A sessão do KDE não pode iniciar no kubuntu 15.10 [duplicado]

0

Eu corro um laptop Asus no kubuntu 15.10. Ele tem funcionado bem (exceto que o tempo de inicialização foi muito longo sem nenhuma explicação clara) e, desde ontem, eu não consigo mais iniciar uma sessão do kde. Eu entro no meu login e senha, e depois de alguns segundos, eu sou enviado de volta para a tela de login.

Aqui está um rastreamento no syslog:

Eu também posso ver outra mensagem de log, mas não sei se é relevante:

Alguém pode me ajudar a corrigir meu problema?

Obrigado pelo seu comentário: a causa raiz é de fato a mesma. O arquivo .Xauthority era de propriedade do root, e eu tive que mudar o proprietário para resolver meu problema.

Com mais detalhes, realizei: usuário chown: group ~ / .Xauthority onde user é meu nome de usuário e agrupar meu grupo padrão
