+Subject: [greeter] Dont quit when last window closes
+X-Git-Url: http://quickgit.kde.org/?p=kscreenlocker.git&a=commitdiff&h=fae65f1cdd6446042b31ccd0eafd7a4c0b6623e3

+[greeter] Dont quit when last window closes
+
+Qt allows to have no screens. If all XRandR screens are disconnected
+there are also no QScreens. This is from an X11 perspective wrong, but
+we have to deal with it. No QScreens means that all views are destroyed
+and no new ones are created. Thus all windows close and the greeter
+exited successfully which in turn unlocked the screen.
+
+This change ensures that the greeter doesn't exit when all windows close.
+
+Funnily this was not a problem with the well known issue of Qt
+crashing when all screens are disconnected. The lock screen handles
+crashes gracefully and just restarts or more likely Qt also crashes
+the application using KSld and thus taking down the complete session.
