-------------------- You are right. I rechecked this and it does not work correctly, because of a bug in KDE. The problem is, when starting another session, your former session is locking. But you can not unlock your session again, even with the correct password. I know about this for more than 3 years and reported the bug long time ago. It is still not fied, but this is not the point here. -------------------- Apart from this, check it. I am running KDE (plasma) and you get the option "change user" from the K-menu. Do this, and you start with the windowmanager you preset in your favourite login manager (I am using lightdm, but sddm or gdm might work as well, too). When both windowmanagers are started, you can click every time to "change user" and then get the option, to chose, to which you want to switch. -------------------- But as I said before: The former one has a locked screen and can not be unlocked. I suppose, this is a rights problem and the locking mechanism is set by root and rooit must unloc it. But as you want to unlock the screen as normal user, it will not work. Maybe sometimes this will be fixed. However, it does not harm the function of starting a second window managers for another user. -------------------- If someone might also confirm of this little bug I mentioned here and knows better than me, he may just file a little bugreport to the developers of KDE. Maybe he also nows a little workaround??? -------------------- Hope this helps and makes things clearer. Best regards Hans
