I just installed Fedora 17 in a virtual machine and everything went smooth until I did a yum update and rebooted. Since after a fresh install there were a quite large amount of updates (grabbed the live cd from the fedoraproject front page).
I get the welcome screen, but cannot login with my user anymore, all I get is authentification failure, but I am able to login with the same user in a virtual terminal.
I changed password for my user but still cannot login to gnome.
I created a new user and am able login to gnome-shell with the new one, but it would be interesting to know what ever happened with my first user.
Update: I realize now that I have trouble using sudo as well, even though my user is in the wheel. It worked for a while, now it is authentification failure again.

So, today it is a different story. I am now unable to login to a gnome-shell session, but when trying to use sudo somehow something won't accept my password.
Yet worse is that now I cannot log in to a virtual terminal with my normal user.
I can login as root though.
The only thing I did was to install the system and do an update.
I haven't added any funky repositories or fiddled around in /etc or anything like that.
Just plain installation.
Added first user graphically on first boot, when unable to login with that user I added second user with useradd and finally deleted first user.
I am now on my third user
Hopefully the whole thing will be resolved with an update.
Edit: When writing on this forum the screen was locked in Fedora and I was prompted for my user password.
Did I get in?
