I hope that the startup time of a shell get's better with PW2 - especially being able to delay loading of elements through a QML LoaderItem and better threading should improve the situation. Nevertheless it has to be a design goal to have more or less instant locking. If the widgets are not loaded I don't care as long as there is at least the background item loaded. > > something else we'll run into: > > the unlock greeter needs to be ported to QML properly. right now and > GreeterItem and KeyboardItem use QGraphicsProxyWidgets and this will break > in QML2 w/scenegraph. that means kxkb needs to provide a proper QML > component and the kgreet plugins in libs/kdm/ will need to turned into QML > bits. the complication there is that kdm uses them as well ... so maybe > some library duplication there, or .. we look at alternatives to kdm. Back when I started to work on this I run into this issue. The keyboard item should not be that difficult but the kgreet plugin will be a nightmare. The complete logic is implemented inside a QWidget. The individual greeters just add further widgets to the base widgets. My fear is that we have to start from a blank sheet of paper and given that it is security related I must say that I don't like it. I'm not sure whether we have any experts on security in the workspaces team? Random thought: we might have a look on whether we can do some re-usage of LightDM greeter bits. Maybe that's easier - David might give input on that.
