Kubuntu and VNC as a service

I've been setting up an old laptop so that I can use it with my new radio as a remote station.

Latest Kubuntu uses fucking useless Wayland so VNC doesn't work well. TightVNC fails to start up anything useful so forcing X11 is a necessity.

This is a good solution. Found it on Reddit.# install x11vnc

sudo apt install x11vnc

# set a VNC password. VNC security is lacking, so this is optional.

sudo x11vnc -storepasswd /etc/x11vnc.passwd

# follow the prompts to create a password and then lock down the password file.

sudo chmod 0400 /etc/x11vnc.passwd

# would be nice if there was an service created for x11vnc, but there isn't so create one.

sudo nano /etc/systemd/system/x11vnc.service

# paste the following text block into into /etc/systemd/system/x11vnc.service

# If you are NOT using a password, then remove this section: -rfbauth /etc/x11vnc.passwd

[Unit]
Description=Start x11vnc
After=multi-user.target display-manager.service

[Service]
Type=simple

ExecStart=/bin/sh -c '/usr/bin/x11vnc -display :0 -forever  -rfbport 5900 -xkb -noxrecord -noxfixes -noxdamage -nomodtweak -repeat -shared -norc -auth /var/run/sddm/* -rfbauth /etc/x11vnc.passwd'

# For KDE ONLY, include the "Restart" and "RestartSec" commands, otherwise you could just use "-loop" but that is busted since at least kubuntu 18.04
# This was added because logging out killed the x11vnc session even though "-loop -forever" was enabled.
# NOTE: In order to use this, make sure "-loop" switch is not used above!!
# NOTE: While vnc client will disconnect, at least the vncserver will restart itself to client can connect again.
Restart=always
RestartSec=1

ExecStop=/usr/bin/killall x11vnc

[Install]
WantedBy=multi-user.target

# reload systemd with the brand new x11vnc service file

sudo systemctl daemon-reload

# start x11vnc service so you can use it now

sudo systemctl start x11vnc

# enable x11vnc to start at boot so you can use it later

sudo systemctl enable x11vnc
