多屏问题

多屏问题

大家好,我刚刚安装了 Ubuntu 16.04 LTS,我的电脑使用英特尔显卡,有两个显示器。但我检测不到第二台显示器。

xrander 输出:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
DP1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
VGA1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
   1920x1080     60.00*+
   1680x1050     59.95  
   1600x900      60.00

   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   640x480       75.00    72.81    66.67    60.00  
   720x400       70.08  
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

xrandr 使用两个监视器进行输出:

Screen 0: minimum 8 x 8, current 3200 x 1080, maximum 32767 x 32767
DP1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected 1280x1024+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm

   1280x800      59.81  
   1152x864      75.00  
   1280x720      60.00  
   1024x768      75.08    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   640x480       75.00    72.81    66.67    60.00  
   720x400       70.08  
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

有什么建议吗?

根据xrandr您发布的输出,您的显卡或驱动程序似乎不支持 DVI 输出。请尝试使用其他输出之一,并编写一个简单的xrandr脚本来在登录时配置您的显示器。

我的登录脚本只有一行,如下所示:

xrandr --output VGA-0 --left-of DVI-0 --primary

我将其命名为 lxde-setup.sh 并将其添加到启动操作中。
