Bonjour,
Je me décide, après quelques mois, à addresser un souci un peu génant sous xubuntu. Pour faire simple, je rencontre de manière aléatoire des "gels" de mon pc 2-3 fois par semaine.
Ces freezes apparaissent de manière aléatoire (rarement successif). En général, l'image reste figé et je ne peux rien faire (CTRL ALT F1 ne fonctionne pas), je m'en sors en général en faisant un ALT SysReq B pour rebooter le pc.
Je ne rencontrais pas ce souci l'année dernière. C'est en revenant des vacances de noël que j'ai eu ce souci de manière fréquente.
A l'époque, j'ai associé ce problème à un changement précipité de noyau (période bug meltdown, spectre). J'ai d'ailleurs constaté au bout de quelques semaines et de changement de noyau de nettes améliorations.
Aujourd'hui ce gel existe toujours bien qu'il n'apparaisse pas très souvent mais cela reste irritant. Je cherche donc à savoir si le souci vient de mon pc ou bien d'autre choses.
Voilà quelques infos concernant le pc, acheté en 2011 et toujours sous xubuntu je n'ai pas eu de souci matériel jusqu'ici.
