 Sets the reported values for the physical size of the screen. Normally,
 xrandr resets the reported physical size values to keep the DPI constant.
 This overrides that computation.

 New modelines can be added to the server and then associated with outputs.
 This option does the former. The \fImode\fP is specified using the ModeLine
