No, we don't need that. The reason why it moves the mouse cursor is that the evdev driver picks it up, and the situation would be exactly the same if xserver-xorg-input-joystick would pick up the device (that's what the driver is used for, a fact that I admit having missed earlier.. ahem). The problem here is that HAL doesn't know that the joystick you plug in is a joystick, instead it thinks it is a mouse (and/or a keyboard). That's why the evdev driver picks it up and all attempts to use /dev/input/js? fails. The correct fix would be to fix hal/kernel to know that it really is a joystick, and blacklist evdev for such devices. Then you should be able to use the joystick just like before input-hotplug. Why wasn't this discovered earlier? The first bug regarding joysticks was filed on Sep 20th (bug 272421 [1]), and it took a while to fix the crasher for good. Input-hotplug had been in use for nearly two months by then, and there simply was not enough time to fix it properly after the crasher was fixed. You have the workaround, which is to disable loading evdev for the joystick locally. That should do for Intrepid. Disabling AutoAddDevices is another way, but then you disable i-h for every input driver and it shouldn't be encouraged on the forums or elsewhere.. t -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
