I use xdm to log into my xfce session (default session, Xfce 4.10, Debian unstable) and use $HOME/.xsessionrc to start some applications. If I exit/kill those applications after xfce startup, they remain as zombie processes, which wasn't the case with Xfce 4.8. example in my .xsessionrc: command: unclutter & part of pstree: before and after killing unclutter: ├─xdm─┬─Xorg───2*[{Xorg}] │ └─xdm───x-session-manag─┬─Xsession │ └─unclutter ps x after killing unclutter: 13426 ? Z 0:00 [unclutter] <defunct> Thanks, Franky
