 Kodi will not start automatically at boot, just execute **kodi-standalone** from the command line.
-**NOTICE**: Raspbian includes **Kodi version 17.6** whereas Debian Stretch has Kodi 17.1, so beware of what packages you are installing and respect the right dependencies.
+**NOTICE**: Raspbian based on **Debian Stretch 9.11** uses two repositories:
+  * **[[http://raspbian.raspberrypi.org/raspbian/]]** (by file /etc/apt/sources.list)
+  * **[[http://archive.raspberrypi.org/debian/]]** (by file /etc/apt/sources.list.d/raspi.list)
+The first repository provides **Kodi 17.1** as per Debian Stretch. The second repository provided **Kodi version 17.6** on December 2017, but it was upgraded to **Kodi version 18** on february 2019. So beware of what packages you are installing, respect the right dependencies and be carefull with upgrades.
+Our current installation uses these versions:
+^ kodi                         | 2:17.6-2~stretch  |
+^ kodi-bin                     | 2:17.6-2~stretch  |
+^ kodi-eventclients-common     | 2:18.1-1~stretch  |
+^ kodi-eventclients-kodi-send  | 2:18.1-1~stretch  |
+^ kodi-peripheral-joystick     | 1.3.4-1~stretch   |
+^ libkodiplatform17:armhf      | 17.4.0~stretch    |
+To activate a joypad you have to go through **//Settings//** => //System settings// => //Input// => **//Configure attacched controllers//**.

 To confirm that the video codec is VP8, we installed the **mediainfo** package an run the tool against the video; which actually uses the VP8 codec. The official **[[http://kodi.wiki/view/Raspberry_Pi_FAQ|Kodi Wiki]]** says that VP8 is supported on the Raspberry Pi architecture, so we are searching for the problem somewhere else.
-[[https://forum.kodi.tv/showthread.php?tid=204239|This post]] says that VP8 hardware (GPU) decoding is supported only if run from **startx**: //Note that GPU accelerated software codecs (and camera) are only available from start_x.elf. Add start_x=1 to config.txt (or use raspi-config and enable camera)//.
+**[[https://forum.kodi.tv/showthread.php?tid=204239|This post]]** says that VP8 hardware (GPU) decoding is supported only if firmware **start_x.elf** is loaded: //Note that GPU accelerated software codecs (and camera) are only available from start_x.elf. Add start_x=1 to config.txt (or use raspi-config and enable camera)//. This means that we have to add the following line in **/boot/config.txt** (The required file is already in the ''/boot'' directory):
+<file>
+start_x=1
+</file>
-FIXME: So we have to revise the boot procedure? Need to install xserver.xorg and change the Kodi service?
+See also the page **[[https://www.raspberrypi.org/documentation/configuration/config-txt/boot.md|Boot options in config.txt]]**. We have also **gpu_mem=128** in the same config file.
