This does not require any design work: it is already in the spec <https://wiki.ubuntu.com/SessionHandling#Lock> and it is already implemented.
If it's not happening for you, it is a bug. Can you be more specific about which version of Ubuntu you're using, and what your "Lock when idle" setting is? ** Project changed: unity8 => unity8 (Ubuntu) ** Changed in: unity8 (Ubuntu) Status: New => Incomplete ** No longer affects: ubuntu-ux -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1477419 Title: [Unity][Phone] Dim screen incrementaly after specific time instead of turn off screen immadiately Status in unity8 package in Ubuntu: Incomplete Bug description: For Desktop, after some time (10 minutes), the screen is locked. It is made with incremental dim. It is very useful, when user is reading article and there is no input from keyboard and mouse With that feature he notice that soon screen will be locked. It will be great to implement incremental dim also for Phone Currently: After specific time of user inactivity, the screen is turned off immediately and the phone is locked immediately. Proposal: After specific time of user inactivity, the screen is dim incrementally. User have 3 seconds to touch screen and prevent from screen locking. After 3 seconds pass, the screen is locked and screen is turned off. Rationale: During reading on phone, most ofter user is not touching screen. It cause screen locking immediately, which interrupt reading. Proposed solution allows user to prevent from screen locking and continue reading.
