Comment 29 for bug 36251

I have had this problem of unreadably tiny username and password font sizes on Feisty and Gutsy, and now on Hardy. My system uses a 50" DLP TV as its monitor. No multiple monitors, or anything fancy, just my TV connected via a VGA cable. I would like to try setting the font size as mentioned above where the HumanCircle.xml was modified. But - where is this file located? I'm using a different login screen, so I figure I need to modify the .xml file for the login screen I'm using, rather than the Human circle one, but first I gotta find it. Can someone please enlighten me as to where these files are located?
