At first reboot, get logging screen with initial user name
Type the password
Get a blank screen with a little windows X type with a message:
"Could not start kdeinit5. Check your installation"
So I stopped Xserver from keyboard.
Got the logging screen
Restart the computer and edit the command line and add "init 3"
Log as initial user.
Then ran startx
.
