Hello anyone that can continue and help me on this same issue. I applied all that I learned from this thread to my Fedora 25, and I can establish a session only when I am not login to my Fedora.
Right now I am using my Windows 7 to connect to my remote Fedora 25. I can see the session, I can see my login information, but as soon as I enter my password and Fedora starts to login, I got a black screen. Also, using the little gear next to my "sign in" button, I select GNOME on Xorg, but that did not help.
Is there any thing someone could guide me to solve this?
