            Bug ID: 142176
           Summary: No prompt when there's unsaved documents during
                    logout/restart/shutdown
           Product: LibreOffice
           Version: 6.4.7.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
Solution:

Gnome folks say applications should subscribe to Gnome session manager's D-Bus
interface to be able to receive "session close" signal and then act
accordingly.
https://discourse.gnome.org/t/can-ubuntu-prompt-me-to-save-unsaved-documents-during-logout-restart-shutdown/6393

For GTK applications, if "GtkApplication" is used, this is automatic. As Gnome
folks say, there's no generic session management across DEs, and other DEs have
their own implementations for session managing. I'm guessing, using
"GtkApplication" should solve the issue for GTK-based DEs. KDE (and other DEs)
needs separate coverage here. (QT-based DEs may have a common solution for
this. Don't know.)

Steps to Reproduce:
LibreOffice 6.4.7.2
OS: Ubuntu 20.04 Gnome 3.36.8


Setup:
* Autosave is set to 10 minutes (default)

Steps:
1) Open Writer and write something
2) Logout from Gnome session
>> There's no prompt that there are unsaved changes. See Gedit's prompt: https://i.imgur.com/Jpv0O94.png
3) Login to Gnome
4) Open Writer
>> Writer gives the option to recover file
5) Accept Writer's recovering option

Actual Results:
>> File is empty. Data loss. *FAIL*

Expected Results:
Expected: No data loss.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
I think the solution can be implemented in 2 ways.

WAY1:
1) Open Writer and write something
2) Logout from Gnome session
>> LibreOffice gets "session close" signal from DE.
>> LibreOffice prompts the user about unsaved changes as Gedit can do.
3) User handles the rest.
>> No data loss. *SUCCESS*

WAY2:
1) Open Writer and write something
2) Logout from Gnome session
>> LibreOffice gets "session close" signal from DE. LibreOffice saves session. (autosave)
3) Login to Gnome
4) Open Writer
>> Writer gives the option to recover file
5) Accept Writer's recovering option
>> File is recovered. *SUCCESS*
