For example, if I work as "root" and as "usertest" at the same time and want to logout the "usertest" through the "root" account. I tried logout but it only works for the current user and there is no manual... Any suggestions?
Also: is there any way to disable a user accout temporarily without deleting it, so as the user may not login untill I re-activate their account (without losing the user's data)?
When a process starts, a PID (process id)is spawned. If you give a ps ax it will list all processes running on the system. As root you can kill a process id eg kill ##### (replace the ##### signs with the number corresponsing to the appropriate process id.)
Just to amplify a bit. Linux or Unix treats everything as a file. A disk is a file with certain characteristics. A tape is also just a file. It is the beauty of Unix. It is abstract, but in its own way wonderful.
In order to run Samba creates a process, as does a user logging in, as does kde, gnome etc. When you give a ps ax it will list ALL processes running in the system. Root can kill any of them. If you would like to learn more about the commands you could open a terminal window and issue man kill or man ps. If you are not sure of what command you need, you could try apropos and ???. Replace the ??? with the reference you are looking for. Good luck and welcome to the world of Linux.
Normally? What's a normal login?
Even when a user logs in thru the Graphical Interface, its still using a shell or some sort..
I guess I was not as precise as I should be... I meant that all users in my computer use the KDE graphic login manager and I was wondering if in such a case there are any differences.

To unlock the account
usermod -U username
Thanks, this works great.

Only try this for normal users. For system users, you'll take down half the system in the process.
I tried to use it on a normal user but it fails. There are no error messages and everything seems to work fine, however when I press ctrl+alt+F2 to check if it worked, the user is still there and nothing seems to have changed... The manual was not of great help, what now?
The password lock works fine.

Thank you but I have been using Linux for nearly two years now , although it is the first time I want to be able to use my computer without using the GUI not for a single action. Thanks again.
