The filename > .xsession-errors is defined in the script file /etc/X11/Xsession Interesting, but there seems to be more to the story than this. I use xfce4 with lightdm, and I also have my .xsession-errors moved to .xsession-errors.old when I log in via lightdm, even though I'm not using lxde and lxsession doesn't exist on my system. I haven't tried the audit method to see what's doing it. Celejar
