Re: I solved my problem, see below.
Hello,
Simple thing: how I can control the locking screen? On my fresh Mageia-7 install, the screen is locking in few minutes of inactivity, 2 min may be. I need to enter my username and password every time to unlock the screen. Very annoying! It is fresh install Mageia-7 plasma with all default parameters. I just upgrade the system via Control Center. I spent already several days looking for solution, no luck at all. It seems to me that "7" is less responsive than "4", which I had before. So, in general - I am not impressed with "7".
