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. this is now the output of touchpad-edge-detector Touchpad ETPS/2 Elantech Touchpad on /dev/input/event4 Move one finger around the touchpad to detect the actual edges Kernel says: x [0..2480], y [0..1116] Touchpad sends: x [0..2480], y [0..1116] /^C Touchpad size as listed by the kernel: 88x46mm Calculate resolution as: x axis: 2480/<width in mm> y axis: 1116/<height in mm> Suggested udev rule: # <Laptop model description goes here> evdev:name:ETPS/2 Elantech Touchpad:dmi:bvnAmericanMegatrendsInc.:bvr04PW.ME99.20110908.SKK:bd09/08/2011:svnSAMSUNGELECTRONICSCO.,LTD.:pn305V4A/305V5A:pvr04PW:rvnSAMSUNGELECTRONICSCO.,LTD.:rn305V4A/305V4A:rvr04PW:cvnSAMSUNGELECTRONICSCO.,LTD.:ct9:cvrN/A:* EVDEV_ABS_00=0:2480:<x resolution> EVDEV_ABS_01=0:1116:<y resolution> EVDEV_ABS_35=0:2480:<x resolution> EVDEV_ABS_36=0:1116:<y resolution> And now the touchpad feel more responsive to the two and three finger touches. 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. |
