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...

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 ? - Erwin _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
