Is there a way to apply (for example the font(size)) changes to
.Xdefaults to all running terminals in a session?
I can apply it to new terminals via loading xrdb -load .Xdefaults, but this doesn't apply to all running terminals.
If it matters I am using urxvt (in daemon mode) as terminal and xmonad as window manager on ubuntu 15.10.
Just for the font sizes I had the idea that one could use the fontsize perl-extension to inject a fontsize change to each open terminal, but I don't know how to do this.
