Title:
Trusted prompt sessions get stuck on screen blank
Status in “unity8” package in Ubuntu:
Triaged
Bug description:
When a trusted prompt session is open on top of the dash, and the
screen is blanked (either via timeout or pressing the power button to
turn it off), the app which is running in the prompt session
disappears upon turning the screen back on. In some cases, this leaves
the dash in a state where the user is unable to interact with it, and
the only recourse is to reboot or run "restart unity8-dash" if the
Terminal or an adb shell are available. In some cases, this also
leaves the app which was in the trusted prompt session, running in the
background, and it will not get terminated by the system.
To reproduce:
1: Go to the YouTube scope.
2: Scroll to the bottom of the results and tap the "Log-in to YouTube" result entry.
3: When the online-accounts-ui opens up, turn the screen off.
4: Turn the screen back on and notice the login window for YouTube is gone, and the dash cannot be interacted with.
So far, I've only been able to do this in the dash, either with the
YouTube log-in, or with the app purchasing flow (which is slightly
more complex to test).
When reproducing this in ubuntu-system-settings-online-accounts, the
new account login window goes away, but it is still possible to
interact with the system-settings UI, so the user can recover by
trying to add the account again, or just quitting system settings.
