Strange trackpad behaviour after wakeup from suspend (not hibernate/shutdown)

[hw-lunemann]

• Sway Version: 1.7 Archlinux

• Debug Log: still working on catching that

• Configuration File:

# Default config for sway
#
# Copy this to ~/.config/sway/config and edit it to your liking.
#
# Read `man 5 sway` for a complete reference.

# Auto start
exec lxqt-policykit-agent
exec keepassxc

### Variables
#
# Logo key. Use Mod1 for Alt.
set $mod Mod4
# Home row direction keys, like vim
set $left h
set $down j
set $up k
set $right l
# Your preferred terminal emulator
set $term foot
# Your preferred application launcher
# Note: pass the final command to swaymsg so that the resulting window can be opened
# on the original workspace that the command was run on.
set $menu dmenu_path | dmenu | xargs swaymsg exec --

default_border normal

### Output configuration
#
# Default wallpaper (more resolutions are available in /usr/share/backgrounds/sway/)
output * bg /usr/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png fill
#
# Example configuration:
#
#   output HDMI-A-1 resolution 1920x1080 position 1920,0
#
# You can get the names of your outputs by running: swaymsg -t get_outputs

### Idle configuration
#
# Example configuration:
#
# exec swayidle -w \
#          timeout 300 'swaylock -f -c 000000' \
#          timeout 600 'swaymsg "output * dpms off"' resume 'swaymsg "output * dpms on"' \
#          before-sleep 'swaylock -f -c 000000'
#
# This will lock your screen after 300 seconds of inactivity, then turn off
# your displays after another 300 seconds, and turn your screens back on when
# resumed. It will also lock your screen before your computer goes to sleep.

### Input configuration
#
# Example configuration:
#
#   input "2:14:SynPS/2_Synaptics_TouchPad" {
#       dwt enabled
#       tap enabled
#       natural_scroll enabled
#       middle_emulation enabled
#   }
#
# You can get the names of your inputs by running: swaymsg -t get_inputs
# Read `man 5 sway-input` for more information about this section.
input type:touchpad {
	dwt disabled
	tap enabled
	natural_scroll enabled

• Description:

  • Close laptop lid / systemctl suspend

  • About twice a week the following happens to me. Upon waking up the trackpad all actions will require one extra finger. Doing anything with a single finder does nothing anymore. Left click turns into a two finger tap, the cursor only moves if dragging with two fingers, right click becomes tapping with three fingers, middle mouse button becomes tapping with 4 fingers. After a few minutes the trackpad goes back to normal.
    This does not happen with any non-wayland wm/de and I haven't tried another wlroots/non-wlroots compositor.
    My Laptop is a Xiaomi Notebook Pro 2018 with

  I'm still trying to catch this happening in a debug log but if there's any more info I can supply in the meantime let me know.

[zsolt-donca]

I have the same issue using a Dell XPS 15. It's rarer for me, and for me the trackpad does not get back to normal. I will post a debug log here the next time I see it.

[hw-lunemann]

It can take a good while before it goes back to normal. Sometimes maybe 10-15 minutes.
When it happens I usually don't bother restarting sway because I don't use the mouse a whole lot.

[xsrvmy]

Something else interesting to check: if you run sudo libinput debug-events before you suspend, you can see upon waking what libinput is receiving. I have had an issue before where sway got disconnected from libinput.

[ackstorm23]

I have this problem too but it happens with my bluetooth mouse as well as trackpad.

I noticed that even if I quit sway, and load it back up, it remains like this. I had to reboot to get this to go away. Has anyone else experienced that or is that unique to me?

I also tested it where I booted, did not start sway/wayland (no display manager), suspended, and came back. I then started sway, and sure enough I have to click twice on everything.

There'a a bug reported in libinput upstream that matches your description: https://gitlab.freedesktop.org/libinput/libinput/-/issues/712

The upstream bug describes the same problem happening in Gnome, so I guess it's unlikely to be a Sway bug?

That bug seems to describe a problem with the touch part of the touch pad, but moving the mouse cursor works perfectly fine in my situation.

Mouse clicks are what are impacted for me. But I'll check it out.

[sespiros]

I also have the same issue and haven't been able to properly debug it yet. A workaround that I use is helps some times:

sudo modprobe -r psmouse
sudo modprobe psmouse

Source

[treibholz]

Same issue here, my workaround is a bit simpler:

• Press CRTL-ALT-F3 (go to console)
• Press ALT-F2 (back to sway)

then my touchpad works again.

[treibholz]

I just had the same behavior with gnome, maybe this is not related to sway at all...

[cedricbu]

Same behavior for me, on Fedora 38 + Sway : after resuming from suspect, touchpad requires 3 fingers for scroll (until I read this issue, I hadn't realized using 3 fingers instead of 2 would work).
I'm dropping an additional piece of info that I haven't seen in the previous comments, maybe it might help someone?

Something that I realized is that the identifier of the touchpad changes when the weird behaviour happens:

When the touchpad requires 3 fingers, it is recognized as a SynPS/2 Synaptics TouchPad:

$ swaymsg -t get_inputs | jq '.[] | select(.type=="touchpad")' 
{
  "identifier": "2:7:SynPS/2_Synaptics_TouchPad",
  "name": "SynPS/2 Synaptics TouchPad",
  "vendor": 2,
  "product": 7,
  "type": "touchpad",
  "scroll_factor": 1.0,
  "libinput": {
    "send_events": "enabled",
    "tap": "disabled",
    "tap_button_map": "lrm",
    "tap_drag": "enabled",
    "tap_drag_lock": "disabled",
    "accel_speed": 0.0,
    "accel_profile": "adaptive",
    "natural_scroll": "disabled",
    "left_handed": "disabled",
    "click_method": "button_areas",
    "middle_emulation": "disabled",
    "scroll_method": "two_finger",
    "dwt": "enabled",
    "dwtp": "enabled"
  }
}

While when it works correctly (e.g.: after reboots, usually), it's being seen as a "Synaptics TM2749-001":

$ jq '.[] | select(.type=="touchpad")' < input-touchpad-working.json 
{
  "identifier": "1739:0:Synaptics_TM2749-001",
  "name": "Synaptics TM2749-001",
  "vendor": 1739,
  "product": 0,
  "type": "touchpad",
  "scroll_factor": 1.0,
  "libinput": {
    "send_events": "enabled",
    "tap": "disabled",
    "tap_button_map": "lrm",
    "tap_drag": "enabled",
    "tap_drag_lock": "disabled",
    "accel_speed": 0.0,
    "accel_profile": "adaptive",
    "natural_scroll": "disabled",
    "left_handed": "disabled",
    "click_method": "button_areas",
    "middle_emulation": "disabled",
    "scroll_method": "two_finger",
    "dwt": "enabled",
    "dwtp": "enabled"
  }
}

This seems to be consistent
