Hi !!

My enviroment is ...
Ubuntu 18.04 LTS
XPS13 9380 (Dell Laptop)

I maximized the touch pad speed setting, but I want to make it faster.I use 'Settings', 'Tweaks' and 'dconf Editor' as setting application. I felt it late even though it was maximized with "Mouse & Touchpad" in "Settings", so I decided to change the setting with "org.gnome.desktop.peripherals.touchpad.speed" in "dconf Editor", but changing the value only between -1 and 1 could not. Of course I set it to 1, but the speed does not change.
Because the display is 4K, I think that it will be affected, but is there any way?
