Bonsoir,
Après avoir récupéré ce soir mon ordinateur oublié hier chez un proche, lors de l'ouverture de session sous Kubuntu 17.10 les icônes du Bureau s'affichent, ainsi que le fond d'écran quelques secondes, avant de disparaître pour laisser la place à un écran noir. Je suis tombé en faisant quelques recherches sur le "KDE Black Screen of Death" ...
Je précise "oublié chez un proche" car je ne me rappelle plus si je l'avais éteint ou pas avant de partir, bien qu'il me semble que je l'avais mis en veille. Mais pas sûr, en tout cas le câble d'alimentation était débranché.
Mon tableau de bord, quant à lui (appelé "dock" dans le titre pour des raisons de place mais il s'agit d'une personnalisation du tableau de bord par défaut), n'apparaît pas du tout est je n'arrive pas à l'afficher. Je précise qu'il est configuré pour se masquer automatiquement.
D'après mon observation/utilisation de KSysGuard le bug vient de plasmashell.
Voici ce que j'obtiens en essayant de le lancer :
:~$ plasmashell
