It also allows resizing the framebuffer all the way up to 32767x34767 (assuming malloc succeeds). I didn't try to test the interaction of that with DGA and opted instead to just get rid of DGA support. Let me know if you think DGA in xf86-video-dummy is actually useful for something and I can try to see if that makes sense.</pre> </blockquote> If I understand what this is supposed to allow us to do... I like it. The patches still apply cleanly, but when I try to use the dummy driver, it crashes in libpixman.
