They can -detect 4 or 5 and this information is valuable. - -In commit 63c4fda (Input: synaptics - allocate 3 slots to keep stability -in image sensors), we allocate 3 slots, but we still continue to report -the 2 available fingers. That means that the client sees 2 used slots while -there is a total of 3 fingers advertised by BTN_TOOL_TRIPLETAP. - -For old kernels this is not a problem because max_slots was 2 and libinput/ -xorg-synaptics knew how to deal with that. Now that max_slot is 3, the -clients ignore BTN_TOOL_TRIPLETAP and count the actual used slots (so 2). -It then gets confused when receiving the BTN_TOOL_TRIPLETAP and DOUBLETAP -information, and goes wild. - -We can pin the 3 slots until we get a total number of fingers below 2. - -Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1212230 - -Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> ---- - drivers/input/mouse/synaptics.c | 8 ++++++++ - 1 file changed, 8 insertions(+) - -diff --git a/drivers/input/mouse/synaptics.c b/drivers/input/mouse/synaptics.c -index 3a32caf06bf1..58102970f94f 100644 ---- a/drivers/input/mouse/synaptics.c -+++ b/drivers/input/mouse/synaptics.c -@@ -940,6 +940,14 @@ static void synaptics_report_mt_data(struct psmouse *psmouse, - input_report_abs(dev, ABS_MT_PRESSURE, hw[i]->z); - } - -+ /* keep (slot count <= num_fingers) by pinning all slots */ -+ if (num_fingers >= 3) { -+ for (i = 0; i < 3; i++) { -+ input_mt_slot(dev, i); -+ input_mt_report_slot_state(dev, MT_TOOL_FINGER, true); -+ } -+ } -+ - input_mt_drop_unused(dev); - - /* Don't use active slot count to generate BTN_TOOL events. */ |
