O problema que estou tendo é que depois de logar em GNOME Shell 3.4.1 on Ubuntu 12.04.1 LTS .
Após um curto período de tempo (aprox. 0-2 minutos), a concha de gnomo não responde.
Pairar na esquina / clicar no botão de atividades não faz nada,
Windows ficar preso (o aplicativo está respondendo, mas o gnome não é)
Também o Alt + F2 não faz nada.
A única maneira de saber como resolver esse problema é ir para o Linux shell pressionando + Alt + qualquer de F1 para F6 , faça o login e reinicie o serviço lightdm.
sudo service lightdm restart
Então a questão é: Como resolver o problema de pendurar após o logon no Gnome 3?
