J'ai mon vieux PC portable Dell Inspiron 6000 qui est équipé d'un chips Intel 915GM Express Graphics Controller (le CPU est un Celeron mobile, basé sur un Pentium III)
L'écran LCD 15 pouces intégré est connecté via une interface LVDS.
J'arrive à démarrer Ubuntu 16.04 et Lubuntu 16.04 depuis une clé USB, l'interface graphique se charge bien.
Une fois installé, Lubuntu xORG refuse de se charger.
