Recently I am working on remote desktop control of jetson nano, Ubuntu18.04 system.
After installing Sunflower, you can operate it remotely normally.
But something went wrong during startup – starting nano without connecting to the monitor will not automatically enter the desktop graphical interface. At this time, using Sunflower to initiate remote control will display a connection error.

What caused it
Add the following content to the /etc/X11/xorg.conf configuration file (as taught by GPT):
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
After restarting, I found that the desktop still does not start automatically when the monitor is not connected, and at this time the external mouse and keyboard cannot be used (the 2.4g indicator light is not on).
GPT says this line of code is used to disable automatic addition of devices.
After deleting these lines of code and restarting the system, the mouse and keyboard can be used.
I found another article on the use of virtual monitors written by an expert on the Internet: article link
sudo apt-get install xserver-xorg-core-hwe-18.04 sudo apt-get install xserver-xorg-video-dummy-hwe-18.04 --fix-missing
After installing the related file library for using the virtual display, I found that after using this method, even if an external display is connected, the signal will not be output to the display (only the virtual display can be used, not the physical display. I am So understood).
So I stopped at this point and did not continue to follow.
But after restarting nano, the mouse and keyboard cannot be used again. I don’t know why? ? ? ?
Does anyone know where the problem is? Please help! ! !
Or is there any way to make the system skip the screen detection process and control it remotely after starting it directly? .
PS: I also followed the above article link to create /usr/share/X11/xorg.conf.d/xorg.conf and added relevant content. However, because I saw that this operation would make the physical display unusable, I changed xorg.conf The file was moved out of the xorg.conf.d directory and placed in a directory created by the desktop itself. I don’t know if it has anything to do with this.
Does anyone know how to make the mouse and keyboard work? Now I want to control the system only remotely, which is too troublesome. I look forward to your answers.
It’s just a novice operation, I really don’t understand it, I hope someone can see it

Problem Solving
After almost a month, I finally solved this problem! ! !
reason:
sudo apt-get install xserver-xorg-core-hwe-18.04
When executing the command, the system automatically uninstalls xserver-xorg-input, causing the input folder in the system’s /usr/lib/xorg/modules/ directory to be deleted, where the driver files of the input devices are stored.
solution:
sudo apt-get install xserver-xorg-input-all
Download the input device driver again, then restart the Xorg server, and the problem will be solved.
