Worked on Fujitsu AH552
Steps
Find the device name
xinput list
in my case it is
AlpsPS/2 ALPS GlidePoint
then find the current values for the device
xinput list-props "AlpsPS/2 ALPS GlidePoint" | grep -i finger
In my case it was 12, 15, 0
next we have to change the values as per below
12, 12, 0
for that we can use below command
xinput set-prop "AlpsPS/2 ALPS GlidePoint" "Synaptics Finger" 12, 12, 0
Now the touch pad will be normal and also side scrolling should be working.
Finally we have to save the changes permanently, other wise this will not work after rebooting.
Create a bash file
sudo nano /usr/bin/fujitsu-lifebook-ah552-alps-touc-pad-settings.sh
the first line of the text should be this
#!/bin/sh
and after two line paste the command we previously used for changing the values.
xinput set-prop "AlpsPS/2 ALPS GlidePoint" "Synaptics Finger" 12, 12, 0
save the file using shortcut ctrl+o, then exit ctrl+x
make the file executable
sudo chmod a+x /usr/bin/fujitsu-lifebook-ah552-alps-touc-pad-settings.sh
That's all! Do not forget to reboot the machine!
Disable two finger scrolling on mouse setting to enable side scrolling.
