Two finger scroll stops working suddenly

edit

Hi!

Here I am, happily browsing the web, while suddenly... two finger scrolling stops working on my touchpad! I can't find an easy way to make it come back:

1. Toggling the touchpad settings a few times doesn't work (while i can get edge scrolling to work)

2. Logging out and back in again doesn't work, even switching from Wayland to Xorg and back again.

3. Rebooting solves the problem.

Happened a few times (not often, say a few time every week) at unpredictable intervals. It's no fun having to reboot to fix this :(

Here is info about my system:

• OS: Fedora 26, up to date

• Desktop environment: Gnome

• Display server: Wayland

Relevant output of "sudo libinput list-devices":

Device:           SynPS/2 Synaptics TouchPad
Kernel:           /dev/input/event16

Tap-and-drag:     enabled
Tap drag lock:    disabled
Left-handed:      disabled
Nat.scrolling:    disabled
Middle emulation: disabled
Calibration:      n/a
Scroll methods:   *two-finger edge 
Click methods:    *button-areas clickfinger 
Disable-w-typing: enabled
Accel profiles:   none
Rotation:         n/a

Could anyone help me troubleshoot this issue? This time, I am determined not to reboot before I can actually fix it, and hopefully prevent future occurances, or maybe find a way to reproduce the issue and submit a bug report.

Cheers,

Koen

Edit: It looks like two finger scroll actually stops workings sometime when my laptop wakes up from suspend. It has happened 2-3 times already today. Once, the entire touchpad stopped working, and the only option was to reboot.
