Title:
Fast Double-tap Treated as Single Click
Status in libinput package in Ubuntu:
Fix Released
Bug description:
https://gitlab.freedesktop.org/libinput/libinput/issues/158
---
Fast double-taps get treated as a single click.
Behavior is present in Ubuntu 18.04 (libinput 1.10.4-1) but not in
17.10 (libinput 1.8.2-1ubuntu2). Still present in 18.10 daily
downloaded 2018.10.08 (libinput 1.12.0-1).
I think this is similar to
https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1762536 with
different hardware.
I'm trying to run Ubuntu 18.04 in a VMware Fusion guest on a Macbook
host. If I double-tap the trackpad fast, it gets treated as a single-
click in Ubuntu. If I double-tap slow (but not too slow) it gets
treated as a double-click. Hitting the narrow window is hard! This
makes it tough to run X in a VM on a Macbook.
I suspect that the host hardware+software delivers a synthesized
double-click to the guest, and that the time between the clicks is
very small.
evemu-record shows two "VirtualPS/2 VMware Virtual Mouse" devices and
a "VMware VMware Virtual USB Mouse". Capture of the first of these is
attached. It looks to me like the second tap comes 8 ms after the
first, and I'm betting that is treated as bounce.
