+Lightdm (gdm) is the login manager for linux ubuntu and mint (by default)
+
+If you need setup and cleanup that is ONLY done at lightdm login/logout then
+one can run a script to setup and cleanup the session by 
+
+running the loginout-install script, requires sudo
+
+`module_load loginout-install; loginout_install <user>`  # default is current user
+
+after loading common scripts this will ask if you want to add the .session folder for the user
+
+or if you just need to add a user .session folder afterward
+
+`module_load loginout-install; add_user_session <user>` 
+
+
+the script does this
+
+in `/etc/lightdm/lightdm.conf.d`  adds a file `50-setup-cleanup.conf`
+
+```
+[Seat:*]
+session-cleanup-script=/opt/scripts/lightdm-cleanup.sh
+session-setup-script=/opt/scripts/lightdm-setup.sh
+```
+
+in /opt/scripts put two files below and make sure they are +x executable
+
+```
+#!/bin/bash
+#lightdm-setup.sh
+echo "setup for ${USER}:${HOME} $(date)" >> /opt/scripts/lightdm.log
+log=${HOME}/.session.log
+if [[ -e $HOME/.session_login ]]; then su -c "/bin/bash $HOME/.session_login 1>>${log} 2>>${log} || true" $USER; fi
+```
+
+```
+#!/bin/bash
+#lightdm-cleanup.sh
+echo "cleanup for ${USER}:${HOME} $(date)" >> /opt/scripts/lightdm.log
+log=${HOME}/.session.log
+if [[ -e $HOME/.session_logout ]]; then su -c "/bin/bash $HOME/.session_logout 1>>${log} 2>>${log} || true" $USER; fi
+```
+
+then in the user home puts
+`.session_login`  and `.session_logout` files both executable
+in those you can do anything like bindfs and fusermount -u 
+
+make sure you restart lightdm or reboot
+`sdr lightdm`
