Hi! Me again, asking some nerving questions ;-)
Since the system I'm trying to set up is equipped with a touchscreen, a mousepointer makes no sence, too. I tried to disable it via "xsetroot -cursor path_to_empty_bitmap path_to_mask" but this works only for the X background. Placing the mouse cursor above another application, it is set by this to whatever cursor. Is there a better possibility? Thanks, -Cajus
