Recently I took shipment of a Dell Latitude E6430 (supposedly
certified by Canonical). Sadly, out of the box the multitouch-capable
Alps Dualpoint mouse is detected as a generic PS/2 device (bug filed
here[1]). After a bit of poking around I figured out the signature

As noted above using the qemu serio logging doesn't work.
The driver only enables multitouch if it sees the right
name for the device in the DSDT.

After doing some fiddling around myself, I've put together a few tools
and I think I now have the beginnings of an understanding of the report

appear to be 6 bytes long, consistent with earlier versions of the
protocol. The first

Hopefully I'll find some more time in the next few days to figure out
the last few bits (primarily how multitouch events work). I wouldn't be
sad if someone finished the task for me, however.
Success! As it turns out, the process was actually

Ben -
I tried your fix on a Dell Inspiron 15R N5110 (I15R). It did not work.
Things I noticed:
1) Consistent with prior observations, the touchpad E7 signature for it
is: 0x73 0x03 0x50, different than yours on the E6230.
Alright. Good to know.

Dmitry, all,
To clarify my comment. Our protocol utilizes 8 bytes which are needed
in our driver. In order for the Linux system to accept 8 bytes of
data, the Linux psmouse system driver is required to be modified.
Without this modification, the driver

How do I pass the gpio and interrupt stuff to the kernel module.. I

Can you comment if this is also same problem with invalid packets
on E6440/E7440 machines?
Hi Pali,

The invalid packets on the Exx40 machines I believe is caused by some
behavior
