Hi Does anybody know how can I end with my session (gnome in this case) with command line?? Something like logout, with logout doesn't work

You mean end your X session by command line? You can use the very old-fashioned method, and type ctl-alt-backspace. You should, of course, first make sure that no programs are actively running.

Thanks, but what I really need is by comman line. I mean, when I login to my session in the startup a program is running, and when aI end it, it has to be logout when I quit. I hope this is clear now..

I think I'll solve my issue with: sudo /usr/local/bin/killall /usr/bin/Xorg, unless you have anythig else..

I'm not sure why you would do this. Some folks have trepidation about the key combo., but it is a pretty handy and legitimate way to kill the X server. If you really want to do it commandline, then log into a tty: ctrl-alt-F1 find your X process: ps -A and then issue the kill command. This is a rather ugly thing to do though. And, if you're running in init 5, then the X server will most likely restart immediately after you've killed it, though you will no longer be logged in.

you can use gnome-session-save (thats the "official" way).

Is this what you want? http://ubuntuforums.org/showthread.php?t=203240

ed k's suggestion would be your best bet - gnome-session-save --kill --silent Will save your gnome session and log your session out without further interaction Cheers Jim
