[solved] Built-in keyboard freezes randomly

I recently installed Arch Linux on a laptop. A weird keyboard lag appears now and then.

  • For example when changing windows on Gnome 46 (alt + tab) I need to press tab repeatedly to move the selection.

  • When I type (this message for example) I need to wait unpractical amounts of time at random intervals. When it freezes at times Gnomes asks me if I want to kill the application that has become unresponsive.

  • It happens randomly, sometimes I can work for a few hours with no noticeable issue, some other time it’s really unhelpful.

  • It happens with Gedit, Emacs, Firefox, and even the Gnome searchbox. Edit: switching to TTY 3 with ctrl+alt+F3 and editing an Emacs buffer is not impacted by the issue. Reverting back to the GUI of Gnome and editing the same buffer still has the same issue.

  • I have tried on battery and on wire with no difference.

  • I do not use `powertop` or any other power management.

  • I am not able to try with an external keyboard because I don’t have any at the moment.

  • During the freeze time, if the mouse is on the window it disappears, however it can still be seen if moved out of it.

  • The option « Disabling touchpad while typing » doesn’t change the issue if active or not. Disabling the touchpad itself doesn’t change anything either.

$ libinput debug-events --verbose

…
[and then quite correlated with my typing]:
event13 - palm: keyboard timeout
…
event13 - PIXA3854:00 093A:0274 Touchpad: kernel bug: Touch jump detected and discarded.
See https://wayland.freedesktop.org/libinput/doc/1.26.1/touchpad-jumping-cursors.html for details

When I actually place my real palm on the touchpad I can see:

1053: event13 - palm: touch 0 (TOUCH_BEGIN), palm detected (typing)
  ... event13 - button state: touch 0 from BUTTON_STATE_NONE    event BUTTON_EVENT_IN_AREA     to BUTTON_STATE_AREA

 event7   KEYBOARD_KEY            +72.291s      *** (-1) released
1099: event13 - palm: keyboard timeout
1100: event13 - button state: touch 0 from BUTTON_STATE_NONE    event BUTTON_EVENT_IN_AREA     to BUTTON_STATE_AREA   
  ... event13 - gesture state GESTURE_STATE_NONE → GESTURE_EVENT_FINGER_DETECTED → GESTURE_STATE_UNKNOWN
1106: event13 - gesture state GESTURE_STATE_UNKNOWN → GESTURE_EVENT_HOLD_TIMEOUT → GESTURE_STATE_HOLD
-event13  GESTURE_HOLD_BEGIN      +74.461s      1
1111: event13 - gesture state GESTURE_STATE_HOLD → GESTURE_EVENT_HOLD_AND_MOTION → GESTURE_STATE_HOLD_AND_MOTION

It happens even I do absolutely not touch the touchpad in any way. It’s like the keyboard would stop responding, but then all the keys are pressed very quickly. It happens even if I type very very lightly on the keyboard, far from the touchpad.

When looking in evtest’s output, you can see I just hit backspace at timestamp 1722968903.198551 and there is nothing special going on.

I saw nothing obvious when looking at journalctl or dmseg. I am very puzzled hmm

Anyone suffering from this bug? It makes a laptop pretty much unusable.

Re: [solved] Built-in keyboard freezes randomly

What you could try is:

Update your system: sudo pacman -Syu

updating/reinstalling libinput

Log into an X11 session instead of Wayland

Have a great day smile

Re: [solved] Built-in keyboard freezes randomly

Hello, thanks for your help! I do not use X11. The issue was caused by a Gnome misconfiguration. I was able to get rid of it with a mini-reset of Gnome:

$ dconf reset -f /org/gnome/

Re: [solved] Built-in keyboard freezes randomly

@Caocoa how did you determine to do 

dconf reset -f /org/gnome

I'm running into the exact same issue but in Hyprland, and the gnome reset trick isn't working.
