TigerVNC [Non-headless] connection refused

Hi,

I have a server in my network with a previously working TigerVNC daemon running. Now when connecting, any device in the network gets the error message "Connection refused". I am running LightDM and Cinnamon on this setup with a physical display dummy plugged into the machine.

My current service file for x0vncserver looks as follows:

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking
User=chippey5
ExecStart=/usr/bin/sh -c 'sleep 10 && /usr/bin/x0vncserver -display :0 -geometry 1920x1080 -rfbport 5900 -passwordfile /home/chippey5/.vnc/passwd &'
Restart=always

[Install]
WantedBy=multi-user.target
#-display :0

Daemons for both LightDM show up as running:

           └─5562 sleep 10

Port 5900 is open. For some reason I am able to connect to the VNCserver when configured through LightDM (also port 5900), but then it renders in software mode, which I want to avoid.

Any ideas?

Re: TigerVNC [Non-headless] connection refused

I give your my  /etc/systemd/system/vncserver@:1.service. It works without problem.

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target
Before=lightdm.service

[Service]
Type=forking
User=yupper

ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i >/dev/null 2>&1 || true'
ExecStart=/usr/bin/vncserver
ExecStop=/usr/bin/vncserver -kill %i

[Install]
WantedBy=multi-user.target

then this is my ".vnc/xstartup"

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XDG_CONFIG_HOME=/home/yupper/vnc-xfce4

#startxfce4 &
dbus-launch xfce4-session
