I use the freescale LTIB DirectFB example with touch screen(USE TSLIB DRIVER),without report BTN_TOUCH event ,I can not achieve the button click on the screen ,but it can achieve button click in x-windows(openbox).

Within DirectFB example ,when i touch and move ,the cursor move slowly(it can move ,but some delay),does anyone have experience on the DirectFB and touch screen?(I use Vernoix touch screen with GSL2680)
