayout中设置成双头显示，默认的显示器为screen0，添加的screen1 要给出定义。还有 monitor0，monitor1.videocard0，videocard1.“1”语句复制“0”的即可。配置之后，logout。如果提示无法进入桌面，会提示语句不完整。按提示的错误信息进行更改。
