Ubuntu – Synaptics Touchpad missing in Ubuntu 14.04.2 with Dell 5550

14.04delldriverssynaptics

I have a fresh install of Ubuntu 14.04.2 on a new Dell Latitude E5550.
I seem to have two problems.

One. When I run 'xinput' I get:

justin@sunkite:~$ xinput
⎡ Virtual core pointer             id=2 [master pointer (3)]
⎜   ↳ Virtual core XTEST pointer   id=4 [slave pointer (2)]
⎜   ↳ ImPS/2 Generic Wheel Mouse   id=12 [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)]
    ↳ Power Button                 id=8 [slave keyboard (3)]
    ↳ Sleep Button                 id=9 [slave keyboard (3)]
    ↳ Integrated_Webcam_HD         id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
    ↳ Dell WMI hotkeys             id=13 [slave keyboard (3)]

I expected to see a line with "SynPS/2 Synaptics TouchPad" but got none.

Two. When I try to install xserver-xorg-input-synaptics by:

sudo apt-get install xserver-xorg-input-synaptics

I get:

The following packages have unmet dependencies.
 xserver-xorg-input-synaptics : Depends: xorg-input-abi-20
                                Depends: xserver-xorg-core (>= 2:1.14.99.902)
E: Unable to correct problems, you have held broken packages.

As a result I have no extended mouse settings.

  • I would like to answer my own question as I solved this problem.

    I discovered the Dell support web page Latitude E5550/E5450/E5250 Ubuntu driver package (Ubuntu 14.04)

    I downloaded the zip file.

    After extracting I installed touchpad-alps-trusty-dkms_20140325_all.deb (a double-click brings up the Software application). I had to re-boot before I got the proper mouse settings become available. I am now able to use natural scrolling (as was my original goal).

    Kindly compare the screenshot below to my original question.

    Thank-you Dell for the page.
