After preupgraded to F16_x86 from working F15_x86 system i cant use X server gnome3 and login screen not working..Before the preupgrade process i looked common bugs section and saw the virtualbox repo bug and manually disabled from gui then started upgrade process all went normal without errors.Installed latest kmod-nvidia drivers for my 8500gt nvidia card using
default xorg.conf by xconfig.When booting i can see nvidia logo and screen starts blink 3-4 times in dark screen then stop freezed fedora loading bar.After that i checked virtualbox repo not disabled and removed all the thirdparty repos manually.Re-installed gdm gconf gnome-desktop i did distro cleanup, cleaned dupes orphans also did distro-sync not helped still cant see login manager gnome not working..i saw someone fixed this via `dconf update` command but when i try that it gives error cant write to file in db..etc i need to recover this situation.

Sorry it's taken so long to get you an answer, but I'd not noticed your question before for some reason. I'd had the same issue, and as it turned out, gdm was looking for a missing database. Use ^Alt-F2 to get to a text console and log in as root. Then, run this command:

yum reinstall gdm

After you're done, reboot and it should work. Good luck and, again, sorry for the delay.
