I have problem because my friends with I live often forget to shut down our computer.
I don't know how solution use to pretend it. There is ubuntu system installed.

I am looking for solution that user will be force to click and confirm (once a hour) that someone uses computer. If he doesn't it computer automatically should do shutdown.

Is there any solution for this problem ?

That's a working script of what you want to do:

#!/bin/bash

while true; do

   sleep 59m

   zenity --question --text "Are you using the pc (click anything)?"&

   zenity_id=$!

   #the user has 1 minute to answer, otherwise PC will shut down

   sleep 1m

   if kill $zenity_id 2> /dev/null; then 

      #zenity was still running, shutdown the pc

      dbus-send --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown

   fi

done

Every once an hour it displays a pop-up asking 'Are you still here?', if the user clicks on something, then it doesn't shutdown for another one hour (in one hour the pop-up is shown again), but if more than 1 minute passes without interaction with the dialog, then the PC automatically shuts down.
In order to start this on startup, create a file with the above code and make it executable (right click->properties->permissions->allow executing file as program) and click on the power button to the top right of your screen, select startup applications and add this script.
