    Fix for ETPS/2 Elantech Touchpad not working in 12.04

    Hello,

    this is for anyone that has problems with their touchpad not working on Ubuntu 12.04 x32, or that the touchpad appears as a mouse in terminal -> xinput.

    I have an Acer Aspire One 725.

    When I first installed Ubuntu i had problems with the touchpad. No matter what I did it was unresponsive. So I went googling on my other comp to find a fix for this. There is a dirty fix going around that makes the touchpad work temporarily.

    cd /etc/modprobe.d/
    gksudo gedit options.conf


    adding: options psmouse proto=imps to the text file.
    Then running:
    sudo modprobe -r psmouse
    sudo modprobe psmouse


    While this will make the touchpad work, it will no longer be customizable. When you try to find it in terminal -> xinput it will come up as a mouse. Something like PS2 Mouse, or something similar. I wanted to turn of the tap-to-click but couldn't since I couldn't find it neither in system settings or from the command line.

    So what i did was this. First remove the options psmouse proto=imps from modprobe.d

    Then in terminal:
    cd /etc/X11/
    gksu gedit xorg.conf


    And at the end of the text-file add:
    Section "InputClass"
    Identifier "ETPS/2 Elantech Touchpad"
    MatchProduct "ETPS/2 Elantech Touchpad"
    MatchDevicePath "/dev/input/event*"
    Driver "synaptics"
    Option "AreaTopEdge" "50"
    EndSection



    Reboot and Voilá! The touchpad is back and I could remove the annoying tap-to-click which was making my pointer go bananas all over the screen while i was writing.

    Also in xinput it's listed as ETPS/2 Elantech Touchpad.

    Great success!

    So I rebooted my computer now and the touchpad was not working again.

    Apparently the system had made a copy of my xorg.conf with the name xorg.conf~

    I just removed it and things were working again. But why was that created? Some auto-update?

    I'm having a similar problem with ETPS/2 not being recognised.

    Has your solve stuck?

    Best,

    went through the steps outlined above... xinput still does not recognise ETPS/2

    but no replication of xorg.conf

    Hi!

    Everything I did while I was logged in sucked. Couldn't get the touchpad working. I was logged in automatically at first but i had to change that to get the pad working.

    The only solution I have found so far is to:
    1. enable log in.
    2. While you are at the login-screen you can toggle the touchpad ON/OFF by pressing FN+F7.

    By default it's turned off. If you toggle it on and then log in it works like a charm.

    @hasanyonereally

    Xorg.conf~ is a backup file created by gedit when you saved the file. You can disable the creation of backup files if you do not want those any more. They generally end with "~"

    In regards to the problem, I know this is a solved thread, but I would like to post the solution I found for my computer. I have an Acer A0-725, and I struggled with its Elantech touchpad for about a month.

    What I found was that blacklisting the acer-wmi driver was all I had to do. The process is simple:
    Code:
    cd /etc/modprobe.d
    gksudo gedit blacklist.conf
    There is a long list of "blacklist .." items. Add blacklist acer-wmi to the bottom of the list, save, reboot.

    You may have to turn the touchpad on initially. Mine was off by default; but, after turning it on, it has been on at each boot-up.

    Asus EEE 900/Lubuntu 12.04

    I can confirm that blacklisting acer-wmi will restore hardware right click to the eee 900.

    My left click is broken so I can not vouch for its success.

    Huge thanks to empollondefisica--I had searched to no avail until finding this thread.
