Note that after I installed from the alternate CD, while the login screen came up a 1600x1200, the Gnome display came up at 1024x768. Yet when I ran the live CD, the Gnome display initially came up at 1600x1200. Why the difference? After a bit of reflection, I realized that, since I had kept my home directories from the Karmic installation, resolution saved in my home directory (somewhere) would be maintained. BUT I don't know where that is - I'd like to know where the setting from System>Preferences>Display is saved.
