Using the fbdev ioctls also changed the screen resolution. That's still true for the fbdev primary layer, but other implementations really just implement layer control. The only indication of the screen size so far is the tv standard selection, but the screen API is not finished... -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
