Eric Hi Thanks Peter for the reply, i have wrote a kernel driver, i will check if i can user evdev as an X11 input driver. My question if how can i triger the input driver to roate. which signal / command i have to send to the X11. ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg
