Title:
After suspend, three fingers needed for two-finger scroll
Status in libinput package in Ubuntu:
Confirmed
Bug description:
I enabled two-finger scroll for my touchpad in Settings. Initially,
it worked fine. However, after closing the laptop lid and suspending
the computer, three fingers are needed to scroll. Two fingers just
moves the pointer, as with one finger. Toggling the setting does not
help, nor does logging out and logging back in. Restarting does fix
it - until the computer suspends again.
This is a ThinkPad T440s running Ubuntu 17.10 after upgrading from
17.04. I'm using Wayland with libinput 1.8.2-1ubuntu2. libinput is
my best guess for where the bug lies, but really I have no idea.
