I have the same issue using the nvidia driver.

Comment 2 Greg` 2011-09-29 06:50:49 EDT
i get the same problem , just that i can log into XFCE and KDE, just not Gnome
Comment 3 Steve 2011-09-30 02:30:19 EDT
This bug is not fixed in gdm-3.2.0-1.fc16. Same error, can't login to gnome.
Comment 4 Greg` 2011-09-30 03:05:35 EDT
still not fixed for me either . ( just did the Gnome 3.2.0 update )
Comment 5 Adam Williamson 2011-09-30 14:47:52 EDT
I don't think this has anything to do with DRM or the graphics driver, I think it's more likely simply a bug in gdm.

Can you set Enable=true in the [debug] section of /etc/gdm/custom.conf try to log in, reproduce, then attach /var/log/gdm/\:0-greeter.log and /var/log/gdm/\:0-slave.log ? Thanks!

There is no way to log-in because there is no log-in-dialogue (See the picture in Comment 0).

I have installed 16-Beta.RC4 (29-Sep-2011) and gdm is working fine. Can someone confirm this?
