Shaky mouse pointer in linux

Some linux users experiencing there laptop mouse pointer jumping all over the place and shaking without any interaction. This is a known issue in most of debian/ ubuntu based operating system such as ubuntu, kubuntu, linux mint etc.. lets see what we can do to solve this issue.

This issue caused by touch pad drivers. The default touchpad driver in this edition is “libinput” (provided by the xserver-xorg-input-libinput package). If you experience problems with it, you can switch to another driver called “synaptics” 

To know which driver is used by your input devices, run the following command:

sudo grep -i "Using input driver" /var/log/Xorg.0.log

When both drivers are installed, “synaptics” takes priority. To switch to the “synaptics” driver, install it with the command:

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

if this command not working for you, then use this

sudo apt install xserver-xorg-input-synaptics-hwe-18.04 

Then log out and log back in.

To go back to using “libinput”, simply remove the “synaptics” driver:

apt remove xserver-xorg-input-synaptics

Then log out and log back in.
