vnc4server. Daemon working. autostart not working

Question

I have a Parrot OS Linux installed on my raspberry pi 3. I installed a VNC server using vnc4server and after some fight with ~/.vnc/xstartup file is working fine with my xfce4 Desktop Environment:

xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
startxfce4 &

I made a daemon (here it is) which is on /etc/init.d and has 755 permissions. The daemon works fine if you execute it manually /etc/init.d/vncboot start|stop|restart . Some example output:

#/etc/init.d/vncboot restart
Stopping VNC Server
Killing Xvnc4 process ID 6663

Starting VNC Server

New 'station:1 (root)' desktop is station:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/station:1.log

And after that, I can connect without any problem. I already executed update-rc.d vncboot enable in order to try to start this automatically... but the problem is after a reboot, I try to connect to VNC server and some errors appear. Sorry because the errors are in Spanish:

Anyway, If I use the daemon /etc/init.d/vncboot restart the errors disappear and it works again connecting fine. This is the VNC server log when it has errors on reboot: Log

Where is my problem? on daemon config? On xserver config? On vncserver config? Even is valid to me the "dirty trick" of automatize a command using the daemon restart on every boot if possible because the daemon makes it work. Any idea would be appreciated.

Answer 1

I'm going to answer myself... I found a solution. Maybe useful for others...

I created a script on /etc/rc5.d because is the last runlevel to start... and the script was called S99vncboot. The 99 is because I want it to be executed in the end. After put it permissions 755 with chmod, the script has this content:

#!/bin/bash
sleep 30
/etc/init.d/vncboot restart

With this, the daemon is restarted after reboot and after 30 seconds... which made it work.
