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 evdev:name:SynPS/2 Synaptics TouchPad:dmi:bvnInsyde:bvrF.53:bd10/24/2012:svnHewlett-Packard:pnHPPaviliong6NotebookPC:pvr0690130000204610000620100:rvnHewlett-Packard:rn3566:rvr21.3A:cvnHewlett-Packard:ct10:cvrChassisVersion:* EVDEV_ABS_00=1208:5767:51 EVDEV_ABS_01=1163:4838:74 EVDEV_ABS_35=1208:5767:51 EVDEV_ABS_36=1163:4838:74 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1825499 Title: Touchpad vertical sensitivity is much higher than horizontal sensitivity [HP Pavilion g6] To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1825499/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
