From: Guiseppe Bilotta Subject: Revert "Simplify Xft setting fallback" References: boo#1022830 fate#322401 fdo#98909 kde#367499 bmo#1269274 This patch reverts part of commit bdf0820 ("Simplify Xft setting fallback") which forces the DPI to 96 instead of querying the X server for the physical screen dimensions. This is needed for GTK applications to autodetect the DPI of monitors and not depend on manual configuration.
