Estou tendo um problema com meu KDE 17.04. Ele cai com muita freqüência e não sei por quê. dentro de poucas horas hoje, caiu duas vezes. Às vezes, o teclado funciona, mas o mouse não funciona, e às vezes nada funciona, sem teclado, sem mouse. Alguém está tendo o mesmo problema? Você tem alguma idéia de como resolver ou por onde começar a checar?
Atualizar
Além do fato de que ele trava de tempos em tempos, tudo funciona bem

Assim, após a nossa conversa, é uma atualização para o problema 17.04, que são muitos e os sintomas variam muito, sem correção de 100% para nenhum deles, além de reinstalar. Desculpe.
Siga em frente e siga meu guia aqui: O sistema congela em o log-in sceen após uma atualização do sistema operacional
Eu recomendo usar a opção "formatar / apagar disco e instalar o kubuntu" ou a opção "algo mais" que você não quer que ele tente usar o antigo grub.
