ubuntu 20.04 vncserver 开机自启动 通过 sudo nano /etc/init.d/vncserver

将以下内容复制并粘贴到该文件中，然后保存并退出：

#!/bin/sh -e
# /etc/init.d/vncserver

### BEGIN INIT INFO
# Provides:          vncserver
# Required-Start:    networking
# Default-Start:     3 4 5
# Default-Stop:      0 6
### END INIT INFO

PATH="$PATH:/usr/X11R6/bin/"

# The Username:Group that will run VNC
export USER="yourusername"
#${RUNAS}
export HOME="/home/${USER}"

# The display that VNC will use
DISPLAY="1"

# Color depth (between 8 and 32)
DEPTH="16"

# The Desktop geometry to use.
#GEOMETRY="<width>x<height>"
#GEOMETRY="800x600"
#GEOMETRY="1024x768"
GEOMETRY="1280x1024"
#GEOMETRY="1440x900"
#GEOMETRY="1920x1080"

# The name that the VNC Desktop will have.
NAME="my-vnc-server"

OPTIONS="-depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY}"
. /lib/lsb/init-functions

case "$1" in
start)
log_action_begin_msg "Starting vncserver for user '${USER}' on   localhost:${DISPLAY}"
su ${USER} -c "/usr/bin/vncserver ${OPTIONS}"
;;

stop)
log_action_begin_msg "Stoping vncserver for user '${USER}' on localhost:${DISPLAY}"
su ${USER} -c "/usr/bin/vncserver -kill :${DISPLAY}"
;;

restart)
$0 stop
$0 start
;;
esac

exit 0

然后，将该文件标记为可执行文件：

sudo chmod +x /etc/init.d/vncserver

接下来，使用以下命令将该文件添加到启动脚本中：

sudo update-rc.d vncserver defaults

最后，重新启动系统以测试自启动是否成功：

sudo reboot
