I have two users and can't switch from one to the other, regardless of whether I'm using gdm or lightdm.

The only thing that works is logging out and logging back in with the other user; I think I can start only one session.

What could be the problem?

There was a problem with the nvidia-340 driver. I switched back to nouveau and now all is working fine.

There is a question about disabling user switching. The answers describe several settings to disable the feature but you can use the information to check and re-enable user switching.
