Tested on three laptops here, Lenovo T61, X220 and an HP EliteBook (?), all with small touchpads. It's hard to have a hand position where the palm touches the touchpad while using the trackpoint. So we might as well save us the effort of monitoring events and enabling/disabling it on demand.
As a side-effect this fixes 1233844, but that's more a coincidence. https://bugzilla.redhat.com/show_bug.cgi?id=1233844 Signed-off-by: Peter Hutterer <[email protected]> --- src/evdev-mt-touchpad.c | 12 +++++++++--- src/evdev-mt-touchpad.h | 1 + 2 files changed, 10 insertions(+), 3 deletions(-) diff --git a/src/evdev-mt-touchpad.c b/src/evdev-mt-touchpad.c index 538c2d7..5b53862 100644 --- a/src/evdev-mt-touchpad.c +++ b/src/evdev-mt-touchpad.c @@ -520,6 +520,9 @@ tp_palm_detect_trackpoint(struct tp_dispatch *tp, struct tp_touch *t, uint64_t time) { + if (!tp->palm.monitor_trackpoint) + return 0; + if (t->palm.state == PALM_NONE && t->state == TOUCH_BEGIN && tp->palm.trackpoint_active) { @@ -1109,9 +1112,10 @@ tp_interface_device_added(struct evdev_device *device, /* Don't send any pending releases to the new trackpoint */ tp->buttons.active_is_topbutton = false; tp->buttons.trackpoint = added_device; - libinput_device_add_event_listener(&added_device->base, - &tp->palm.trackpoint_listener, - tp_trackpoint_event, tp); + if (tp->palm.monitor_trackpoint) + libinput_device_add_event_listener(&added_device->base, + &tp->palm.trackpoint_listener, + tp_trackpoint_event, tp); } if (added_device->tags & EVDEV_TAG_KEYBOARD && @@ -1455,6 +1459,8 @@ tp_init_palmdetect(struct tp_dispatch *tp, tp->palm.left_edge = device->abs.absinfo_x->minimum + width * 0.05; tp->palm.vert_center = device->abs.absinfo_y->minimum + height/2; + tp->palm.monitor_trackpoint = true; + return 0; } diff --git a/src/evdev-mt-touchpad.h b/src/evdev-mt-touchpad.h index f3c2bf7..2466dab 100644 --- a/src/evdev-mt-touchpad.h +++ b/src/evdev-mt-touchpad.h @@ -283,6 +283,7 @@ struct tp_dispatch { struct libinput_event_listener trackpoint_listener; struct libinput_timer trackpoint_timer; uint64_t trackpoint_last_event_time; + bool monitor_trackpoint; } palm; struct { -- 2.4.3 _______________________________________________ wayland-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/wayland-devel
