Comment 117 for bug 1791427

I add that the kernel switch `psmouse.synaptics_intertouch=1`seems to produce spurious middle clicks as desribed on the page https://bugzilla.redhat.com/show_bug.cgi?id=1482640 (even though that page says kernels >= 4.13.6 have fixed the problem).

But I find that my system may not have the latest touchpad firmware - n23gc05w.exe - installed, even though I used WindowsToGo to run Lenovo's auto-update utility. Someone mentioned this firmware update above as a prerequisite for fixing the problem, so I'll install it and report back.
