这个的解决方法就是创建远程的虚拟桌面

首先安装

$ sudo apt-get install  xserver-xorg-core-hwe-18.04
$ sudo apt-get install  xserver-xorg-video-dummy

然后加入配置文件，实现开机自启

在 /usr/share/X11/xorg.conf.d/ 中添加 xorg.conf 文件如下：

$ sudo vim /usr/share/X11/xorg.conf.d/xorg.conf
Section "Monitor"
  Identifier "Monitor0"
  HorizSync 28.0-80.0
  VertRefresh 48.0-75.0
  # https://arachnoid.com/modelines/
  # 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
  Modeline "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 24
  Identifier "Screen0"
  Device "Card0"
  Monitor "Monitor0"
  SubSection "Display"
    Depth 24
    Modes "1920x1080_60.00"
  EndSubSection
EndSection

重启即可
