[Bug 1825499] Re: Touchpad vertical sensitivity is much higher than horizontal sensitivity [HP Pavilion g6]

[Gael Lafond]

Thanks #29!
Your fix worked for me as well.

I have an old HP Pavillon g6.

I calculated my touchpad edge like so:

1. Physically measure the touchpad.
    Mine is 90mm x 50mm

2. Find the input device used for the touchpad.
    $ ll /dev/input/by-path/
    platform-i8042-serio-1-event-mouse -> ../event1

3. Run edge detector using the measurement done in step 1, on the device found in step 2
    $ sudo touchpad-edge-detector 90x50 /dev/input/event1
    Run the finger on the touchpad until the number stop changing, then hit CTRL+C

4. Edit the evdev config file
    $ sudo vim /lib/udev/hwdb.d/60-evdev.hwdb

    Comment out the whole "HP Pavillon g6" section
    Added the following lines, bellow the now commented out "HP Pavillon g6" section

Bug description:
  After installing Kubuntu 19.04, I found that vertical sensitivity is much higher than horizontal sensitivity.
  Installing xserver-xorg-input-synaptics improved the situation a bit and enabled KDE touchpad setting that were disabled.

  It's very annoying.
