I upgraded Ubuntu from 18.10 to 19.04. Shortly after that, GNOME has been hanging.

I started with a 4x4 grid of workspaces. After navigating the workspaces for a little while, the 4x4 grid changes to a 1x16 array. Then, I can't type in any windows, move the windows, navigate between windows, or navigate between workspaces.

I CAN access the command bar at the top. I tried opening Settings. It opens, but I can't interact with anything inside the window or even close it.

Any idea of what's wrong?

    You probably have a bad GNOME extension. Go to extensions.gnome.org/local and temporarily turn them ALL OFF, except Ubuntu AppIndicators and Ubuntu Dock. Restart gnome-shell with alt-f2, r, enter. See if the machine behaves as normal. If so, go back and turn on one extension at a time, testing each one as you go. If it gets a RED error button beside the name, it's not compatible. If it doesn't work as expected, it's not compatible. Report back. – heynnema Jul 9 at 0:32

    Edit your question and show me ls -al ~/.local/share/gnome-shell/extensions and I'll see if I recognize any bad extensions. – heynnema Jul 9 at 0:35
