OK then. This sounds like a regression in vanilla Ubuntu between versions 18.10 and 19.04. Next please try installing some older kernel versions from here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D then reboot and as soon as the purple screen appears tap Escape. Then navigate through the menus and choose an older kernel version to boot. We need to find out the last kernel version without the bug, and the first kernel version with the bug. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1825499 Title: Touchpad vertical sensitivity is much higher than horizontal sensitivity [HP Pavilion g6] Status in libinput package in Ubuntu: Incomplete Status in linux package in Ubuntu: Incomplete Bug description: After installing Kubuntu 19.04, I found that vertical sensitivity is much higher than horizontal sensitivity.
