Minecraft Has Crashed (linux)

Bonjour,
j'ai chercher sur ce site pour une réponse à ma question. Mais j'ai pas trouvé une qui marchait donc je vous le demande à vous. Quand j'ouvre mon minecraft sur mon ordinateur portable je suis capable de me connecter sans probleme mais après avoir téléchargez tout les packages mon écran devient noir et après bleu et ceci m'apparait. Sur mon autre PC avec Linux il marche très bien et avant minecraft marchait aussi sur moin portable mais maintenant voila ce qui m'affiche.. Merci de me répondre dans les plus court delais.
