Hi!

It would seem like a fairly complicated task to me - if the framebuffer driver 
supports it, offering DFB a 'unified framebuffer' spanning the different 
screens, then dfb should have no problem...

In any other case, things get pretty complicated. What 
resolutions/refresh-rates are the different frame buffers running at, and what 
is their logical respective orientation (ie which screen appears left or below 
of which other one)?
Are all the framebuffers operating using the same pixelformat? Do they all 
support the same accellerations?
How to handle surfaces that fall partly onto one framebuffer and partly on 
another? Is that even allowed?

All these seem like fairly thorny issues to me...

Richard

Is there a special reason that multiple framebuffers are not supported ? Or is 
it simply because when the project was started the availability of multi head 
cards was rare ?
