I just got a new mac book pro with a retina display and installed xubuntu. Everything works fine, but the extreme high resolution of the retina display makes text unreadable. So I can change the resolution, but ... well, what do I have the retina display for? Its nice to have such an high resolution.

I can change the size of many things in the options, for example the font size. That works, but many things get out of proportion. And for example in the webbrowser the font is still very small (fixable by Ctrl-+, but I have to redo that for every site I open).

So what is your advice to configure xubuntu for a retina display?
