Comment 0 for bug 1730229

The desktop area stops accepting inputs from the mouse, keyboard, trackpad, and touchscreen.
I can move the pointer using the trackpad or attached mouse, but clicking or typing has no effect.
However, gnome session is not frozen, because I can still interact with the topbar and the Ubuntu Dock.

What I can not do:
- I can not close windows using the window buttons.
- I can not move windows.
- I can not bring windows to the foreground.
- I can not click on any dialog buttons.
- I can not type in any test areas (such as in gedit).

What I can do:
- I can start the activities view by clicking on Activities in the top left corner.
- I can launch programs from the dock and from the applications button.
- I can also interact with the notifications area or the indicator icons at the right of the topbar.
- I can type and search for applications after entering the Activities overview.

Logging-out and loggin-in does not resolve the problem.
- Note that GDM accepts mouse and keyboard inputs.
- After logging back into the desktop, I can not interact with the desktop area, as before.

Restating is the only way to regain ability to interact with the windows and desktop area.

I'm not sure if mutter is responsible for handling mouse/keyboard inputs separately from GDM, extensions, and the topbar, so I opened this bug against gnome-shell.
