Description of problem: Trackpad tap to click disabled since upgrade to Fedora 22. Setting in Gnome Control Centre has no effect. Clicking with trackpad's button works fine.

Hi, Thanks for the bug report. To change the setting from the commandline use "xinput set-prop" not "xinput set-float-prop". Other then that this is a gnome bug, changing component. Regards, Hans
Thanks Hans. Yes, set-prop works and as a workaround, works after reboot by adding the following to /etc/X11/xorg.conf/99-libinput.conf: Section "InputClass" Identifier "enable tapping and edge scrolling" MatchDriver "libinput" Option "ScrollMethod" "edge" Option "Tapping" "on" EndSection I did find a Gnome bug and I'll report my situation there: https://bugzilla.gnome.org/show_bug.cgi?id=747956 Now that tapping works I see that palm detection doesn't! https://bugzilla.redhat.com/show_bug.cgi?id=1209753
