I log in as the primary user. Then, I try to switch users: I get to the login screen, type in the password, the screen goes black and then comes back to the login screen. I see the input field and the pointer, but the computer is frozen - I can't access a console.
If I reboot, I can log in to a different user, but if then I try to log in to the primary user, the same thing happens.
This only happens when switching between users. If I log out of the current user (end session) I can sign into the second account without any problem.
