Penumbra loads, but screen goes blank.

You don't have a settings.cfg file because it is created on exit of the game, so as it crashes on load it does not get that far. You should normally not do this, but in this case you can go to installation directory/Penumbra/config/ and find a default_settings.cfg file that you can open and edit as suggested above. To be on the save side, save a backup copy of the original default_settings.cfg first as it is this file that is later used as a base for new user settings.cfg files.
