= Problem =
You try to login to your graphical environment under linux, but the screen remains black and nothing more happens.

= Solution =
It does not matter if you have a vanilla (brand new) account (without any profile folders) or an account with an old KDE/Plasma profile in it. In Debian Stretch (and maybe also in Debian Buster) there is a bug which prevents the proper first start of Plasma. To circumvent this problem you have to stop the current session and then login again.

 * Press {{{CTRL-ALT-F1}}} to switch to the console.
 * Login with your credentials
 * use {{{loginctl list-sessions}}} to check the running sessions. If you have just login through Plasma and have opened a console you should see two sessions. The session under tty1 is the console one, the other one is the Plasma Session:
 {{{
$ loginctl list-sessions
   SESSION        UID USER             SEAT             TTY             
         3      16320 username         seat0                            
        49      16320 username         seat0            /dev/tty1       

2 sessions listed.
}}}
 * Now you can kill the hanging session (in the above example the first one with SESSION ID 3) with {{{loginctl terminate-session 3}}}
 * After the Login Manager has restored, login again.
