Comment 168 for bug 606238

I have been testing last Dave driver on my Inspiron 17R SE. First, I have change the line added by Dave on alps_model_data to

    { { 0x73, 0x03, 0x50 }, 0x02, ALPS_PROTO_V6, 0xc8, 0xc8, 0 },

because the command mode resp for my touchpad is 0x02 and ALPS_DUALPOINT flag makes no sense as this touchpad has not trackstick.

After loading the module, it seems the touchpad is detected:

psmouse serio1: alps: E6 report: 00 00 64
psmouse serio1: alps: E7 report: 73 03 50
psmouse serio1: alps: alps_enter_command_mode: 73 02 02
psmouse serio1: alps: ver=5, rsp=02
psmouse serio1: alps: E6 report: 00 00 64

psmouse serio1: alps: alps_init: keybit=159FD030
input: PS/2 Mouse as /devices/platform/i8042/serio1/input/input18
psmouse serio1: alps: alps_init: success
input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input19

But it bothers me that both a PS/2 mouse and the AlpsPS/2 touchpad are detected. What is the reason for that? Any ideas?

In any case, the touchpad does not work. However, when I touch the touchpad the events are received by the driver and logged:

psmouse serio1: alps: d: c8 4c 3e 8 24 11 = 588 318 17
psmouse serio1: alps: d: c8 4c 3e 8 24 11 = 588 318 17

x, y and z values make sense according to how I press the touchpad, so the packet format seems similar. However, the mouse pointer doesn't move on the screen, and clicks in the touchpad buttons are not logged.
I guess there is some trouble with the initialization sequence, maybe it is different for my touchpad.

For completeness, I paste here the related X logs, if you have any idea about how to fix this I would be glad to test it. I would like to use the virtual machine stuff to reverse engineering the initialization sequence, but I have no time right now.
