My understanding is that VT switching only works on the console display,
and not on multiple attached displays.  Did VT switching on multiple
displays ever work for you with the old GDM, or in any other
configuration?

Regarding your issue with a session accepting keystrokes from multiple
keyboards and audio device permissions.  Note that different distros
manage device allocation and permissions differently, and the Xserver
configuration also plays a role in how this works.  So, these sorts of
problems may not be closely related to GDM.

The new GDM always shows the "Login" button.  There is currently no way
to configure it to not show that button.  Also, the new GDM does not
currently provide any configuration options to disable sound.

The GDM Init script gets run before displaying the GUI, so if Fedora
provides CLI to turn off sound, you could run it from there.
