As a prerequisite to removing Mir's initial black frame, we would want to modify mir-demos to ensure they (the demo servers) actively paint something on start-up. Otherwise you get the situation where you're looking at an old frame (VT?) indefinitely until a client is started. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1672401 Title: Screen is black for too long during login to Unity8 Status in Canonical System Image: Triaged Status in Mir: Triaged Status in Unity System Compositor: Confirmed Status in unity-system-compositor package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Triaged Bug description: This makes me worry there's something gone wrong on every login.

[Touch-packages] [Bug 1672401] Re: Screen is black for too long during login to Unity8
I was thinking about this bug last night. It occurred to me the black screen is probably Mir's mesa-kms driver's first frame that it flips on start-up. As far as Mir is concerned this is a very low-severity issue since the shell should then render a proper frame 16ms later. However since Unity8 is taking several seconds to render a "proper" frame perhaps we need to change the start-up order... Presently: 1. User enters password successfully 2. unity-system-compositor starts and Mir's mesa-kms driver flips a black frame. 3. unity8 starts and Mir's mesa-kms driver flips another black frame that USC probably displays. 4. (several seconds later) unity8 has a proper frame ready and displays that. If we got rid of the dummy black frame from Mir (and we need to anyway since that is us hardcoding a dependency on the GL renderer in the driver) then the best case outcome from that might be several seconds of a frozen login screen before Unity8 appears. I'm not sure that's really any better than blackness. It might be better for Unity8 to take responsibility for this and flip some splash screen immediately on startup for the user to see that everything is OK while it compiles QML and whatever. Also nice would be for USC to display a spinner while Unity8 is not ready (hasn't displayed any frames). However we can't do that right now while Mir is inserting a black frame of its own, which would make USC think Unity8 is immediately ready. ** Also affects: mir Importance: Undecided Status: New ** Changed in: mir Status: New => Triaged ** Changed in: mir Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1672401 Title: Screen is black for too long during login to Unity8 Status in Canonical System Image: Triaged Status in Mir: Triaged Status in Unity System Compositor: Confirmed Status in unity-system-compositor package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Triaged Bug description: This makes me worry there's something gone wrong on every login.

@saviq: I'm not convinced the unity8-greeter should be the "real" login experience for unity8 on classic. When we start shipping u8 as the default we would still want to keep u7 installed as a fallback, but we can't if we install u8-greeter. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1672401 Title: Screen is black for too long during login to Unity8 Status in Canonical System Image: Triaged Status in Unity System Compositor: Confirmed Status in unity-system-compositor package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Triaged Bug description: This makes me worry there's something gone wrong on every login.
