@memeka i'm in a strange situation. es works. i don't know why.
friday, i made some tests, in es, i made some tests and it finally, things were like if it worked except that nothing were displayed on the screen except the square via testgles2 (es launched, normal output, ... some error about textures however).
then, the week end. i've been unlucky all the week end for my home, and i've worked all the week end to resolve my problems - no time for batocera.
finally, tonight, the chance turned. i've started my xu4, touched nothing, es appears, kernel 4.14, fps 30fps. it seems that is works. i first thought that it was the bad sd card.
the only problem is that i don't know why. i think that for an unknown reason, friday, i had just to restart to make it work.
i've to add some emulators and be able to rebuild all that ; but it's on the good way.
