Hi,
This seems still still be confusing a lot of people, I see quite
regularly queries on some forums like G+ that when they upgrade to
anything post F-21 all they get is a black screen on boot. Is there
any way that if way for that to happen automatically where they don't
get to a gdm login prompt?
Well it's supposed to automatically happen if users don't get a GDM
prompt, but there was a case with hybrid hardware where we sending the
prompt to the wrong card.
That was fixed in this bug I think:
