I had a curiosity about this, because some people are reporting that they need to manage their growing .xsession-errors file by various methods, but I never have seen this. I see the same behaviour as Andrei, and I also use parts of LXDE. I investigated, guided by this teaching from Reco: https://lists.debian.org/debian-user/2020/04/msg00583.html I found that the process that renames the file to .xsession-errors.old is the binary /usr/bin/lxsession owned by the user, with the parent process lightdm owned by root. /usr/bin/lxsession is a component of LXDE, so this won't apply to users of other GUI providers. The rename occurs when the user logs in from lightdm. The filename .xsession-errors is defined in the script file /etc/X11/Xsession
