Alright, I realize that this is probably a very noobish question, but I've searched for the answer to this question for, like, a whole 15 minutes, and I can't seem to find the answer. (Actually, I've been looking for days).
I've got YDL installed on an old iMac with CRT monitor. Problem: the screen offset. There's about a centimeter of black off to the left of the screen that pushes the whole screen out of center. Sometimes, because of the plastic bezel, I can't even see the "X" button for closing open windows. This problem manifests itself from the yaboot menu (although mac OS X perfectly centers itself).
What file do I have to edit to fix this problem?
