Question

mint

Guys, for the first time I create a user and when I enter the command

useradd -c "ghost" -g users -d /home/ghost -s /usr/bin/plasmashell ghost

the user is created, but it is not possible to work on it, only 4 processes are launched there, and the shell with the queen does not start either. Explain how to do it right?
