1) there was no request of initial password fro root user in initial user, I am sure of it
2) I have to check in my tv-set: I will report it back as soon I will be back home
3) When I shut down I was asked if I wanted to apply pending updates and reboot: I said yes and that's all. All updates were o.k., it seemed only a frozen system
I am using Fedora Workstation with Gnome DE
I have another issue related to keyboard (I am using an Italian Keyboard and it was set as italian): when I write something in the top line of Gnome (when I am looking for application) when I push a character on the keyboard I gent many characters (only in this window, terminal is o.k., i.e I push d and I get ddd)
