Système freeze après hibernation

Bonjour,

il semblerait qu'il s'agisse d'un problème récurrent sur Linux. Sur mon notebook, l'hibernation semble fonctionner : l'ordinateur s'éteint et il me suffit de le rallumer. Je parviens à accéder à mon bureau XFCE, et au bout d'une à deux minutes, le système se bloque, s'éteint, se rebloque, avec un dérèglement de l'affichage. Du coup, je suis obligé de retirer la batterie et de le mettre hors-tension. Je n'ai aucune idée d'où vient le problème. J'ai suivi plusieurs tutos sur le net mais sans résultat encourageant.

Auriez-vous des pistes de solutions à proposer ?

Re : Système freeze après hibernation

Bonjour,

Peut-être peux-tu trouver des informations dans les logs ?

Par ailleurs, on doit pouvoir lancer le script d'hibernation depuis un terminal et rediriger d'éventuels messages vers un fichier.

I'd love to change the world
But I don't know what to do
So I'll leave it up to you...

Bonjour,

il semblerait que le fichier syslog n'apporte aucune solution :

Pour information, j'ai enclenché le mode hibernation à 5:58:31 et le blocage est apparu à 6:01:51. Comme vous pouvez le constater, le blocage n'est pas mentionné dans le fichier syslog. Où est le problème alors ?
