I’m trying Gnome 3.10, and it’s awesome! Perhaps when leave my computer for some time it freezes on the protection screen, where we have a clock and arrows indicating that you can swap to get the login screen.

To restart it you need to get into a terminal:

ctrl + alt + F1, login

so you can kill the frozen process using:

pkill -kill gnome-shell
