I've got a new LG gram laptop (LG Electronics 17Z90Q-K.ADC9U1), running Ubuntu 22.04, fully encrypted disk using ZFS. Everything is working except when the computer wakes from suspend, the keyboard no longer works. I've included the output from libinput list-devices. I'm guessing the AT translation may be some kind of buffer translation from a UART device between the keyboard and cpu, but just a guess. My guess is this device is put to sleep, but not woken on power-up. I have to shutdown and power-up every time I store my laptop, so any help is appreciated. I've tried everything I can search online, but to no avail.

Device:           AT Translated Set 2 keyboard
Kernel:           /dev/input/event3
Group:            7
Seat:             seat0, default
Capabilities:     keyboard

Edit: I have since tested the USB ports, and can confirm USB keyboards work on wake. From what I can see in the dmesg, it's an issue with the i8042 IC. I've tried editing all combinations of kernel grub options to no avail.

The question is quite old but since I run into the same issue, this was my fix:

  • edit /etc/default/grub as admin and set the the variable GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"
  • update the grub configuration file with sudo update-grub
  • reboot the system

Hope this help.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.noaux"

worked for me on a VAIO running Ubuntu 23.04.

I figured out the fix. Turns out it was a thermal sensor that was the issue. Run sudo rmmod int3403_thermal to see if it stops the dmesg spam. If it does, insert acpi_mask_gpe=0x6E into /etc/default/grub.
