DirectFB only supports one frame buffer device per session. As you are using the multi application core you need to create a secondary session for running the second application. df_andi --dfb:mode=800x600 --dfb:fbdev=/dev/fb0,session=0 & df_andi --dfb:mode=800x600 --dfb:fbdev=/dev/fb1,session=1 --dfb:no-vt,no-cursor In each of these sessions the single frame buffer device is the primary screen. Do you need to run one application controlling both screens? Which hardware is that? It might make sense to write a multi-fb driver like for Davinci or even write a graphics driver from scratch on top of the devmem system. Another nice project could be extending the fbdev system to support multiple fbdevs. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
