Bug ID: 519945
Summary: Shares not unmounted on KDE logout
Classification: Applications
Product: Smb4k
Version First unspecified
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

DESCRIPTION
Smb4K does not unmount personal CIFS shares when logging out of a KDE Plasma
session, even when “Unmount all personal shares on exit” is enabled.
If I explicitly exit Smb4K from the system tray before logging out, the share
is unmounted correctly. However, if I use the normal KDE Logout action, the
share remains mounted after the user session has ended.
This suggests that Smb4K’s normal exit path performs the unmount correctly, but
the KDE session logout path does not trigger the same cleanup.
STEPS TO REPRODUCE
Log in to KDE Plasma as local user steve.
1. Mount a SMB/CIFS share in Smb4K, for example
//bs-fs01.brownserve.co.uk/steve.brown$.
2. Ensure that “Unmount all personal shares on exit” is enabled in Smb4K.
3. Log out using the normal KDE Logout action, without manually exiting Smb4K
first.
4. Log in as another local user, for example testuser, or otherwise inspect the
mounted filesystems.
5. Check whether the Smb4K share is still mounted under /run/smb4k/steve/... .
OBSERVED RESULT
The share remains mounted after logout.
In my case, the share is still present at:
/run/smb4k/steve/bs-fs01.brownserve.co.uk/steve.brown$
The mount is only removed if I manually right-click the Smb4K tray icon and
choose Exit before logging out.
Relevant findmnt output while mounted:
//bs-fs01.brownserve.co.uk/steve.brown$

Apr 18 00:58:39 wednesday systemd[1]: run-user-1000.mount: Deactivated
successfully.
I do not see the Smb4K share itself being unmounted during logout.
EXPECTED RESULT
When the user logs out of KDE Plasma, Smb4K should unmount personal shares if
“Unmount all personal shares on exit” is enabled.
The mounted share should not remain available under /run/smb4k/<user>/... after
the user session has ended.
