2015-08-12Drop touch events from the driverPeter Hutterer1-103/+10
This was a bad idea. No-one seems to use this and it gives us little benefits. To even get this feature a number of other features need to be turned off (like two-finger scrolling and tapping). Many of these are enabled by default, if they are disabled a client stack with full touchpad gesture support could in theory support true touchpad gestures. This has never happened. Drop the touch events from the synaptics driver. This allows us to switch the touchpad fully over to look like a relative device, thus also removing the bug that changes the touchpad speed whenever a monitor is added/removed in.

This reverts commit 064445364b4775b25ba49c2250b22b169f291147. The Lenovo *50 series, including the X1 Carbon 3rd always require multiple kernel patches to enable the touchpad buttons. This patch in synaptics only addresses the re-routing of the top buttons. The final iteration of the kernel patches also route the trackpoint buttons through the trackpoint device, rendering this patch unnecessary. These patches are queued for 4.0.

2015-02-18Add a delay between the second button down-up event of double tapsGabriele Mazzotta1-21/+6
Some applications ignore the second tap of double taps because of the lack of a delay between the button down and button up events. Prevent this by replacing the transition from TS_2B to TS_START with a transition from TS_2B to TS_SINGLETAP that emits only a button down event. The button up event will be emitted when transitioning from TS_SINGLETAP to TS_START. In addition, decrease the default value of MaxDoubleTapTime from 180 ms to 100 ms in order to make double taps faster.

2015-01-30Support the new Lenovo X1 Carbon 3rd trackpoint buttonsPeter Hutterer1-0/+42
This device has the trackpoint buttons wired up to the touchpad to send BTN_0, BTN_1 and BTN_2 for left, right, middle. This conflicts with previous touchpads that used those event codes for dedicated scroll buttons. Add an option HasTrackpointButtons that can be set via a xorg.conf.d snippets. This option is not intended as a user-set option, rather we expect distributions to ship some conglomerate of udev/hal rules with xorg.conf snippets that take effect. If the option is set, we look at the three affected buttons at the beginning of HandleState and send button events immediately for them. The HW state is reset to neutral and other processing continues. This saves us from having to synchronize these buttons with software buttons (also present on this device), tapping, etc. Since the buttons are physically different and (mentally) associated with the trackpoint device we also don't need to worry about having finger motion event correctly synced up with the button presses - it's acceptable to send the presses before the motion events.

2014-09-17Limit the movement to 20 mm per eventPeter Hutterer1-0/+33
Touchpads are limited by a fixed sampling rate (usually 80Hz). Some finger changes may happen too fast for this sampling rate, resulting in two distinct event sequences: * finger 1 up and finger 2 down in the same EV_SYN frame. Synaptics sees one finger down before and after and the changed coordinates * finger 1 up and finger 2 down _between_ two EV_SYN frames. Synaptics sees one touchpoint move from f1 position to f2 position. That move causes a large cursor jump. The former could be solved (with difficulty) by adding fake EV_SYN handling after releasing touchpoints but that won't fix the latter case. So as a solution for now limit the finger movement to 20mm per event. Tests on a T440 and an x220 showed that this is just above what a reasonable finger movement would trigger. If a movement is greater than that limit, reset it to 0/0. On devices without resolution, use 0.25 of the touchpad's diagonal instead.

Only parse the SecondarySoftButtonAreas when this option is true, effectively disabling the top buttons when it is false. Likewise, only initialize the SecondarySoftButtonAreas property if we enable support for it. This means that it is now safe to always set a SecondarySoftButtonAreas default in 50-synaptics.conf, and that he section which was intended for use with future pnp-id matching can be dropped, as that is now all handled in the kernel.

2014-04-23Always count tripletap + click as 3 fingerclick on pads with < 3 touchesHans de Goede1-20/+5
When trying to do a 3 fingerclick on a touchpad which only tracks 2 touches, this may register as a 3 or 2 fingerclick depending on the order in which the touchpad detects the fingers. If the 2 outer fingers of the 3 get seen first, then the 2 touches will be too far apart for the heuristic to see them as being close together, and the click gets counted as a 2 finger click. A user will likely never do a 2 finger click with a 3th finger resting somewhere else on the pad, where-as the above misdetection of the clicks is a real issue, so simply always count a click with trippletap set as a 3 finger click on pads which track less then 3 touches. https://bugzilla.redhat.com/show_bug.cgi?id=1086218 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2014-03-18If the touchpad is in TOUCHPAD_OFF mode, allow physical clicksPeter Hutterer1-10/+7
Enabling clicks in off mode also allows for the new Lenovo *40 series to use the top software buttons while the touchpad is disabled. This benefits those that usually disable touchpads altogether but still need the buttons for the trackstick. This changes existing behaviour, but TouchpadOff was always intended to stop erroneous events while typing. Physical button presses are hard to trigger accidentally. On the touchpads that TouchpadOff concept was originally designed for the buttons are nowhere near the keyboard and are physically separated from the touchpad anyway. On Clickpads, triggering a physical click requires more force than accidentally touching the surface. https://bugs.freedesktop.org/show_bug.cgi?id=76156 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com>

