From e083da9b2a39db20fece61eee2fe67520f05b2e4 Mon Sep 17 00:00:00 2001 From: Mike Hogye Date: Tue, 1 May 2018 11:14:41 -0400 Subject: [PATCH] fix spurious palm detections for Logitech Wireless Touchpad This device frequently reports large pressure values during normal usage. It does not require a tight palm threshold, because it is a desktop device -- not built into a laptop surface -- so we can avoid false positives by setting a very high threshold. https://bugs.freedesktop.org/show_bug.cgi?id=105753 --- udev/90-libinput-model-quirks.hwdb | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/udev/90-libinput-model-quirks.hwdb b/udev/90-libinput-model-quirks.hwdb index 841debe5..13844f5d 100644 --- a/udev/90-libinput-model-quirks.hwdb +++ b/udev/90-libinput-model-quirks.hwdb @@ -278,6 +278,10 @@ libinput:mouse:input:b0003v046DpC408* libinput:mouse:input:b0003v046Dp4024* LIBINPUT_MODEL_LOGITECH_K400=1 +# Logitech Wireless Touchpad +libinput:touchpad:input:b0003v046Dp4011* + LIBINPUT_ATTR_PALM_PRESSURE_THRESHOLD=400 + ########################################## # Microsoft ########################################## -- 2.17.0
