Bon, la sortie de :

$ xinput list-props

me dit :

Device 'Elo Serial TouchScreen':
        Device Enabled (117):   1
        Coordinate Transformation Matrix (119): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

        Device Node (243):      "/dev/input/event12"
        Device Product ID (244):        41, 0


Du coup, j'ai ajouté à la config xorg.conf :

       Option "Device" "/dev/input/event12"


et là, j'ai maintenant :

Ça paraît mieux, mais ça n'a rien changé côté pointeur :o/ X est toujours
inversé, et la calibration n'a pas été prise en compte. Je pense que les
paramètres ne sont pas bon ; il faudrait modifier les matrices de
transformation et de coordonnées :

https://wiki.ubuntu.com/X/InputCoordinateTransformation

Mais bon, à la mano, c'est un peu merdique. Y'a pas d'autres outils
capables de générer ces matrices, en pointant des cibles ?
