Re: [PATCH app/xrandr] Document that --dpi and --fbmm options set DPI of whole X screen

The "default value 96" is confusing me, perhaps a simple reordering may help: physical size using whatever pixel size will be set (default 96 DPI). It does not have any useful meaning for multi-monitor configuration. > .IP "\-\-newmode \fIname\fP \fImode\fP" > New modelines can be added to the server and then associated with outputs. > This option does the former.
