[SDL] Version: 1.2.13
et le programme ne se lance pas.

enfin kino semble bugger lui aussi (même s'il se lance)

Ces problèmes apparaissent que je sois en user ou en root.
Il n'est pas non plus résolu si je change de driver graphique
(nv ou nvidia).

Voila tout cela est très handicapant, j'espère réussir à trouver le moyen que tout rentre dans l'ordre.
Cela résout effectivement le problème.
Merci de ton aide
