Bug Description

Since upgrade from Ubuntu 17.10 to Ubuntu 18.04 I have issues with tap to click. Approximately 50% of taps does not work as clicks. I do not know if it is general issue or an issue related to my HW (Lenovo L450) but it is very annoying.

Does the problem only occur with the touchpad, and never with a mouse?

If it's occurring with a mouse too, the see these:

Mouse clicks works properly - no missed clicks.

OK. You appear to be using the synaptics touchpad driver (which is expected in Xorg sessions after an upgrade).

I will move this bug to the synaptics driver.

In the meantime you can switch to using libinput by removing synaptics:

  sudo apt remove xserver-xorg-input-synaptics

affects: libinput (Ubuntu) → xserver-xorg-input-synaptics (Ubuntu)

Well, after uninstalling xserver-xorg-input-synaptics it seems to be working fine. At least short testing looks promising. Bud bad is two-finger scrolling stopped working. I can only switch to edge scrolling, which works, but when two-finger scrolling is enabled, it does not work.
