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`
