I set kernel params
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"
My touchpad is recognizing now in xinput as PS/2 Generic Mouse.
xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ A4TECH USB Device id=9 [slave pointer (2)]
⎜ ↳ A4TECH USB Device id=10 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ HP HD Camera: HP HD Camera id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ HP WMI hotkeys id=14 [slave keyboard (3)]
↳ HP Wireless hotkeys id=15 [slave keyboard (3)]
↳ A4TECH USB Device id=16 [slave keyboard (3)]
But it doesn't work properly. Left/right button clicks recognized as cursor
movement, cursor movement set wrong cursor position etc. The same situation on
4.15.0-72-generic
4.15.0-74-generic
