My screen resolution, by default, was 800x600 pixels. Today I pressed ctrl+alt+down and, instead of making my screen go upside-down, it just made everything really big. I guess this is a screen resolution problem, but I'm not sure how to fix it. I tried pressing ctrl+alt+up and googled my problem, but it didn't work. I also went to control panel and tried changing the display settings; I'm on 1024x768 pixels right now, but I'd really like to revert to 800x600 sans big chunky display. Please and thanks.
