If you want to go down in resolution ctrl+alt++. If you want to go up in resolution ctrl+alt+-.
This might enable virtual desktop. To eliminate that, just nuke the higher resolutions, assuming you want to go down in the first place, from your xorg.conf file. It should be in /etc/X11.
All that kind of bypasses gnome entirely (I've never really used it), and instead messes directly with your X server.
Hope that helps.
