前两天为了工作需要,打算用我的ATI X600双头显卡接两个显示器,显示同样的内容,鼓捣了一番,记录于此。
ubuntu默认的双头显卡是左右屏的方式,即主屏是正中央,第二个屏在右边,对应xorg.conf中是这样的:
Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" 0 0 Screen "aticonfig-Screen[1]" RightOf "Default Screen" 其中Default Screen就是主屏,aticonfig-Screen[1]是第二个显示器。RightOf是设定在主屏右边,还有其它值可选,在man xorg.conf里ServerLayout部分有详细解释,大概在1324行:
- RightOf 右边
- LeftOf 左边
- Above 上边
- Below 下边
但我是想显同样的内容,所以需要删除xorg.conf中的两行内容,一行就是上面贴过的:
Screen "aticonfig-Screen[1]" RightOf "Default Screen" 另外一行是和aticonfig-Screen[1]相对应的Device段中的Screen 1,比如:
Section "Device" Identifier "aticonfig-Device[1]" Driver "fglrx" BusID "PCI:1:0:0" # 2 screen same display 2/2: delete below line Screen 1 删掉上面的最后一句,然后重启X就可以了。
