In recent versions of Ubuntu, if one of my kids had locked the screen instead of logging out of their account, I could run this command to restart X and get to the login screen:
sudo service lightdm restart
But in 17.10, this command now results in this error message:
Job for lightdm.service failed because the control process exited with error code.
What is the equivalent command in 17.10?
17.10 ditched lightdm and started using gdm
The equivalent to your command would be...
sudo service gdm restart
But ...
sudo pkill -9 -u {user}
would be correct for any Linux system. Users currently present can be shown with the w (/who) command.
But do be careful. I myself would get very angry if someone killed my session when I am not allowed to save my work in progress.
This would send a message to all systems:
notify-send "Ahum!"
It will disappear by itself.
zenity --info --text="Time to go to bed"
would show a popup that needs to be confirmed.
After that you can kill the session ;)
wall message to notify users.
