I am using KDE Neon (last release) that is based upon Ubuntu 18.04, on a Lenovo G50 (8Gb Ram).
When the computer is idle, like when listening to some music, after a certain amount of time (that does not resemble what I decided in the settings) the login screen appears, and it asks for the password.
I see also the "change user" option. If I select such option the system creates a new session for the same user, so it does not lead to the login screen.
I have en encrypted partition so I decided not to be asked for the password, being that I am asked at startup and when coming back after the screen block.
So my question is about three point:
1- If I do not set the password to be asked when logging in does it allow anyone to break my session clicking on "change user"? Are the things related?
2- Is that a bug when "change user" just leads to a new fresh session with the same user without asking me for the password?
3- Where is the lost session?
I think this information could be useful for other people too.
Thanks in advance