This was originally intended as a fixed xorg.conf option only (and still largely is seen as such). Secondary software button are required only on a specific series of touchpads and should be pre-configured by the system and/or the distribution. As such, the property will not be initialized if it is not set in the xorg.conf and will thus not respond to runtime changes. Exposing the property in this way gives clients a chance of detecting if a top software button area is present and thus adjust their behaviour accordingly.

If this happens, it may lead to the following problem scenario: -touch the touchpad in its right click area -let go of the touchpad -rapidly click in the middle area, so that BTN_LEFT gets reported before the new coordinates (such as seen in the trace above, this may require some practicing with evemu-record to reproduce) -the driver registers the click as a right click because it uses the old coordinates from the cumulative coordinates to determine the click location This commit fixes this by: 1) Resetting the cumulative coordinates not only when no button is pressed, but also when there is no finger touching the touchpad, so that when we do get a touch the cumulative coordinates start at the right place 2) Delaying processing the BTN_LEFT down transition if there is no finger touching the touchpad This approach has one downside, if we wrongly identify a touchpad as a clickpad, then the left button won't work unless the user touches the touchpad while clicking the left button. If we want we can fix this by doing something like this: 1) Making update_hw_button_state return a delay; and 2) Tracking that we've delayed BTN_LEFT down transition processing; and 3) When we've delayed BTN_LEFT down transition return a small delay value; and 4) If when we're called again we still don't have a finger down, just treat the click as a BTN_LEFT But this is not worth the trouble IMHO, the proper thing to do in this scenario is to fix the mis-identification of the touchpad as a clickpad.

2014-02-24Add another third state to TouchpadOff for disabling all but button clicksPeter Hutterer1-3/+10
On a new set of laptops like the Lenovo T440 the trackstick does not have physical buttons. Instead, the touchpad's top edge is supposed to acts software button area. To avoid spurious cursor jumps when the trackstick is in use and the finger is resting on the touchpad, add another mode that disables motion events. Enabled by syndaemon with -t click-only, the default stays unchanged. No specific integration with the traditional disable-while-typing is needed. On such touchpads, disabling motion events is sufficient to avoid spurious events and we don't want to stop HW buttons to send events. Note that this only adds the new state to the driver and to syndaemon, there is nothing hooked up otherwise to actually monitor the trackstick. Special note for syndaemon: optional arguments are a GNU extension, so work around it by messing with an optstring starting with ":" which allows us to manually parse the options.

2014-02-20Allow using the entire touchpad for motions started inside the active areaHans de Goede1-5/+6
synaptics offers an option to make parts of the touchpad insensitive. This is ie useful to do palm avoidance rather then palm detection (which may be unreliable) by disabling an area of 15% on the right and left side of the touchpad. Currently a motion which has started inside the active area, stops as soon as it moves outside of the active area. If a motion started inside the active area and thus has already generated some move events, this makes no sense. If the user moves outside of the active area in this case, this is very likely because the user wants to continue the motion. This commit allows such motions to continue normally. I would like to thank Juerd Waalboer for the basic idea, some coding and lots of testing for this fix.

2013-07-19Disable driver scaling for input ABI 19.2Peter Hutterer1-0/+9
For absolute devices in relative mode, i.e. touchpads, the server now takes device resolution into account. Doing so means that the driver mustn't scale, so we deactivate those bits in the driver. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2013-04-26Fix stack smash in clickpad_guess_clickfingers()Peter Hutterer1-6/+9
Apple Magic Trackpad can report 16 slots. In clickpad_guess_clickfingers() the array allocated on the stack contains only 10 slots. As (.num_mt_mask == .num_slots), the function writes out of the bounds of close_point. Use a size 32 bitmask instead and warn if we ever get past 32 touchpoints.

2013-04-05Allow soft button areas to overlap on the edgePeter Hutterer1-8/+8
For percent-based configuration in the form of middle button 33%-66%, right button 66%-0 we'd get an error because of the one device unit overlap. This was neither documented nor useful, because leaving a 1% gap leaves an actual gap between the buttons. Allow for an overlap of one device unit on the edge of the buttons. What's picked in that case depends on the implementation of is_inside_softbutton_area but since one device unit is so small, it doesn't matter. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
