ubuntu：

无显示器VNC控制

二、centos系统vnc配置

注：
如果配置的普通用户，则远程连接端和原桌面的显示不一致。若需要与原桌面一致，则需要配置root用户，同时server端也要登陆root用户，在设置中开启屏幕共享，并禁用VNC Server的加密。

yum install dconf
dconf-editor
# 在dconf-editor中，展开->org->desktop->remote-access
# 取消选中require-encryption

三、jetson agx orin vnc配置

3.1 vino

sudo apt install vino
gsettings set org.gnome.Vino prompt-enabled false

gsettings set org.gnome.Vino require-encryption false
cd /usr/share/glib-2.0/schemas

sudo cp org.gnome.Vino.gschema.xml org.gnome.Vino.gschema.xml.old

sudo vi org.gnome.Vino.gschema.xml 

添加：

<key name='enabled' type='b'>
      <summary>Enable remote access to the desktop</summary>
      <description>
              If true, allows remote access to the desktip via the RFB
              protocol. Users on remote machines may then connect to the
              desktop using a VNC viewer.
      </description>
      <default>false</default>
    </key>

sudo glib-compile-schemas /usr/share/glib-2.0/schemas
/usr/lib/vino/vino-server

3.2 tigervnc

sudo apt install tigervnc-standalone-server
# 不要使用sudo执行vncpasswd
vncpasswd
sudo nano ~/.vnc/xstartup
#!/bin/sh

unset SESSION_MANAGER

unset DBUS_SESSION_BUS_ADDRESS

exec startxfce4

chmod u+x ~/.vnc/xstartup
vncserver
vncserver -list
vncserver -kill :1
vncserver -localhost no -geometry 1280x720 -depth 24

四、共享文件配置

4.1安装samba

sudo apt update
sudo apt install samba

4.2创建共享文件夹

sudo mkdir /home/shared
sudo chmod 777 /home/shared

4.3编辑samba配置文件

sudo nano /etc/samba/smb.conf

[shared]
path = /home/shared
writable = no  # 设置为不可写
guest ok = yes
guest only = yes
create mask = 0555  # 设置文件的默认权限为只读
directory mask = 0555  # 设置目录的默认权限为只读
# 在复制时，删除注释，否则会报错

4.4重启samba服务

sudo service smbd restart

五、 无显示器VNC控制

5.1安装并配置虚拟桌面

sudo apt update
sudo apt install xserver-xorg-video-dummy

cd /usr/share/X11/xorg.conf.d
sudo gedit xorg.conf

Section "Device"
    Identifier "DummyDevice"
    Driver "dummy"
    VideoRam 256000
EndSection
 
Section "Screen"
    Identifier "DummyScreen"
    Device "DummyDevice"
    Monitor "DummyMonitor"
    DefaultDepth 24
    SubSection "Display"
        Depth 24
        Modes "1920x1080_60.0"
    EndSubSection
EndSection
 
Section "Monitor"
    Identifier "DummyMonitor"
    HorizSync 30-70
    VertRefresh 50-75
    ModeLine "1920x1080" 148.50 1920 2448 2492 2640 1080 1084 1089 1125 +Hsync +Vsync
EndSection

sudo reboot
