Why x0vncserver is not starting at boot

bootsystemdtightvnc

I tried to make my tightvncserver start at boot on parabola arch Gnu/Linux in an auto GUI login setup using the wiki https://wiki.archlinux.org/index.php/TigerVNC#Using_tigervnc.27s_x0vncserver and by creating x0vncserver.service systemd unit following that and then systemctl enable x0vncserver.service but when I boot/reboot, I see no vnc server active and then checking I see this

# systemctl status x0vncserver.service
* x0vncserver.service - Remote desktop service (VNC)
   Loaded: loaded (/etc/systemd/system/x0vncserver.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Sat 2017-07-01 20:42:55 +06; 1min 34s ago
  Process: 302 ExecStart=/usr/bin/sh -c /usr/bin/x0vncserver -display :0 -rfbport 5900 -passwordfile /home/peruvian/.vnc/passwd & (code=exited, status=0/SUCCESS)

Jul 01 20:42:52 sky systemd[1]: Starting Remote desktop service (VNC)...
Jul 01 20:42:55 sky systemd[1]: Started Remote desktop service (VNC).

and my 

# journalctl -xe | grep vnc
-- Subject: Unit x0vncserver.service has begun start-up
-- Unit x0vncserver.service has begun starting up.
-- Subject: Unit x0vncserver.service has finished start-up
-- Unit x0vncserver.service has finished starting up.

Jul 01 20:47:08 sky systemd[1]: x0vncserver.service: Failed with result 'exit-code'.

But if I run the command systemctl start x0vncserver.service or systemctl restart x0vncserver.service after loading the desktop, it works without any issue as the # systemctl status x0vncserver.serviceshows

# systemctl status x0vncserver.service

and my default.target is 

# systemctl get-default       
graphical.target

I guess the service starts earlier than it supposed to and fails due to lack of resources at boot.

Best Answer

As x0vncserver will only start after xsession, and as mine is an LXDE environment, the easier way is to create a script.sh file like following

#!/bin/bash
x0vncserver -display :0 -rfbport 5900 -passwordfile ~/.vnc/passwd

and make it executable by sudo chmod +x script.sh and add a line in ~/.config/lxsession/LXDE/autostart file like following

path_to_the_script_file/script.sh

and the x0vncserver starts as my LXDE desktop session starts and that's what I need.
