I think that's because this was considered mainly as a visual design problem: "these two screens look roughly the same, let's make them exactly the same". But they behave very differently: music should keep playing at the lock screen but not the greeter, the camera and mic should keep recording at the lock screen but not the greeter, Touch apps may allow limited access at the lock screen but not the greeter, your preferred keyboard layout should persist at the lock screen but not the greeter, screen magnification should persist at the lock screen but not the greeter, and so on. Things that behave different should look different, which leads to the conclusion that the lock screen shouldn't look like the greeter after all. (This reminds me of the logic "snap decision dialogs look roughly like notification bubbles, let's implement them in the notification system", which has led to similar poor containment, e.g. Unity8 having to contain knowledge about the format of SIM PINs.) - -- mpt -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlMZodsACgkQ6PUxNfU6eco2MwCgqXka223UGmasgrFZYLqYnwtR 2IMAoKzEHt30qCNneCvQigng2kfCWgjD =BCKY -----END PGP SIGNATURE----- -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : ubuntu-phone@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
