Bug 2438910

Description of problem:
There is a race condition, which sometimes make F44 Workstation Live boot into a "frozen" state. I saw it on both bare metal in a VM. Petr Sklenar confirmed this as well.

In the frozen state, I see the GNOME desktop and the welcome dialog (run installer/not now). It's in "full desktop view", which is weird, because on a normal startup it's in "gnome overview" state (you can see the bottom dash, etc). In this state, mouse cursor can be moved, and gnome itself updates (e.g. an power adapter icon when un/plugging adapter, but no input is handled. Mouse button events do nothing, keyboard events do nothing.

It's possible to switch to TTY3 using Ctrl+Alt+F3. But the login prompt never appears, just a blinking line. 

It's also possible to switch to TTY1 where GDM lives, and input works there.

After returning to TTY2 where the  live desktop is, it's still frozen, but less frozen. Regular keyboard events start working - I can navigate the welcome dialog and anaconda using keyboard only. But mouse buttons still don't work, and no gnome-shell actions work (no overview, etc) - even including keyboard! So no Win key, not Alt+Tab, etc.

I tried adding systemd.debug_shell to kernel cmdline, so that I can gather logs in the frozen state, but unfortunately so far it always booted just fine with this extra argument.

Currently I have a suspicion that either this is a gnome-shell/mutter problem, or that it is a systemd problem with some services hanging (or similar), because it's very suspicious that even login prompts in text TTYs don't show up...
