Fixing Scroll Speed on Huawei Matebook 14S

• sudo nano /etc/gdm3/custom.conf
• uncomment WaylandEnable=false
• Run xinput and look for which ID your Touchpad is.
  • in my case it's 16 ↳ GXTP7863:00 27C6:01E0 Touchpad id=16 [slave pointer (2)]
• Run xinput --list-props 16 (replace 16 with the ID you found above), look for "Synaptics Scrolling Distance" and not the ID of that
  • in my case it's 359 Synaptics Scrolling Distance (359): -180, -180
• Run xinput --set-prop 16 359 -180, -180 (replace 16 and 359 with the IDs you found above)
  • The smaller the value (e.g. -200) the slower it will be (-100 in the other hand was too quick)

Tip you may also want to disable tap-to-click, in my case I found it too sensitive as my palm would always trigger it.

• Similarly to above, look for the property Synaptics Tap Time and take note of the ID
  • in my case it's 352 Synaptics Tap Time (352): 130
• Run xinput --set-prop 16 352 0

Finally, make it persistent:

• Create a file in your home directory (~/) named .xsessionrc
• Paste all xinput commands you want to be persistent, in my case it's:

xinput --set-prop 16 359 -180, -180
xinput --set-prop 16 352 0
