cause here is that the second finger is detected as palm. Having palm detection enabled during two-finger scroll is probably a mistake. can you verify the touchpad size as 80x44mm? if not, please run the touchpad-edge-detector tool and let me know the physical size. I'm wondering if we need size-restrictions for any behaviour changes here (it's not likely you'll get into the edge zone on a large touchpad) This is what the tool says: [nacho@winterfell ~]$ sudo touchpad-edge-detector /dev/input/event6 Touchpad AlpsPS/2 ALPS DualPoint TouchPad on /dev/input/event6 Move one finger around the touchpad to detect the actual edges Kernel says: x [0..2000], y [0..1400] Touchpad sends: x [0..1960], y [113..1436] /^C Touchpad size as listed by the kernel: 80x43mm Calculate resolution as: x axis: 2000/<width in mm> y axis: 1400/<height in mm> Suggested udev rule: # <Laptop model description goes here> evdev:name:AlpsPS/2 ALPS DualPoint TouchPad:dmi:bvnDellInc.:bvrA14:bd08/19/2015:svnDellInc.:pnPrecisionM4700:pvr01:rvnDellInc.:rn082H3V:rvrA00:cvnDellInc.:ct9:cvr:* EVDEV_ABS_00=0:1960:<x resolution> EVDEV_ABS_01=113:1436:<y resolution> EVDEV_ABS_35=0:1960:<x resolution> EVDEV_ABS_36=113:1436:<y resolution> what's the real size? :) It should be something like: 84x47mm I thought this was set more accurate in the kernel... :) save this below as a separate .hwdb file. look at the 60-evdev.hwdb file for instructions on what to do with this then. evdev:name:AlpsPS/2 ALPS DualPoint TouchPad:dmi:*svnDellInc.:pnPrecisionM4700* EVDEV_ABS_00=0:1960:24 EVDEV_ABS_01=113:1436:30 EVDEV_ABS_35=0:1960:24 EVDEV_ABS_36=113:1436:30 once the hwdb applies reboot and see if that changes the resolution to 24/30 in evemu-describe. Note it won't fix the bug but it should bring the real vs kernel-reported ranges in line Seems to have changed: # EVEMU 1.3 # Kernel: 4.5.5-300.fc24.x86_64 # DMI: dmi:bvnDellInc.:bvrA14:bd08/19/2015:svnDellInc.:pnPrecisionM4700:pvr01:rvnDellInc.:rn082H3V:rvrA00:cvnDellInc.:ct9:cvr: # Input device name: "AlpsPS/2 ALPS DualPoint TouchPad" # Input device ID: bus 0x11 vendor 0x02 product 0x08 version 0x310 # Supported events: # Event type 0 (EV_SYN) # Event code 0 (SYN_REPORT) # Event code 1 (SYN_CONFIG) # Event code 2 (SYN_MT_REPORT) # Event code 3 (SYN_DROPPED) # Event code 4 ((null)) # Event code 5 ((null)) # Event code 6 ((null)) # Event code 7 ((null)) # Event code 8 ((null)) # Event code 9 ((null)) # Event code 10 ((null)) # Event code 11 ((null)) # Event code 12 ((null)) # Event code 13 ((null)) # Event code 14 ((null)) # Event type 1 (EV_KEY) # Event code 272 (BTN_LEFT) # Event code 273 (BTN_RIGHT) # Event code 274 (BTN_MIDDLE) # Event code 325 (BTN_TOOL_FINGER) # Event code 330 (BTN_TOUCH) # Event code 333 (BTN_TOOL_DOUBLETAP) # Event code 334 (BTN_TOOL_TRIPLETAP) # Event code 335 (BTN_TOOL_QUADTAP) # Event type 3 (EV_ABS) # Event code 0 (ABS_X) # Value 1191 # Min 0 # Max 1960 # Fuzz 0 # Flat 0 # Resolution 24 # Event code 1 (ABS_Y) # Value 184 # Min 113 # Max 1436 # Fuzz 0 # Flat 0 # Resolution 30 # Event code 24 (ABS_PRESSURE) # Value 0 # Min 0 # Max 127 # Fuzz 0 # Flat 0 # Resolution 0 # Event code 47 (ABS_MT_SLOT) # Value 0 # Min 0 # Max 3 # Fuzz 0 # Flat 0 # Resolution 0 # Event code 53 (ABS_MT_POSITION_X) # Value 0 # Min 0 # Max 1960 # Fuzz 0 # Flat 0 # Resolution 24 # Event code 54 (ABS_MT_POSITION_Y) # Value 0 # Min 113 # Max 1436 # Fuzz 0 # Flat 0 # Resolution 30 # Event code 57 (ABS_MT_TRACKING_ID) # Value 0 # Min 0 # Max 65535 # Fuzz 0 # Flat 0 # Resolution 0 # Properties: # Property type 0 (INPUT_PROP_POINTER) # Property type 3 (INPUT_PROP_SEMI_MT) N: AlpsPS/2 ALPS DualPoint TouchPad I: 0011 0002 0008 0310 P: 09 00 00 00 00 00 00 00 B: 00 0b 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 07 00 00 00 00 00 B: 01 20 e4 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 02 00 00 00 00 00 00 00 00 B: 03 03 00 00 01 00 80 60 02 B: 04 00 00 00 00 00 00 00 00 B: 05 00 00 00 00 00 00 00 00 B: 11 00 00 00 00 00 00 00 00 B: 12 00 00 00 00 00 00 00 00 B: 14 00 00 00 00 00 00 00 00 B: 15 00 00 00 00 00 00 00 00 B: 15 00 00 00 00 00 00 00 00 A: 00 0 1960 0 0 24 A: 01 113 1436 0 0 30 A: 18 0 127 0 0 0 A: 2f 0 3 0 0 0 A: 35 0 1960 0 0 24 A: 36 113 1436 0 0 30 A: 39 0 65535 0 0 0 commit 7860a9ed77b4dea37570e871552566f86df75e11 Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Mon Jun 13 16:41:43 2016 +1000 touchpad: stop palm detection when a second finger is detected *** Bug 96889 has been marked as a duplicate of this bug. *** |
