Historically and even right now (e.g.: in OpenBSD) upon starting blank X server one would get black/white "mess". It's easy to see things are working right, because this non-blank, non-empty image means that the X started and it's OK.
On FreeBSD the default 'background' after starting X is black background.
It's very hard to tell if it's a bug and there's a problem with a display, especially on T410 with KMS where things don't work out-of-the-box, and X configuration requires fiddling.
It'd be good if X shipped with some non-blank non-black background.

You can start Xorg with the -retro option if you want to have the X pattern back:
startx -- -retro
Can we make this or other non-black option the default?

I think that Wojciech's suggestion is actually a pretty good idea.
It would troubleshooting easier for newcomers, wouldn't it?
