This same problem affects me.
Ubuntu 22.04
Thinkpad T14s Gen 3
Linux: 6.1.0-1006-oem
When 'Linux S3' is configured in UEFI BIOS as suspend mode, touchpad is
laggy after resume and one of the CPU cores shows high load.
When setting 'Windows and Linux' as suspend mode in the UEFI BIOS (which
Finally I found the fix of this problem (thans archlinux wiki): just reload
"psmouse" module.
Like this:
sudo sh -c 'rmmod psmouse && modprobe psmouse'
Most often touchpad is back to normal after first reload. Sometimes it
does not help and I do 2-3 reloads and it helps.

I am experiencing the exact same symptoms on a Razer Blade 15 (early
2022) model running 5.17.1 from Ubuntu mainline:

The issue only happens after S3 suspend. s2idle does not cause the
problem, but I experience huge battery drain in s2idle (10%/hour).

Can confirm same issue here when set to S3(Linux only). Same problem
also happens in windows - so this is a hardware issue.
I had strange issues when using a non-stock charger as well (lagged but
in a different way).

I have this laptop. Bug happens on S3 suspend, much better on modern
standby (once it took two minutes or so for the touchpad to resume,
every other time it has worked).
Modern suspend does not use much battery. Mine slept for 8:20h last night and
the battery percentage declined from 96% to 94%.
Just to pick up on some of the above comments:
- my understanding is this is a touchpad firmware bug so not much point
reporting it to other distro's as well - it's not a Canonical/Ubuntu
issue either IMO.
- Using S0ix/modern suspend (or 'Windows and Linux') sleep mode setting
in the BIOS is
I am experiencing the same problem. The trackpad seems laggy after
suspend. Also, it seems to commonly get "stuck" in two finger scrolling,
where after lifting one of the two fingers it stays in scrolling mode.
The only way to get it out is to tap on the trackpad randomly to, I
assume, get it to

I can confirm this exact bug. I have the same machine (Thinkpad X1
Carbon 9th gen). However, I am running an up-to-date Fedora 34 system.
For me, changing the sleep mode to what the BIOS calls "Linux and
Windows" (apparently software suspend?) also fixes the problem. I have
not had a chance yet to

Thanks for the testing. The kernel power cycle the ACPI part of the
touchpad, but it doesn't work :(
I guess it's better to stick to s2idle for now.

Tested the kernel provided now and it seems to still act the same.
Attaching GIF with output of the `watch -n0 cat /proc/interrupts`
command.
I also tried switching the sleep mode back to the default (S0ix)
yesterday and this seems to work a lot better with 5.13 kernels than the
5.11 one and

Further investigation reveals that this only occurs when S3 suspend is
enabled in BiOS. The default that is shipped is identified as s2idle in
systemd (just called "Windows 10 and Linux" in BiOS[1]) and is a sort of
software suspend that does not preserve much battery time (which is also
why I
Update: tested new kernels 5.13.7 and 5.14rc4 now and issue still

This is probably a firmware or kernel bug but AFAICT you're not using
any kernel versions supplied by Ubuntu. So we can't support the kernels
you're using here.
