Hi again Fritz,
When you log out of XFCE it should kill all running processes except for
things like NetworkManager.
If you want to kill a process like compton
pkill compton

if it is a root process you need
sudo pkill /<process>/

If you want to stop a service like network manager or lightdm
sudo stop network-manager

So, if you get in a bind in your window manager drop to a TTY
log in
sudo stop lightdm
sudo start lightdm

sudo restart lightdm

this will bring you back to the lightdm login screen (or log you into
your default session if you auto log in)

In other words the OGs from compton stay in their hood while the OGs
from XFCE stay in theirs... and things can get messed up if you try to
bring compton to XFCE.
