still some issues with X, sometimes it is even a mouse, depending on config. hmm, why is it INPUT_MT_POINTER and not INPUT_MT_DIRECT? #define INPUT_MT_POINTER 0x0001 /* pointer device, e.g. trackpad */ #define INPUT_MT_DIRECT 0x0002 /* direct device, e.g. touchscreen */ Regards, Andreas _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
