Two finger scroll stops working suddenly
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:
Toggling the touchpad settings a few times doesn't work (while i can get edge scrolling to work)
Logging out and back in again doesn't work, even switching from Wayland to Xorg and back again.
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
Group: 8
Seat: seat0, default
Size: 100x76mm
Capabilities: pointer
Tap-to-click: disabled
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.
It sounds like it might be a hardware problem. Did you try checking in the logs to see if there are any relevant messages around the time it stopped working?
