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 switched to S3). S3 is suspend to RAM I think.
I have upgraded to a new BiOS release that was made available today (N32ET68W 1.44), and an update to the Embed Controller. This did not help with the issue unfortunately. Seeing as the touchpad works fine with the software suspend, but not the S3 RAM suspend, is there perhaps some module that is not handled correctly when waking up from a more thorough suspend?

No issues whatsoever. But after resuming from even its first suspend after a clean boot, the touchpad feels less responsive, choppy or even laggy. I have tried removing and re-inserting some HID kernel modules, "psmouse", and setting i915.psr_enabled=0 in kernelstubs. Haven't found anything that fixes it yet. The trackpoint works flawlessly all the time, so that is the current backup when I don't have an external mouse connected. My installed OS is Pop!_Os 21.04, but I have tested and confirmed this on a live USB with Ubuntu 21.04 as well. I have also tried upgrading to the latest 5.13.5 and 5.14.0rc2 kernels from the mainline PPA, and tried bumping the libinput10 to 1.18.0 from the impish repos. To recreate: 1. Reboot a X1C9 machine and see that the touchpad works fine 2. Suspend it (to RAM, need to change a BiOS setting so it doesn't do a software suspend) 3. Resume from suspend and see that touchpad acts differently and less responsive than right after a clean boot What is expected: 1. Same responsive touchpad experience after resuming from suspend as right after a clean boot. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu65.1 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: unknown CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: pop:GNOME DistUpgraded: Fresh install DistroCodename: hirsute DistroRelease: Pop!_OS 21.04 DistroVariant: ubuntu GraphicsCard: Intel Corporation TigerLake GT2 [Iris Xe Graphics] [8086:9a49] (rev 01) (prog-if 00 [VGA controller]) Subsystem: Lenovo Iris Xe Graphics [17aa:22d5] MachineType: LENOVO 20XW005PMX Package: libinput10 1.18.0-1 [origin: unknown] PackageArchitecture: amd64 ProcKernelCmdLine: initrd=\EFI\Pop_OS-e5934199-eb91-4da9-9e38-0ad1de1baeb2\initrd.img root=UUID=e5934199-eb91-4da9-9e38-0ad1de1baeb2 ro quiet systemd.show_status=false loglevel=0 splash Tags: hirsute third-party-packages ubuntu Uname: Linux 5.13.5-051305-generic x86_64 UnreportableReason: This does not seem to be an official Pop!_OS package.
