Can you please make new "broken" log files as follows: Rerun the gconftool command as your user, but now with "true" at the end. When you log in again, it should be broken. Switch to a console with ctrl-alt-F1 and log in and run:
xrandr --verbose -d :0 > xrandr.broken.txt
cp /var/log/Xorg.0.log Xorg.0.log.broken.txt
Now you can run gconftool with "false" to make it work again, and restart gdm with: sudo restart gdm
Make sure you rename back the gnome-settings-daemon.desktop file so that all installed files are like they should be. The "sudo -u gdm ..." command above should make sure you can see the login screen anyway.
