DirectFB on kernel 3.19+

I'm trying to use DirectFB on my PC with nvidia geforce 8800 gts card, but after starting directfb application everything gets black. I can't use keyboard, but after enabling sysrq, I can get out of this using ALT+SysRq+R and then switch back to X, but not always it works. DirectFB log doesn't say anything about errors, but any dfb app is crashing. Here is my dfb log:

On older kernels directfb works, but is very slow.
I also tried using vesafb instead of nouveau, same result.

Re: DirectFB on kernel 3.19+

Dfbterm works, but after typing exit it crashes and I get black screen, again.
