🍀设置虚拟显示屏
安装xserver-xorg
sudo apt-get install xserver-xorg-core-hwe-18.04
sudo apt-get install xserver-xorg-video-dummy
增加xorg配置文件,通过指令vim /usr/share/X11/xorg.conf.d/xorg.conf
,添加以下内容。
Section "Monitor"Identifier "Monitor0"HorizSync 28.0-80.0VertRefresh 48.0-75.0Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
EndSection
Section "Device"Identifier "Card0"Driver "dummy"VideoRam 256000
EndSection
Section "Screen"DefaultDepth 24Identifier "Screen0"Device "Card0"Monitor "Monitor0"SubSection "Display"Depth 24Modes "1920x1080_60.00"EndSubSection
EndSection
重启机器
重启后自动启用虚拟显示屏,如果之后再需要用显示器,将/usr/share/X11/xorg.conf.d/xorg.conf
文件移除,再重启机器即可。
