2016-04-15touchpad: add LIBINPUT_MODEL_WOBBLY_TOUCHPAD for the HP 14-ac157tuPeter Hutterer1-0/+8
If some elantech touchpads require a hysteresis, let's use some more generic tag for those touchpads that require correct handling of pointer wobbles. https://bugs.freedesktop.org/show_bug.cgi?id=94897 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com>

libudev's util_replace_chars() replaces the () with underscores so that match would work too but let's use ? instead to make it look like a regex.

2016-03-11touchpad: add quirk for the T450 and T460 generation hardwarePeter Hutterer1-0/+7
The touchpad's sensors are too far apart (or the firmware interferes), causing in a jerky movement visible especially on slow motion. We get a bunch of normal motion events, then only ABS_MT_PRESSURE updates without x/y updates. After about one mm of movement x/y updates resume, with the first event covering the distance between the last motion event. That event is usually accelerated and thus causes a large jump. Subsequent events are sufficiently fine-grained again. This patch counts the number of non-motion events. Once we hit 10 in a row, we mark the first motion update as non-dirty, effectively discarding the motion and thus stopping the pointer jumps. https://bugs.freedesktop.org/show_bug.cgi?id=94379 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Tested-by: Benjamin Tissoires <benjamin.tissoires@gmail.com>

2016-02-10udev: fix ALPS firmware detectionPeter Hutterer2-4/+4
The firmware version is in id.version, not id.model which is always PSMOUSE_ALPS for ALPS devices. The various fw versions are listed in <kernel>/drivers/input/mouse/alps.h and are all hex numbers. Version 8 is actually 0x800, change the match accordingly. Expected side-effect: earlier versions of ALPS touchpads now lose their (erroneous) size assignment.

2016-02-04touchpad: drop motion hysteresis by defaultPeter Hutterer1-0/+3
Some older touchpad devices jitter a fair bit when a finger is resting on the touchpad. That's why the hysteresis was introduced in the synaptics driver back in 2011. However, the default value of the hysteresis in the synaptics driver ended up being 0, even though the code looks like it's using a fraction of the touchpad diagonal. When the hysteresis code was ported to libinput it was eventually set to 0.5mm. Turns out this is still too high and tiny finger motions are either nonreactive or quite jumpy, making it hard to select small targets. Drop the default hysteresis by reducing its margin to 0, but leave it in place for those devices where we need them (e.g. the cyapa touchpads). https://bugs.freedesktop.org/show_bug.cgi?id=93503 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com>

2015-07-28Ignore test devices for libinput contexts not run from the test suiteJonas Ådahl2-1/+5
Add a LIBINPUT_TEST_DEVICE udev parameter to test devices created by the test suite. When an application tries to add such a device to the path backend or when the udev backend discovers such a device, it will be ignored. Only the context when run via the test suite will actually handle these devices. Doing this will enable a user to run the libinput test suite on a system running libinput without having the test suite devices interfering with the actual system. Note that X.org users running an input device driver that is not the libinput X input driver will still need to manually configure the X server to ignore such devices (see test/50-litest.conf).

The System76 Galago Ultra Pro is a rebranded Clevo W740SU with changed firmware strings. To my knowledge, the Clevo W740SU and all its rebrands possess smooth touchpads. In the original bug report[1], a Galago Ultra Pro was returned to the original DMI strings by flashing another firmware. This resulted in the model identified as MODEL_SYSTEM76_CLEVO. Since the actual manufacturer of the W740SU is Clevo and the CLEVO hwdb entry already properly identifies other W740SU rebrands like the Schenker S413, the model should be renamed to match.

2015-02-18Add udev bits to assign LIBINPUT_DEVICE_GROUPPeter Hutterer4-0/+95
The easiest way to get a device group is by looking at the phys path of the input device (which looks like usb-0000:00:14.0-1/input1) and dropping the /inputX bit. The rest is the same for devices that belong together (except on the Cintiq 22HD Touch). Ideally we could just take ATTRS{phys} but we can't select substrings to drop into ENV so we need to do it ourselves. This patch adds a callout that takes a syspath and prints the mangled path, to be used in LIBINPUT_DEVICE_GROUP. The rule triggers on any device that has a non-zero phys attribute, this groups devices like tablets together but also devices like mice with multiple interfaces.
