I find this part most interesting:

     ├─2*[lightdm─┬─Xorg]
     │            ├─lightdm─┬─lxsession─┬─caja───3*[{caja}]]
     │            │         │           ├─claws-mail───{claws-mail}]
     │            │         │           ├─clipit]
     │            │         │           ├─lxpanel]
     │            │         │           ├─openbox]
     │            │         │           ├─pcmanfm]
     │            │         │           ├─ssh-agent]
     │            │         │           ├─zim]
     │            │         │           └─{lxsession}]
     │            │         └─{lightdm}]
     │            ├─lightdm]
     │            └─2*[{lightdm}]]

There is a whole lot of programs still running -- check the lxsession
subtree: An openbox (which is a window manager) is still running and
some other LXDE stuff as well (pcmanfm, lxpanel), also a mail client. To
kill the last window manager just terminate "openbox" via killall
openbox. However, it might be required to terminate the whole tree,
probably something like killall -s TERM lxsession or such. On the other
hand, I am unsure how much lxsession belongs to lightdm, i.e. might it
be necessary to keep lightdm running?

Or a script to terminate your session upon logoff.
