After upgrading from fedora 24 to 25 on a mbp mid 2010, i had the gray
screen with nothing happening. Pressed enter, enter my password and the
fedora wallpaper appeared. I found out that fedora thinks that my screen is
a secondary screen. Mirrored the screen and everything is back to "normal".
I am guessing that since the computer has two GPUs, it selects one as a
primary screen and the other one as a connected display port.
Whenever i restart, i need to login without seeing the login screen but
when my session loads, everything is ok. No external screen should be
activated when login in.
This is my first contribution to the linux community so let me know if i
did not follow the usual procedure.
Thanks
