Problème avec Mixxx et DJ Console RMX

Bonjour à tous,

Je suis nouveau sur ce forum et relativement nouveau sur Ubuntu
J'ai un problème avec le logiciel Mixxx et la console RMX. Les deux ont très bien marché quelques temps. Mais sans raisons, Mixxx ne veut plus s'ouvrir en interface graphique et seulement dans le terminal.
Mais je n'arrive pas à sélectionner ma console dans les contrôleurs midi et le logiciel plante au bout de quelques minutes. J'ai essayé de tout désinstaller et de réinstaller, sans succès...
Voici ce qui apparait dans le terminal après lancement de Mixxx.
Merci à ceux qui pourront m'aider
