Bug#931281: gnome-shell: Session cannot be unlocked when audio dialog for plugged in speaker is active

[Paul Menzel]

Package: gnome-shell
Version: 3.30.2-9
Severity: serious

Dear Debian folks,


With Debian Sid/unstable with the default GNOME session, that means 
Wayland is used, logging in and plugging in speakers/headphone a dialog 
pops up if this is a headphone, a headset or a microphone.

If ignore that dialog for whatever reason and go away and your session 
is locked by the “screensaver“, and the screen goes dark. Coming back, 
the session is locked and the dialog is still there. Then you can select 
the corresponding device, and enter the correct password, but your 
session is not restored correctly. The top bar is shown with the menu of 
the last opened application, but the in the background you do *not* see 
the application but still the image of the lock screen. You can still 
switch ttys, but I was unable to get back into message.

In that situation data might get lost, because you cannot save it, and 
have to kill the session.


Kind regards,

Paul
