record such a tap with evemu-record please and attach the output here
Created attachment 1086704 [details] evemu-record Here is the record fro, evemu.
Please don't cut the recording, I need the top part of the recording too (with the device description). Without that, I cannot emulate the device here. What laptop is this btw, does the device have physical buttons?
Created attachment 1088438 [details] Complete evemu record Oh sorry about the previous file. I was using the options for evemu record to send the data to a file, however it seems it does so without copying the header into that same file. This new file should contain everything that is needed. By the way, my laptop is a samsung np530u03b, it is a 2012 model (well i bought it then, might be a bit older though). And yes, it has physical button for left and right click. I didn't think about testing it until now but i confirm that clicking both physical buttons at the same time generates a middle click.

(In reply to fabien.chaillou from comment #4) > Oh sorry about the previous file. > I was using the options for evemu record to send the data to a file, however > it seems it does so without copying the header into that same file. oops, that is a bug in evemu then. I'll get that fixed, thanks. as for the 3-finger tapping (note: 3-finger click has a different meaning, see http://wayland.freedesktop.org/libinput/doc/latest/clickpad_softbuttons.html#clickfinger), that seems to be a kernel bug: the second touch point has a position of 0/0 and gets detected (and ignored) as a palm touch. So unless you really had your finger in the top-left corner, that would be bug in the kernel. Benjamin?
Yep, looks like there is a problem in the kernel. Can you attach a dmesg so that we know which version of the Elan touchpad you are using?
Created attachment 1088790 [details] Output of dmesg Here is the ouput of dmesg. I can't however tell me which version of the touchpad i have, sorry ! Hopes it helps.
I updated to fedora 23 and it still happens. Can i be of any help on anything ?
Just a FYI, I have been tracking recently the exact same problem upstream (fdo bug #93583). I don't think I will be able to add a second slot, but the touchpad should report itself as semi_mt. Then, I think we should ignore palm detection for semi-mt devices in libinput.
This should've been fixed with the libinput 1.2 release (see fdo bg in comment 9). If it's still broken please re-open.
Hello Peter, I confirm this is fixed for me. Thanks ! Fabien
