I have installed F7 on a second machine and it went fine. I wanted to use gnome instead of KDE and unchecked the KDE box in the add/remove dialog and checked gnome. Gnome loaded fine but when I reboot it takes me to a gray screen with a diaglog box in the center that says login:
when I use my login and password is just takes me back to this login screen and wont load the desktop.
I have used other logins like "guest" or "gdm" to no avail. what can I type in the login: to get the F7 gnome desktop to load?
