*** This bug has been marked as a duplicate of bug 105974 *** This might not be a duplicate, and was specifically opened because the fix for bug 105974 doesn't work for this user. See comment 12 in https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1762536 are you shipping 6dcdfdd513fd8158bc7bacbad8c5c8ba987565a0 in the ubuntu package? looking at this record... https://bugs.freedesktop.org/show_bug.cgi?id=106534 it would seem that it only resolved in part 'cos of the three listed devices the k400+ was not affected by whatever was done to libinput-model-quirks.hwdb as I said elsewhere, it appears that the specific tag LIBINPUT_MODEL_LOGITECH_K400+ was not been added to that hwdb what's the product ID of the K400+? 0x404D? If so, it's in the list of devices added in 6dcdfd. https://wayland.freedesktop.org/libinput/doc/latest/udev_config.html#hwdb has instructions for checking whether LIBINPUT_MODEL_BOUNCING_KEYS is set on your device. If not, then either you have different product ID (check evemu-record's first lines) or there's a typo somewhere in the hwdb. > LIBINPUT_MODEL_LOGITECH_K400+ That tag never existed, at least not upstream and unfortunately bug 106534 is full of noise. From my attachment: Device Product ID (264): 1133, 16461 Otherwise, how do I get that detail for you? And I see this--in my attachment--as well: idProduct 0xc52b Unifying Receiver ID 046d:c52b Logitech, Inc. Unifying Receiver Your udev link re determining bouncing keys, unfortunately doesn't make sense to me (*above my pay grade*). I tried some of that syntax there. All I could get was an event node name for the K400+ but I couldn't see any reference to "bouncing" on that page to take that discovery any further... PS. In all previous Ubuntu releases, this keyboard never had problem with whatever distro flavor; something changed with 18.04. Is it gonna be easier just to buy another keyboard? Sorry for these replies in drips and drabs I since discovered this: [ 4.889018] logitech-djreceiver 0003:046D:C52B.0003: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-4/input2 [ 5.017526] input: Logitech K400 Plus as /devices/pci0000:00/0000:00:14.0/usb2/2-4/2-4:1.2/0003:046D:C52B.0003/0003:046D:404D.0004/input/input3 [ 5.017694] logitech-hidpp-device 0003:046D:404D.0004: input,hidraw1: USB HID v1.11 Keyboard [Logitech K400 Plus] on usb-0000:00:14.0-4:1 > how do I get that detail for you? From comment 5: > (check evemu-record's first lines) anyway, 16461 in hex is 0x404d, so it was part of the commit listed above. The udevadm info output should list LIBINPUT_MODEL_BOUNCING_KEYS if everything is set up correctly. But we don't seem to be getting anywhere. As said twice above, the 6dcdfd commit is part of git master but not yet in 1.10.x. https://launchpad.net/ubuntu/+source/libinput/1.10.7-1 suggests that ubuntu doesn't ship any extra patches on top of 1.10.7. Which means *this patch is not in Ubuntu*. So it won't yet be fixed on your distribution. I'm closing this bug again because unless someone verifies that it's broken on *git master* this is still considered fixed. Note that this is the upstream bug reporting tool, not Ubuntu's bug reporting tool. And unless Ubuntu starts shipping git master, there will be bugs that are fixed here but still broken in Ubuntu. https://wayland.freedesktop.org/libinput/doc/latest/reporting_bugs.html#fixed_bugs Thank you very much! Re Comment 9 and a FYI: Noted that with Fedora 28 (kernel version 4.16.3-301.fc28.x86_64) this K400+ does kinda the same thing I say kinda because (a) while the double-tap behaves the same in both distros (b) selecting text does work with Fedora but not in Ubuntu 18.n Seems it may require more than merely Ubuntu intervention... Please update to libinput 1.11 in f28 updates-testing, any version before that won't have the required patches. If it's broken with that version, then we should probably start a new bug because it's likely the issue is elsewhere. Thank you for the kind comment regarding bug 106534.
