The reason I am posting this is because I have read countless how do I get urxvt to show a background?
it is this simple:
I just installed this terminal off my repo, then went to work on configuring it. darn if I couldn't get that background image to work. Then finially I read a post something about it has to be compiled with that support within it. So I removed the one from my repo, then I downloaded the source code, ./configure --enable-everything , make, sudo make install.
tried it again - and it worked. Set with urxvt.inheritPixmap: true and it shows through the image as well.
the screenShot - it is in i3 without true composite, because I've read that i3 does not render that very well.
