trackpad issues

Hi I have a samsung np305e7a. I decided to install Q4OS on it, it installs and runs but the trackpad is slow and jumpy. I tried an alternative Linux distro and it's fine.

From what i can gather there are two drivers LibInput and Synaptics, I don't know how top tell which one is currently in use.

I have Q4OS on my own laptop and i love it.

I'd appreciate any help.

Regards

TheYikes

Re: trackpad issues

If you are using Plasma desktop, open the app launcher (start menu) and look for System Settings. There, search for Input Devices > Touchpad, tweak settings related to cursor acceleration and click the Apply button to see if things go better.
At the same time, you'll see near the top of the GUI which device (Synaptics or something else) is recognized by the system.

If the touchpad is dirty, clean it, and if there are traces of grease, use a fabric slightly dampened with alcohol.

Re: trackpad issues

.. and if you are using Trinity desktop .. Libinput could behave that way on older hardware. We recommend you to switch to Synaptics driver:
$ sudo apt install xserver-xorg-input-synaptics

Disable libinput for touchpad (optional but helps):
$ sudo nano /etc/X11/xorg.conf.d/70-synaptics.conf

Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
EndSection

Save and reboot.

Fine-tune touchpad:
$ sudo apt install xinput
$ synclient FingerLow=30
$ synclient FingerHigh=50
$ synclient VertEdgeScroll=1
$ synclient HorizEdgeScroll=1
$ synclient TapButton1=1
