Bug 955280

When I set up a konsole session in desktop 1 and logout, it is not recreated upon login.  In the directory ~/.config/session, a file, `konsole_10145100a1ea000144831997300000028770008_1448319997_596458' is created which appears to have the proper information to restart the session, however this file does not appear to be read or deleted upon login.

Yes, because it isn't added to ~/.config/ksmserver.

Note that this is only a problem with KF5/Qt5 applications, the session management itself works fine and other applications will be restored.

They seem to crash (randomly, not always) when/after saving their state to ~/.config/session/, so they are not regarded as running any more by the session management and not added to ksmserverrc to be restarted at login.
Apparently they try to access their window, which can already be closed at that time it seems, thus causing the crash. Applications not having a window open in the first place (like kmix running in the system tray), are restored reliably in my experience.

A possible workaround for you could be to set "Start with a previously saved session", and then select "Save session" in the application menu (Session/Powersaving). The manually saved session should work perfectly fine even for KF5 apps (likely because no windows are actually closed at this point).

Apparently they don't crash, they just quit too early and might not be seen by the session management as still running.

I will submit patches pending for upstream inclusion soon (for Leap with Plasma 5.5.4 update, for TW ASAP - first we need qtbase accepted)

Update for openSUSE Leap released.

Resolved fixed, thanks!

Just to be clear here: this Qt update alone won't fix anything. But it's needed for making it possible to fix the problem in the applications.

@Hrvoje: does the Plasma 5.5.4 update really contain anything in this regard?
AFAIK we'd need patches for kxmlgui and kdelibs4support, and separate ones for all applications that don't use the classes from there.

Or am I misunderstanding something here?

Nope; i'll submit latest KF5 (5.19) with needed patches once it's official released.

With the latest patches in KDE:Frameworks5, KF5 applications seem to be saved on logout by ksmserver reliably now, at least the ones I tried so far (konsole, dolphin, kwrite).

But there's still one major (IMHO) problem we should solve (though not really related to this bug report):
plasmashell still quits too early, leaving you without a desktop if the logout is cancelled.
(https://bugs.kde.org/show_bug.cgi?id=349805)

We need a patch there too. I think it should suffice to call sm.setAutoCloseWindowsEnabled(false) in plasmashell's disableSessionManagement function defined in main().
I will give it a try during the weekend...

I cannot confirm that the problem is solved. On my machine, merely 1 dolphin window is restored (but at a wrong location), but the dolphin windows on the other workspaces are forgotten. The terminal window is also forgotten after a logout.

Note that the patches are only in the additional KDE:Frameworks5 repo for now.
Are you using that?

Sorry, that little detail had escaped me. I have been using the standard repositories.

See comment#12.
That's why I reopened this bug report in the first place: it got erroneously closed after the release of the latest Qt5 update which doesn't fix anything yet but is required to be able to add fixes to KF5.

You will get those fixes together with a full KDE Frameworks update to 5.19.0 via the official update repo, but that will still take some time.

If you don't want to wait and/or try it out now, you can add the KDE:Frameworks5 repo and do a full switch to it. You'll always get the latest stable Frameworks and Plasma versions at the day of release then.

Works fine here... ;-)

The update has been released, session saving/restoring should work reliable for KF5 applications now too...

I have installed the update some day ago.

Restoring the session works now correctly.
