Ok started with a new image
I did all what I stated above +
only left
99-fbturbo.conf in
/zynthian/zynthian-sys/etc/X11/xorg.conf.d
removing the 3.2 tft and the associatted touch
then added this file
sudo nano /usr/share/X11/xorg.conf.d/99-fbdev.conf
Section "Device"
Identifier "touchscreen"
Driver "fbdev"
Option “fbdev” "/dev/fb0"
EndSection
and voila!!
now the middle (list section) is working and touch sensitive but the 4 side controllers do not 
!
I am wondering if it has to do with
Wiring layout
hw_version=“PROTOTYPE-4”
since I don’t have any “physical” Zynthian hardware should I write sth else?
Thanks !
