Show me the actual bug. If the copy fails, the new framebuffer contents are just left uninitialised (normal X behaviour) until they get "immediately" redrawn. The subsequent modeset does not depend upon the screen Pixmap fitting into GPU memory, but that it can fit individual CRTC into the GTT. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
