After upgrading from Mageia 8 to 9, I had a few problems most of which I could either solve, hack or live with. But a few moments ago I needed to switch to another user profile and found that it's no more available.
I'm using XFCE, on an x_86 system. The option XFCE offers is: dm-tool switch-to-greeter. Since it does nothing, I tried invoking it from the shell, and I got the following error message:
Not running inside a display manager, XDG_SEAT_PATH not defined
I'm currently using GDM.
I'd really appreciate your valuable input: what should I do? Is there a setting I need to manipulate?
Thanks a million in advance.
