Hi, Denis Oliver Kropp, Thanks for your reply!
You just told me that Acceleration was not yet supported by DirectFB's i830 driver. I had find some information about that from directfb-dev mailing list. The website link is http://mail.directfb.org/pipermail/directfb-dev/2007-February/002733.html That guy get the information like below: ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// =======================| DirectFB 1.0.0-rc4 |======================= (c) 2001-2006 United Cultures of Earth - go for outer space!

It's the i830 driver, but it only checks for I830: static int driver_probe( CoreGraphicsDevice *device ) { switch (dfb_gfxcard_get_accelerator( device )) { case FB_ACCEL_I830: /* Intel 830 */ return 1; } return 0; } > 2.
