Redhat 5.6 雙顯示器 xorg.conf 設(shè)置

發(fā)布時間:2013-10-14 03:02:52來源:紅聯(lián)作者:121993446

筆者工作站為DELL T7600，兩個顯示器1920*1200.配置成雙屏擴展模式。使用中出現(xiàn)問題：用戶模式下，只能一個屏幕顯示。Nvidia-settings設(shè)置中，第二個屏幕為off。手動修改啟用，并保存到xorg.conf，提示無修改權(quán)限。但是在其他用戶下，雙屏可以正常顯示。

解決方案：修改xorg.conf

要點：serverLayout中設(shè)置成雙頭顯示，默認(rèn)的顯示器為screen0，添加的screen1 要給出定義。還有 monitor0，monitor1.videocard0，videocard1.“1”語句復(fù)制“0”的即可。配置之后，logout。如果提示無法進入桌面，會提示語句不完整。按提示的錯誤信息進行更改。
