I’m having the following issue: Every time I reboot or shutdown from the Plasma 5 workspace it seems that Plasma “crashes”, I’m suspecting this because I’m redirected to SDDM (instead of shutting down). Also, when this happens my session is not saved.
After this, I see the following error on dmesg:
185.369365] kactivitymanage[1461]: segfault at 7ff42f180d10 ip 00007ff42f3c469a sp 00007ffe3a55a608 error 4 in libQt5Sql.so.5.5.0[7ff42f3af000+3f000]

I’m running openSUSE 42.1 in a Dell Latitude E6440 laptop (Intel 4th generation graphics).
That’s a good idea, any one that you would recommend? GDM? KDM?
Can you provide me some guide/tutorial about installing them?
Also I forgot to mention that, besides the segfault error, sometimes I’m experiencing the following error after reproducing the issue (sounds Intel graphics related):

In KDE4 there was a switch you set to save sessions I assume the same in Plasma 5 Should be some where in configure desktop?
Probably need to. Keep one problem per report and and give the best description you can but no long stories keep it short and to the point. Oh and check to see if any other has made a report first and just add to that one if found
You can submit a bug report if you want to, but please do so upstream at http://bugs.kde.org/.
Although the kscreen crash might be related to the graphics driver too, and the kactivitymanager crash is known I think and might already be fixed even in 5.16.0 (to be released tomorrow).
PD: Also, trying to debug this made me realize that Plasma 5 is not saving my session, is this normal?
It does save your session (by default at least, you can configure that in “Configure Desktop”->Startup and Shutdown->Session Management).
But at the moment there are still problems with Qt5/KF5 based applications in this regard. They are randomly not restored on login (seems to be a timing issue/race condition).
According to what I was able to figure out so far, they seem to be crashing when saving their state on logout because their window is already closed at that point, and are therefore not regarded as running on logout by the session management.
Other applications (including KDE4 ones) should be saved/restored correctly and reliably.
A possible workaround would be to set the session management settings to “Start with a saved session” and store the session manually before logging out (in the application menu under “Powermanagement/Session”). This should work correctly even with KF5 applications.
