On my upgraded Fedora 25 system, I encounter a problem when logging in with my main user identity: it takes literally 2-4 minutes to start (i.e. to get me into the gnome shell). Logging in as other users (that basically have not customised their gnome shells), takes only a few seconds.
Disabling gnome extensions does not make a difference.
Logging in as the main user with the gnome x legacy session (x org) takes only a few seconds (as before upgrading).
Sorry, this is not yet a fully formed question. (please help)
One starting question is: which log files (etc) could I investigate?
Another question: what immediate actions could I take to speed wayland starting up?
Cheers!
