Actual results: new tab doesn't open Expected results: link open in new tab Additional info: Here is the uoutput of : $ udevadm info --query=property --name=/dev/input/event4 DEVLINKS=/dev/input/by-path/platform-i8042-serio-1-event-mouse DEVNAME=/dev/input/event4 DEVPATH=/devices/platform/i8042/serio1/input/input5/event4 ID_INPUT=1 ID_INPUT_HEIGHT_MM=36 ID_INPUT_TOUCHPAD=1 ID_INPUT_WIDTH_MM=80 ID_PATH=platform-i8042-serio-1 ID_PATH_TAG=platform-i8042-serio-1 ID_SERIAL=noserial LIBINPUT_ATTR_RESOLUTION_HINT=31x31 LIBINPUT_DEVICE_GROUP=11/2/e/0:isa0060/serio1 LIBINPUT_MODEL_ELANTECH_TOUCHPAD=1 MAJOR=13 MINOR=68 SUBSYSTEM=input USEC_INITIALIZED=16737840 Also 'ID_INPUT_WIDTH_MM=' and 'ID_INPUT_HEIGHT_MM=' have some correlation with the actual size? because the touchpad is aprox 89 mm width and 45 mm height with rounded corners.

I forgot to mention that my touchpad is an elantech
sounds like bug 1275460, is that correct?
(In reply to Peter Hutterer from comment #4) > sounds like bug 1275460, is that correct? it indeed look similar, but there is a difference in the 'ID_INPUT_WIDTH_MM=' and 'ID_INPUT_HEIGHT_MM=' values (where are this values fetched?), so I guess it can be closed.
also I forgot to mention that I lost the 3 finger tap after removing the 'xorg-x11-drv-synaptics' package from fedora.

If those values are wrong, please run the touchpad-edge-detector tool and attach the output here.

Also I tested the kernel patch from https://bugs.freedesktop.org/show_bug.cgi?id=93583 and can confirm that 3 finger tap to middle click is working with libinput from testing (1.1.5-1.fc23).
sorry, forgot to add this bug number in the update. For reference: https://bodhi.fedoraproject.org/updates/FEDORA-2016-78d0ff2bc4 The size mismatch, ca 10mm in both directions, has some effect on pointer movement and other things. Try this scratch build please: http://koji.fedoraproject.org/koji/taskinfo?taskID=12764067 You should see the touchpad size match the physical measurements now once you installed and rebooted.

Thanks. (As I said before the size is more like 89 x 45 mm)
one mm over or under doesn't matter and it's hard to address anyway - the resolution is an integer number. in your case we have the choice of 27 units/mm -> 91mm width or 28 units/mm -> 88mm width. But one extra mm doesn't matter and is generally lost in the statistical noise. Thanks for testing, I'll get this into systemd upstream.
