Thank you William for the link, I will try this later. In between I found if I load the module in the /etc/init.d/boot.local the module is loaded 2-3s before X server starts So now X found the device /dev/fb0 (see Xorg.0.log below)
But unfortunately I still have NOTHING on the display, it's really frustrating. The login manager lightdm process is running so I should see it on the screen. After a while the LCD backlight turns OFF, when I touch the screen it turns back ON so I guess it's working. I'm using the fdt file am335x-boneblack-emmc-overlay.dtb (but I didn't find how to check this really happeing since this parameter are loaded after the auto-boot) I'm loading the module BB-BONE-LCD7-01-00A3.dtbo succesfully So I tried to compare the Xorg.0.log between the opensuse and the debian which is running without issue on the eMMc with the LCD 7" 4D-CAPE-70T (wile using the same xorg.conf) I found several differences: *On debian * II) FBDEV(0): hardware: (video memory: 750kB) *while on opensuse* *II) FBDEV(0): hardware: (video memory: 2250kB)* --> I tried to override this parameter with the parameter *VideoRam 750* in the device section of my xorg.conf but It has no impact* the log is still the same* *On debian I have several built-in extensions* [ 13.488] (==)
