Well, as the title explains that's my problem, I'm using 3.18 kernel, and this are my thoughts:

First of all the touchpad wasn't showing up in xinput while I was expecting something like:

⎜ ↳ PS/2 Synaptics TouchPad id=14 [slave pointer (2)]
⎜ ↳ DLL068B:00 06CB:76E9 UNKNOWN id=12 [slave pointer (2)]

the result was:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SI id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ SI id=10 [slave keyboard (3)] ↳ Integrated_Webcam_FHD id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] ↳ Dell WMI hotkeys id=14 [slave keyboard (3)]

I have a USB-mouse connected to the computer so it must be the SI.

I was amazed because I have read this question asking for changing the behaviour of the touchpad while mine isn't even detected so I went to the dmesg, that shows:

[ 11.969125] hid-rmi 0018:06CB:76E9.0004: Device failed to be properly configured

And the /var/log/Xorg.0.log file shows something like:

[ 26.245] (II) config/udev: Adding input device DLL068B:00 06CB:76E9 (/dev/input/event7)
[ 26.245] (II) No input driver specified, ignoring this device.

So the thing it's it can be a problem with either hid-rmi or a problem with the X configuration (probably the hid-rmi but not for sure) or both which is fun. If anybody have any idea about the problem, it'll be welcomed.

Best regards, me.

I found an solution:

Type in the terminal

echo 'blacklist i2c_hid' >> /etc/modprobe.d/blacklist.conf
depmod -a
update-initramfs -u

and reboot

Hope did work for you!!

Got this working on my Alienware 13 with Ubuntu 15.04 by blacklisting the i2c_hid module.

You have to edit the following file /etc/modprobe.d/blacklist.conf and add this line at the end:

blacklist i2c_hid

Reboot and you should be good to go.
