[PATCH xf86-video-intel] sna: Avoid clobbering output physical size with
xf86OutputSetEDID()
xf86OutputSetEDID() in the xserver clobbers the physical size, even if we go
from no edid to no edid. This ddx patch is for sure not the best way to fix it,
but works as a test hack at least. So with this xrandr should show the correct
information.
The per screen dpi (as shown by xdpyinfo) is a lost cause. There's just no way
to make that correct when you have multiple displays with different dpi.</pre>
