[Solved]Touchpad issues on my Dell Laptop

Hi there,

Linux noob here, I am having trouble tapping on my touchpad. Clicking on the right and left buttons are working, but I am not able to double tap and open up folders, click on links with a tap, triple touch to get a right click. Basically, the touchpad does not recognize me tapping on it. How can I get these functionalities?

Also, the touchpad is still active while I am typing. How to disable touchpad while typing?

I tried adding these lines to usr/share/X11/ xorg.conf.d/40-libinput.conf

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "on"
        Option "TappingButtonMap" "lmr"
EndSection

It did not change anything.

This is from my autostart

### TOUCHPAD: comment out the next two entries if you don't have one

## Configure touchpad. See 'man synaptics' for more info.
## (Now might be using libinput instead of synaptics.)
synclient VertEdgeScroll=1 HorizEdgeScroll=1 TapButton1=1 2>/dev/null ClickFinger2=3 TapButton2=3

## Disable touchpad while typing
syndaemon -i .5 -K -t -R -d &

### TOUCHPAD END

Any ideas?

Edit 1: Typos

Edit 2:

Output from egrep -i 'synap|alps|etps|elan' /proc/bus/input/devices

N: Name="AlpsPS/2 ALPS GlidePoint"

Edit 3: I learned that I am able to slide two fingers at the same time to left or right and switch between desktops.

Everything that did not change anything needs to be undone.

Then, since synclient seems to recognize your touchpad, I recommend getting the desired functionality with synclient.
Once you have it the way you want you can replace/modify the synclient line in your autostart file.

Good general policy when troubleshooting.

Re: [Solved]Touchpad issues on my Dell Laptop

Time for BunsenLabs to switch from synaptics to xserver-xorg-input-libinput by default?
Anyway, glad you fixed it!
