Bon bah voilà :
Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller
Mais le monsieur demandé :
j aimerais juste savoir comment faire pour savoir si les drivers de la carte graphique sont bien installer
Pour ça tape ou copie/colle simplement :
glxinfo | grep direct
Si tu vois Yes en face de direct rendering cela veut dire que l'acceleration matériel est activé.
Bizarre qu'avec la commande lspci il n'a pas la ligne VGA compatible controller:Intel................etc........
et que ça apparaisse avec l'option -v, non ?

Edit : Je pense qu'il n'avait pas dû poster tout le résultat de la commande lspci ...!!!😉
Alors le pilote est là (même étonnement...), normalement cela devrait être bon.

Désactive le défilement doux dans firefox. Après le pilote intel évolue en ce moment, donc cela devrais s'améliorer petit à petit...
merci de vos réponses pour le premier j ai tous copier , dsl du retard j étais occuper
