rc49,

You may find that the following option is missing:

Code:

Option "NaturalScrolling" "on"

i read this link,,some posted warning there as following..
BEWARE. After uninstalling xserver-xorg-input-libinput I could not use my mouse and my keyboard anymore, so I could not log in. I had to boot with live cd and chroot to my broken OS, reinstall it to fix this. pretty annoying. https://askubuntu.com/questions/9046...mouse-in-17-04

it may cause more problems!!!confused

rc49,

I specifically referred you to the third answer:

In my case, there was no need to remove any package. The only line which was missing in:

/usr/share/X11/xorg.conf.d/40-libinput.conf was:

Code:

Option "NaturalScrolling" "on"

so the whole section looked as the following:

Code:

Section "InputClass"
          Identifier "libinput pointer catchall"
          MatchIsPointer "on"
          MatchDevicePath "/dev/input/event*"
          Option "NaturalScrolling" "on"
          Driver "libinput"
  EndSection

After restart of X session my mouse worked correctly.

Whether this works in your case, I do not know, but it would seem a good place to start.

Various recent versions of Ubuntu have suffered with exactly the same problem.

gnome-control-center can turn that on and off.

You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again.

You have to open the file as root, with sudo.

First, there is a program called, gnome-control-center. Inside there is a applet for touchpads. Inside the applet are adjustments for the touchpad.

Do this to open the file

Code:

$ sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf
