  • GNOME 3.24.2

  • Lenovo ThinkPad T400

The issue



Two finger scrolling is not working on the touchpad.



I tried enabling two finger scrolling through Settings GUI for Mouse & Touchpad with no result. I also tried setting the value of



org.gnome.desktop.peripherals.touchpad two-finger-scrolling-enabled


to true manually using dconf editor but that didn't work either.



Running libinput list-devices shows that the touchpad on the laptop is SynPS/2 Synaptics TouchPad.



Device: SynPS/2 Synaptics TouchPad
Kernel: /dev/input/event5
Group: 8
Seat: seat0, default
Size: 62x29mm
Capabilities: pointer 
Tap-to-click: disabled
Tap-and-drag: enabled
Tap drag lock: disabled
Left-handed: disabled
Nat.scrolling: disabled
Middle emulation: n/a
Calibration: n/a
Scroll methods: *edge 
Click methods: none
Disable-w-typing: enabled
Accel profiles: none
Rotation: n/a


The line Scroll methods: *edge might be related to the issue. I have set org.gnome.desktop.peripherals.touchpad edge-scrolling-enabled to false and it is indeed disabled.



As a side note, edge scrolling works fine, when enabled.



Any ideas how to make two finger scrolling work?

  • I've the same issue using a Lenovo T440P. 2-finger scrolling worked fine up to the suggested software update I got, so I guess something in the update broke the 2-finger scrolling. Very annoying! Changing the settings didn't help me either.

  • Me again.. After todays update, it works again :). I had to enable the two-finger scrolling again in the settings screen to make it work.
