Well, what other options do you have if your device has only one button and nothing else (i.e. it's a mouse, not a touchpad)? Anyway, I hope in 5 years distros will switch to pure evdev-based interfaces and won't use mousedev at all. > Nevertheless, I can see the point in moving > away from user-land decisions in the kernel.

Mousedev purpose is to provide good enough emulation in absence of a native driver and that's it. Also, the default value would not work well on high-resiolution devices (like Synaptics) and would require user fiddling with kernel parameters - not worth it in my opinion. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
