Hi Carla,

just FYI, I have the same laptop model than you, and can reproduce
your bug report in the same way. I'll work on that to make it working
properly.

Hans, (unfortunately,) this laptop has a ETD0105 touchpad from Elan.
That means that we do not have the X550 touchpad in house, but also
means that we should be able to get in working faster than the X550
one :)

Ok, so 2 things:

1) On the ETD0105 touchpad not working, does the kernel you're using
already have this patch ? :

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/input/mouse/elantech.c?id=271329b3c798b2102120f5df829071c211ef00ed

I tried the RHEL 6.6 kernel (the only I had on a usb disk handy at that time).
The Fedora 21 snapshot (3.17.0) makes it detected properly :)

However, landing 8 fingers on the touchpad makes it completely lost
(waiting few seconds without touching it is enough to get it back
alive).

If not, try that, if it does, it may need some tweaks to that patch,
or something similar.

2) On not having an X550 style touchpad, I got a report from a user
in the bugzilla tracking that, telling us that he is busy reverse
engineering the protocol, and is making good progress, so that one
should hopefully get sorted out soon-ish too :)

I saw that on the bug too. Hopefully, it will work out well.

Cheers,
Benjamin
