我的目标是建立一个多头环境:我需要在两个屏幕上都有一个可用的扩展桌面,并且能够将窗口从一个屏幕拖放到另一个屏幕上。左侧屏幕位于VGA
端口上,右侧屏幕插入HDMI
端口。
我尝试尝试,xorg.conf
但似乎无法为多头工作设置正确的配置。
这是我的xorg.conf
:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"

我读了某处我需要设置Virtual
和Modes
指令,因此我修改了配置,如下所示:
Section "Screen"
# ...
SubSection "Display"
Viewport 0 0
Depth 24
Virtual 3600 1080
Modes "1920x1080" "1680x1050"
EndSubSection
EndSection
结果是主屏幕上运行的图像模糊。不过,我可以移动鼠标并看到桌面实际上已扩展。但它无法使用并且只能在一个屏幕上运行。
XRandr
我也按照以下方式安装了本文档但 的输出$ xrandr -q
是这样的:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1920 x 1200, maximum 1920 x 1200
default connected 1920x1200+0+0 0mm x 0mm
1920x1200 0.00*
1600x1200 0.00
1280x1024 0.00
1024x768 0.00
800x600 0.00
640x480 0.00
所以我看到只检测到一个屏幕,因此,我无法运行以下命令来按照我的意愿显示两个屏幕:
$ xrandr --output <RightScreen> --right-of default
因为不知道名字<RightScreen>
。
最奇怪的是,在HDMI
插入右屏幕的情况下重新启动时,启动会出现在右屏幕上,而主(左)屏幕上不会出现任何内容。当我登录时,XFCE 无法在右侧屏幕上显示任何内容,并且两个屏幕都无法使用。唯一的解决方案是手动关闭计算机(通过按按钮),拔下右侧屏幕的插头并再次启动。
我缺少什么?

这是输出$ pkg info -a -o | grep video

这也是 的输出$ sysctl hw.model hw.machine hw.ncpu
:

答案1
Vesa 不支持双显示。您需要使用本机驱动程序启动 X,在本例中为 Intel 驱动程序。
英特尔确实支持许多主板的双头。您可以通过xrandr
(临时)或xorg configuration
(重新启动持久)实现双头。
读这个。英特尔对双头设置有很好的记录
