SUMMARY

If you say switch user, you can not return to the user you switched away from (without using key shortcuts).
You can only log in and thereby start a second session which most likely will be corrupt or fail as a KDE session for this user already exists.

STEPS TO REPRODUCE
1. Lock screen of user X
2. Choose: Switch user
2. Press: Start new session
3. Try to get back to the user X' session. 

OBSERVED RESULT

You are only presented with the options to start a new session by logging in. Not the option to switch sessions again. This is especially bad, as it seems like logging into your account will do this, but it starts a new session.

EXPECTED RESULT

Option 1: 
Present "Switch session" button in new session view

Option 2: Preferred
Always show all users to choose from, even on lock screen. If that user has already a session, reuse that session, else start a new one for that user.

If this happens, then it's a distro or user config bug, because SDDM now defaults to returning you to your existing session rather than starting a new one. Duplicate sessions are pretty janky and don't really work properly. :(

I found the "ReuseSession" setting in the /etc/sddm.conf [User] section and set it to true. 

Now duplicated sessions are not happening anymore.

But I do get thrown back to the "New session" dialog instead of getting int the running session. So still stuck without using key shortcuts.

Any idea what I can configure? My manjaro is up to date, but it was installed a long time ago. So maybe the config is not up to date.

Hmm, that seems like our fault. Thanks for checking.

This was fixed a while ago.
