There is another problem with the above method. Now restart the remote computer, and you can remotely without a monitor.

In order for both the virtual monitor and the real monitor to work, we need to change the top ServerLayout In this way, we created a virtual display using a virtual graphics card. # Add 16:9 modes, others are automatically detected. Sudo apt install xserver-xorg-video-dummyĪdd the following at the end of this file When the host has no display, the system will use this virtual display.

Next, we will add a virtual display to the system. This file ensures that the system interface can be displayed normally on the monitor when the monitor is inserted on the host computer. # Values: : integer, : float, : 'True'/'False',Ĭopy this file to/usr/share/X11/xorg. new fileįontPath '/usr/share/fonts/X11/100dpi/:unscaled'įontPath '/usr/share/fonts/X11/75dpi/:unscaled' In order to ensure that the remote host can be accessed remotely through VNC regardless of whether it has a monitor or not, we also need to make the following modifications service and write the followingĮxecStart=/usr/bin/x11vnc -auth /run/user/1000/gdm/Xauthority -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pass -rfbport 5900 -sharedĪt this time, if the monitor is connected to the remote host, it can be accessed through VNC in the LAN. Sudo x11vnc -storepasswd /etc/x11vnc.passĬreat/etc/systemd/system/x11vnc. The following operations can work normally when the host has and does not have a monitor. The VNC installation mode like 1 cannot be used when the host is not plugged into the monitor. Remote control of Ubuntu 20.04 with VNC can be achieved by following the instructions in this article.

Install x11vnc ubuntu 20.04
