does this touchpad actually report BTN_TOOL_TRIPLETAP when you're clicking with three fingers? Sorry, I posted this reply from launchpad a while ago, but it seems to never have synced. This bug can probably be closed, the problem was in the ubuntu patches, not the upstream code, and it seems to be fixed in the version included in 12.04. I'll include the original comment below. Original Comment: Yes, there is a log of the events from several triple taps here https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/873482/+attachment/2544802/+files/input-events-oneiric.txt if you are curious, however, I do not believe the bug is in the upstream code. Ubuntu has a set of patches on top which tries to count the number of fingers in an event, ignoring in most cases what the kernel sends, but elantech devices do not send enough information for triple taps to register properly with this method. Sorry for the confusion. thanks. closing this bug, please reopen if you notice it again. This has come back, and now seems to be an upstream issue with the recently merged 200_fix_four_tap.patch: "And merged upstream now, so I guess it finally is an upstream bug. http://patchwork.freedesktop.org/patch/9628/ http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/commit/?id=da461b91659d0c64aa6827e065aee2682116a57e (a week after I get the upstream bug closed...)" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/873482 This patch does not work with elantech touchpads, and causes 3 finger tap not to work. This issue seems to be fixed with the patch at http://patchwork.freedesktop.org/patch/9719/ Closing again as per comment #5. Thanks for testing. |
