So no, Onboard isn't the cause. The unlock dialog's buttons still lock
up when Onboard isn't embedded into the screensaver.
The ultimate cause most likely lies within gnome-screensaver itself,
there is a lot of pointer grabbing going on during normal operation.
However, the trigger seems to be the way indicator-session locks the
screen. I can reproduce the lockups pretty reliably, on desktop and
Nexus 7, with:
dbus-send --type=method_call --dest=org.gnome.ScreenSaver
/org/gnome/ScreenSaver org.gnome.ScreenSaver.Lock; dbus-send
--type=method_call --dest=org.gnome.ScreenSaver /org/gnome ScreenSaver
org.gnome.ScreenSaver.SimulateUserActivity
They seem to disappear with adding a one second delay between those
calls:
dbus-send --type=method_call --dest=org.gnome.ScreenSaver
/org/gnome/ScreenSaver org.gnome.ScreenSaver.Lock; sleep 1; dbus-send
--type=method_call --dest=org.gnome.ScreenSaver /org/gnome ScreenSaver
org.gnome.ScreenSaver.SimulateUserActivity
I'll link them both for now, gnome-screensaver and indicator-session.
They'll be better able to sort this out.
