# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minim 800x600, current 800x600, maximum 800x600
default connected primary 800x600+0+0 0mm x 0mm
800x600 75.00'
# xrandr -s 1920*1080
Size 1920*1080 not found in available modes
Est-il possible de "lancer manuellement" la fonction KMS une fois que
l'on a démarré avec i915.modesetting=0 ?
