家里的上网本10英寸屏幕,太小,看电影需要效果,想接到大点的液晶上看,直接插上,本子没啥反应,搜索发现,需要费点时间配置下:需要添加一点配置到/etc/X11/xorg.conf 好让X11识别设备,配置好后的文件如下,添加 --- 说明的地方即为添加的配置信息:

==========

添加后,外接上显示器或者投影仪,登录时选在GNOME图形化登录,即可。

如果是需要连接投影仪,那就需要双屏(笔记本和投影仪)都能显示,而且显示的完全一样,必须添加如下(黑体为添加的):

Section "Screen"

Identifier"Screen0"

Device"Device0"

Monitor"Monitor0"

DefaultDepth24

Option"AddARGBGLXVisuals""True"

Option"TwinView""true"

Option"TwinViewOrientation""Clone"

Option"UseEdidFreqs""True"

#Option"metamodes""1280x800_60+0+0"

SubSection"Display"

Depth24

EndSubSection

EndSection

注:以上是nVidia下的配置,如果是ati,可能不大一样。
