kubuntu 17.04 plasmashell exibe papel de parede, em seguida, deixa de funcionar outras aplicações

Question

Sou novo no kubuntu e uso-o nos últimos meses sem nenhum problema (não causado por mim mesmo) ...

OS é o Ubuntu Linux 17.04 kernel é Linux 4.10.0-38-generic em x86_64

Ontem à noite saí do trabalho e deixei o laptop funcionando; esta manhã eu encontrei plasmashell caiu - eu observei uma tela preta, mas mouse, outros programas, vários desktops, golfinhos, etc - tudo funcionou bem. Apenas sem barra de "menu", sem papel de parede. Reiniciou, logou, viu o papel de parede, depois caiu novamente.

Ran plasmashell de konsole; papel de parede mostra brevemente (como no boot), então vai embora. Aqui está a saída

Eu vejo algumas outras pessoas que tentaram executar o kdeshell como root, criando um novo usuário completo, então tentei ... novo usuário, login - basicamente o mesmo comportamento, mas uma saída ligeiramente diferente (devido a nenhuma personalização) palpite)

finalmente, também vejo algumas pessoas tentando isso como root com sucesso, mas isso também não faz muita diferença - o papel de parede aparece por um momento, depois desaparece, sem menus, sem "bandeja" etc.

Ainda não entendi porque ele parou de funcionar.
