Changes between Version 20 and Version 21 of DPI

v20	v21
14	14	* DPI support is much improved in version 0.16
15	15	* with X11, there are far too many places where the DPI can be looked up, many places where it can be overriden
16		* for virtualized "hardware DPI" which some applications calculate from the virtual monitor dimensions, you will need a patched [/wiki/Xdummy] driver and [/wiki/FakeXinerama]
	16	* for virtualized "hardware DPI" which some applications calculate from the virtual monitor dimensions, you will need a patched [/wiki/Xdummy] driver and [/wiki/FakeXinerama] - without a patched dummy driver, the hardware DPI (as reported by xdpyinfo) cannot be updated at runtime and must be set in advance, either in the xorg.conf file or on the xvfb command line
17	17	* many applications will not reload the DPI settings, so they must be started ''after'' the client connects to get the correct DPI value
