Guys,

I would like to update this post because like me maybe he has the latest NUC model and he's gone crazy.
So I've solved it using a couple of "tricks" that I don't like but that work

I hope that the user (and that I thank him again with all my heart for his infinite patience and goodness) @fritsch does not want to shoot me and that if maybe I'm saying crap to correct me and I try to summarise the steps I have taken (I hope to remember them in the correct order):


Installation
-1.) Hardware and software :
       - NUC10i7FNH
       - OS Ubuntu Server 19.10
       - Kernel : 5.5.8-050508-generic

0.) Basic Installation and script tuning

sudo apt-get install ssh software-properties-common xorg xserver-xorg-legacy alsa-utils mesa-utils git-core librtmp1 libmad0 lm-sensors libmpeg2-4 avahi-daemon libnfs12 libva2 vainfo  intel-media-va-driver-non-free linux-firmware dbus-x11 udisks2 openbox pastebinit udisks2 xserver-xorg-video-intel  xserver-xorg-video-intel
sudo apt-get dist-upgrade 

This is really very important for my system otherwise the hardware acceleration doesn't work.
sudo sh -c "echo 'LIBVA_DRIVER_NAME=iHD' >> /etc/environment"

sudo chmod -R 777 /dev/dri
sudo chmod -R 777 /dev/dri/*

sudo nano etc/modprobe.d/i915.conf

options i915 enable_guc=2 enable_psr=0

sudo apt remove gdm3
sudo apt remove pulseaudio

Allow "everyone" to start the Xserver

sudo dpkg-reconfigure xserver-xorg-legacy ->everyone
sudo nano /etc/X11/Xwrapper.config -> needs_root_rights=yes

cat /etc/X11/xorg.conf.d/20intel.conf

Section "Device"
  Identifier  "Device0"
  Driver      "intel"
  VendorName  "INTEL Corporation"
  Option "AccelMethod" "sna"
  Option "TripleBuffer" "false"
  Option "TearFree" "false"
  Option "DRI" "3"
EndSection
Section "Extensions"
  Option "Composite" "Disable"
EndSection

sudo adduser kodi
sudo usermod -a -G cdrom,audio,video,plugdev,users,dialout,dip,input,disk kodi

sudo nano /etc/polkit-1/localauthority/50-local.d/custom-actions.pkla

[Actions for kodi user]
Identity=unix-user:kodi
Action=org.freedesktop.login1.*;org.freedesktop.udisks2.*

[Untrusted Upgrade]

Action=org.debian.apt.upgrade-packages;org.debian.apt.update-cache
ResultAny=yes

ResultActive=yes

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

[Unit]
Description = kodi-standalone using xinit
Requires = dbus.service
After = systemd-user-sessions.service sound.target network-online.target
 
[Service]
User = kodi
Group = kodi
Type = simple
PAMName=login
ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/openbox-session -- :0 -nolisten tcp vt7
Restart = on-abort
 
[Install]
WantedBy = multi-user.target

 
sudo nano /etc/security/limits.conf

kodi             -       nice            -1

1.) Now we install the kodi in nightly version:

sudo add-apt-repository ppa:team-xbmc/xbmc-nightly
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install kodi kodi-x11

As we use openbox as our display manager, we need to auto start kodi, therefore create:

sudo mkdir -p /home/kodi/.config/openbox
sudo touch /home/kodi/.config/openbox/autostart
sudo chown kodi:kodi /home/kodi/.config -R

cat /home/kodi/.config/openbox/autostart

OUTPUT=`xrandr -display :0 -q | sed '/ connected/!d;s/ .*//;q'`
xrandr -display :0 --output $OUTPUT --set "Broadcast RGB" "Full"
xsetroot #000000
xset s off -dpms
/usr/bin/kodi --standalone
while [ $? -ne 0 ]; do
/usr/bin/kodi --standalone
done
openbox --exit

And in my system I also had to update the graphics drivers

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade

@fritsch if I said nonsense or if the installation history is not correct, feel free to intervene and fix

thank you all
