I'd say we go for the simplest solution +++ Given we have MPRIS on here, if we were to do any DBus lockdowns we would almost certainly want to use xdg-dbus-proxy, at which point this would continue to work.

DBus receiving is in another thread so you could hypothetically get a message between the two events. Doesn't really matter if we lose a notification in this case, but it's a good practice > greeterapp.cpp:497 > + // we invoke the notify method of the greeter root object > + QMetaObject::invokeMethod(rootObject, "Notify", Qt::QueuedConnection, > + Q_ARG(uint, id), This pattern of fetching and poking the root object of a scene isn't one I like, it's better to expose an object to the view that then has normal signals and slots - but this does follow the convention already here, so I can't really object. > greeterapp.h:51 > Q_OBJECT > + Q_CLASSINFO("D-Bus Interface", "org.kde.screensaver.GreeterApp") > public: You don't need this if you're using an adaptor REPOSITORY R133 KScreenLocker REVISION DETAIL https://phabricator.kde.org/D28455 To: bshah Cc: davidedmundson, plasma-devel, Orage, LeGast00n, The-Feren-OS-Dev, cblack, jraleigh, zachus, fbampaloukas, GB_2, ragreen, ZrenBot, ngraham, himcesjf, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, ahiemstra, mart
