[RÉSOLU](BUG) Bascule entre session aléatoire

Bonjour à toutes & à tous,

Cubuntu 14.04x64 nouvellement installé avec la v171c, 4 profils utilisateurs.
La commande "Se déconnecter" via le menu principal ou CTRL-ALT-SUP fonctionne quand ça veut...c'est à dire qu'il faut répéter l'opération plusieurs fois pour enfin sortir de la session...
Petite précision, c'est toujours pour basculer vers une autre session et non pour la fermer.

Je prends le risque de mélanger un autre problème à ce post mais je soupçonne un lien: lors d'une bascule réussie vers une autre session déjà ouverte, le lancement d'une application se solde par son apparition dans le tableau de bord avec, à droite du libellé de l'application lancée une icône représentant le sablier (rond dentelé) sans animation et c'est tout...Après, c'est le shangaï total, plus rien ne fonctionne dans cette session, obligé, quand ça veut bien, de réinitialiser le serveur X.

Rien dans les fichiers log pour me donner une piste...

Dans quelques heures tu auras la mise à jour en Cinnamon 2.2.13 tu pourras essayer, voir si ça corrige ton problème.

Merci ek0892,

J'espère que cette mise à jour va corriger le problème car depuis mon dernier message, j'ai fait d'autre tests et du coup, j'ai pu vérifier que le problème est récurent et systématique.

La mise à jour n'a rien changée...
Si j'ai bien compris le cheminement du problème, cela commence dès lors que le timer d'extinction de l'écran se met en route.
J'avais déjà désactivé l'économiseur d'écran, celui qui affiche son fond d'écran estompé avec l'heure en grand, car j'avais remarqué que de retour dans une session verrouillé, je n’atterrissais pas directement sur le bureau mais sur l'économiseur.
En attendant une solution, je vais tester la désactivation de la gestion d'énergie, éteindre l'écran manuellement et voir si cela change quelque chose...

sudo gedit /etc/xdg/autostart/indicator-session.desktop

retire : NotshowIn=X-Cinnamon;


et dans :

sudo gedit /etc/xdg/autostart/indicator-power.desktop

Merci ek0892 de te pencher sur le problème, j'en ai assez de me faire enguirlander par la famille...

Je n'ai pas encore tester ta solution, étant sur un autre poste mais par curiosité, j'ai jeté un œil dans les fichiers cités et nul trace de la ligne:
NotshowIn=X-Cinnamon;

Ceci dit, cette machine a été installée avant la sortie officielle et même si je la tient à jour avec ton script, il se peut qu'il ait des différences...

En attendant de retourner sur le pc incriminé, j'ai cherché et trouvé quelque chose dans .xsession-errors qui pourrait être une piste pour quelqu'un qui comprend son contenu...

J'ai du faire trois fois la demande avant de pouvoir basculer vers une autre session et j'avais pris soin d'effacer ledit fichier avant le test (Dommage que ce log [et d'autres] ne soit pas horodaté / PS: Au fait, et le kern.log vide ? ).

J'ai modifié les fichiers cibles, ils contenaient bien la fameuse ligne.
Tests en cours...

Mauvaise nouvelle...Il faut toujours s'y prendre à 2 ou 3 fois pour basculer vers une autre session...

Bon, les symptômes sont toujours présents :
Il faut s'y prendre à plusieurs fois pour basculer entre session
Après un certain temps, revenir dans une session permet de basculer et travailler avec les applications déjà ouvertes mais tenter d'en ouvrir une nouvelle se solde par son affichage dans le tableau de bord avec le sablier à droite du libellé et c'est le dahoua total...

Toujours la même chose, entrer, travailler, sortir d'une session dans un court délai : pas de problème.
Laisser sa session ouverte mais verrouillé, idem si ce n'est pas pour très longtemps.
Mais dépassé un délai, c'est du grand n'importe quoi.
J'avais bien vu une fenêtre apparaître/disparaître en retournant dans une session déjà ouverte; il s'agit de la boîte de dialogue de déconnexion...
Je continue à penser que tous ces problèmes sont liés aux messages d'erreurs que l'on trouve dans .xsession-errors :

Détail: mon /tmp est logé en ram via tmpfs ( /etc/fstab: tmpfs /tmp tmpfs mode=1777 0 0 )

Alors quoi ? On en reste là ?
Je ne voudrais pas paraître désagréable mais les responsables de la distro se doivent de répondre au problème que j'ai évoqué plus haut.
Il n'a rien d’anecdotique, si c'est une distro mono-session, alors que ce soit dit haut et fort !
Ce n'est pas comme ça que l'on va installer chez madame Michue une distro gnu/linux à la place de w$ ou convaincre un fanboy d'apple que sa vie privée sera mieux protégée en passant du bon côté de la force.

Certes, je suis un peu remonté car j'ai investi dans une nouvelle CM, un i5/HD4000, 8Go ram et un ssd de 120Go pour y installer la distro la plus sympa à ce jour (c'est mon avis et je le partage) pour finalement me retrouver avec un veau à trois pattes.

En plus de ce problème de session instable, je vois dans le tableau de bord, à chaque lancement d'application, une icône dentelé à droite du libellé de l'application en cours de chargement et ça, ça signifie qu'une seule chose : quelque chose cloche et ralenti le système.
J'en suis d'autant plus sûr que, comme par un heureux hasard, j'ai vu pour la première fois cette fameuse roue dentelé au lancement d'une application sur ma machine principale qui est un vieux coucou mais dans des circonstances différentes: je suis en train de tester un programme hautement multi-thread ( ~700 ).

Merci d'avance aux mainteneurs de se pencher sur ce problème qui j'en suis sûr ne doit pas impacter que ma machine.

bonsoir, désolé non je n'ai pas constaté se problème

Ce serait vraiment sympa de se pencher sur mon problème...  

Afin de ne pas perdre le bureau Cinnamon, je suis passé sous Linux Mint et tous mes problèmes liés à cet environnement ont disparus !!!

Le fait que le bureau Cinnamon soit destiné/développé à la base pour Linux Mint, il semble logique qu'il fonctionne parfaitement sur la distro d'origine.

Ce passage par Cubuntu aura eu le mérite de me faire connaître/apprécier le bureau Cinnamon.
