There is a problem with handling the environment if no user is loged into the console. 1. If no user is loged in /etc/profile isn't read. So it is not possible to set some values for example setterm -blank 0 to disable blanking of the console. 2. If I log into my account sworddragon and logout the environment isn't cleared. For example If I set setterm -blank 1 into ~/.profile the screen will still blank after 1 minute if no user is loged into the console.
