The only thing I don't like about the default greeter is that the input box with user list etc. is aligned to the left. I want to have it centered. The only ways to customize unity-greeter I found only changed font, logo and background.
I don't see .ui file and people say that this greeter is 'hardcoded'. So, I've downloaded sources from launchpad, but what I found was only a bunch of vala files, no markup or anything related to positioning/aligning, but adding some classes some to elements. No idea how it all works.
What I want is to customize it to look something like
I just need to center those ui elements. Is it even possible?
