Eu tenho um problema com gnome-shell e gdm. Meu shell às vezes (atm não reproduzível) congela. Em algumas circunstâncias, o gdm será reiniciado e eu sou desconectado e todos os programas são eliminados. Ao fazer login novamente, o chromium, por exemplo, me diz que da última vez não foi encerrado corretamente.

Tentei encontrar algumas informações no dmesg e journalctl, mas não consegui encontrar nada que resulte em uma pesquisa em www que me ajude a resolver esse problema.

O que eu devo fazer a seguir?
