No, it's correct. The kernel allocates fb0-fb3 for layers and DirectFB additionally gets the 85000000 area for offscreen images etc. > My image is distorted and I am thinking this is why. Which resolution do you use? The kernel might not allocate enough memory. It's also important which device belongs to which layer... -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
