Every thing was greate before I updated fedora 15 to fedora 16 using preupgrade command. There's no errors during the update process. But when it's done. I can't log in. No matter how many times I try, I only get an error which shows a sad computer face and says that something is wrong. Does anybody else encounter this problem? Any ideas how to recovery? Thanks!!!

If the first solution does not work for you, other users have reporting a similar issue (the monitor with a sad face appearing after login). However, in this case, the desktop seems to also be somewhat responsive (the meta key brings up the gnome3 overview screen and applications can be launched from there).

SELinux seems to be causing this issue. To check if this issue is what you are hitting, try temporarily disabling SElinux by opening up a terminal and switching to root:

$ su -

then, disable SElinux:

$ setenforce permissive

log out, and log back in to your user account. Hopefully the sad face will not appear for you.

To solve this issue for good, open a terminal and switch to root again. Then run the following command (don't be alarmed if it takes a while to run)

$ restorecon -r /home

the restorecon command restores file(s) default SELinux security contexts, and this seems to solve this issue in this case.

Finally, if you turned it off, don't forget to turn SElinux back on using the command

$ setenforce enforcing

hope this helps!

This could be the reason that your old gnome settings are incompatibility with gnome 3.2 and gnome-shell 3.2. execute following commands as a user.

$mkdir ~/backup $mv ~/.gnome* ~/backup/ $mv ~/.local/share/gnome-shell/extensions/* ~/backup/

then execute following commands as a root,

mkdir /root/backup

mv /usr/share/gnome-shell/extensions/* /root/backup/

then try to login.
