Should XFree86 decouple the display size and the dot pitch then ? The complaints come because fonts are struggling to use the pitch (DPI), whereas I want to pass the display size reported by DDC on to any interested clients. If we decouple the two, everyone is happy. > Xft already uses a separately configurable value (Xft.dpi) that can be used > to adjust the size of text on the screen. > > I suggest a simple calculation for this logical DPI: > > logical_dpi = max (width_in_pixels / (13 2/3), 75); Where do you suggest this be implemented, the client, the font library, or the server ? I really want the server to tell the truth, otherwise apps which care have to decode the server's lie. Equally, most apps wont want to fiddle, so this should probably go in some middleware ? -- Dr. Andrew C.
