La lumière LED de ma souris m'énerve lorsque je dors. Je ferme généralement mon ordinateur portable le soir et les appels Ubuntu pm-suspend
. Quoi qu'il en soit, la prise USB est toujours alimentée. Je pourrais même recharger mon smartphone. C'est mauvais pour moi pour deux raisons. Je dois débrancher ma souris et la batterie de l'ordinateur portable [akku] dure moins. Existe-t-il un moyen d'éteindre automatiquement mon périphérique USB, ou tous les périphériques USB, lorsque l'ordinateur portable passe en mode suspension?
Comment le configurer?
EDIT: Comme demandé dans les commentaires, j'ajoute ces informations: J'utilise un Lenovo G550.
