How to fix Touchpad problems in LMDE

Recently a friend brought me a Acer Aspire Laptop to install LMDE. Just started by the LiveCD I realized that with him touchpad could move the mouse cursor, but could not execute anything by clicking the touchpad.

Between the known issues de LMDE this is one of those that we can find, especially in the variant with Xfce and luckily, they provide us with the solution for it. To activate the «Click on tap» in the touchpad we execute in the console:

sudo gedit /usr/share/X11/xorg.conf.d/50-synaptics.conf

and we replace the content of that file, but this other:

Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" Option "TapButton1" "1" Option "VertEdgeScroll" "1" EndSection

We restart the graphical interface (it should work by exiting the session and re-entering) and the Click on it should work. touchpad.

    It clarifies that it is not necessary to restart the system, only the graphical interface.

      True Mauricio .. It happened to me, thanks for the clarification and a pleasure to have you here 😀

      Editorial: By the way .. How many ways can you suggest me to restart the graphical interface?

    How about elav, your contribution worked halfway for me, it can be said, since when gdm appears it works perfectly, but when I log in and start working, goodbye to the configuration. : S

      In other words, when you access your session, the Touchpad stops working. Is that it? Try making a new user to see what happens.

        Sorry for the delay, the touchpad does not stop working exactly, what stops working is the «click on tap». Sorry if I didn't know how to explain 😛

          Thats weird. It worked perfectly for my friend .. We would have to investigate 😕

    Ok, I solved it, I accessed the mouse properties and in the touchpad tab, activate the option: activate mouse clicks with the touchpad. : S

    Thanks for the contribution… 😉

    I think that can be done without editing the Xorg configuration files. All you have to do is enter the mouse properties and activate the click 😀

    *** Command: disable mouse clicks with touchpad, MATE ***

    Disabling mouse clicks (taps, taps, taps) with the touchpad is easily accomplished graphically. For example, in Linux Mint 17 MATE, just go to the main menu> Control Center> Hardware> Mouse> Touchpad, remove the check mark from "Activate mouse clicks with the touchpad" and close this window. This is useful for those of us who usually use the touchpad but, perhaps by touching it a little hard, we accidentally click, which can cause us to lose time, problem, ... We prefer to use the external buttons (usually "below") to click.

    To achieve the same, the following command can be used (in a console or terminal or from the "Run an application" dialog, which appears when pressing the Alt and F2 keys at the same time):
    gsettings set org.mate.peripherals-touchpad tap-to-click false

    To reactivate the keystrokes:
    gsettings set org.mate.peripherals-touchpad tap-to-click true

    To, in a terminal, see if they are active or deactivated:
    gsettings get org.mate.peripherals-touchpad tap-to-click

    It can be useful to have these commands in a script, eg in one that we can execute after starting the Live USB which, in addition to deactivating the keystrokes of the touchpad, can activate the Spanish keyboard layout, put our favorite Firefox search engines, ...

    In GNOME 2 the equivalent commands are:
    gconftool-2 -s -t bool / desktop / gnome / peripherals / touchpad / tap_to_click false
    gconftool-2 -s -t bool / desktop / gnome / peripherals / touchpad / tap_to_click true
    gconftool-2 -g / desktop / gnome / peripherals / touchpad / tap_to_click

    **** Disable touchpad when typing to avoid problems, MATE ****

    If you have a laptop (laptop, netbook, ...) it may have happened to you more than once that you are typing rather fast and suddenly the cursor goes to another place, words or phrases are deleted, copied or cut (and paste) text anywhere, ... (strange things, strange phenomena, inexplicable a priori ...)

    To solve this problem it can be enough to disable the touchpad (touch panel) while we write (it continues to work perfectly and immediately when we stop writing, without any problem). In MATE (eg with Linux Mint 17, qiana) it is achieved by executing the following command (in a console or terminal or from the "Run an application" dialog, which appears when pressing the Alt and F2 keys at the same time):
    [code] gsettings set org.mate.peripherals-touchpad disable-while-typing true [/ code]
    To return to the previous state:
    [code] gsettings set org.mate.peripherals-touchpad disable-while-typing false [/ code]
    To, in a terminal, see the present state:
    [code] gsettings get org.mate.peripherals-touchpad disable-while-typing [/ code]
    To see the entry graphically, just run ...
    [code] dconf-editor [/ code]
    ... and open the branches of the data tree (schemas -schemas- and entries -keys-) until you reach the corresponding entry: org, mate, desktop, peripherals, touchpad, disable-while-typing. To change it, just click on its value (Value), being true (true) when activating the corresponding box or false (false) when deactivating it.

    In order to run dconf-editor, it must first be installed on the computer. It can be done eg from Synaptic, the Package Manager.

    If in addition to (or instead of) dconf-editor we install dconf-cli we can see the value of the input by executing in a terminal:
    [code] dconf read / org / mate / desktop / peripherals / touchpad / disable-while-typing [/ code]
    We can disable the touchpad when writing by executing:
    [code] dconf write / org / mate / desktop / peripherals / touchpad / disable-while-typing true [/ code]
    And so we re-enable it:
    [code] dconf write / org / mate / desktop / peripherals / touchpad / disable-while-typing false [/ code]
    Note: If we install dconf-tools we get both dconf-editor and dconf-cli.

    Sometimes you have to disable the touchpad. For example when it starts to crash and paste text to us, close tabs or windows, etc. without us wanting or ordering it. If we manage well with the keyboard and its shortcuts or we have a practical and inexpensive USB mouse connected, we can safely disable the touchpad.

    In the MATE desktop environment this is easily achieved with this command:
    gsettings set org.mate.peripherals-touchpad touchpad-enabled false
    To reactivate the touch panel:
    gsettings set org.mate.peripherals-touchpad touchpad-enabled true

    It can also be disabled with:
    sudo modprobe -r psmouse
    To reactivate it:
    sudo modprobe -i psmouse
    sudo modprobe psmouse

    It can also be disabled with:
    1st xinput list
    2nd xinput set-prop x "Device Enabled" 0 (instead of x the touchpad id value)
    To reactivate: xinput set-prop x "Device Enabled" 1
