Comment 159 for bug 1791427

@thorsten

Thanks.

I loaded the kernel from #94, having set the BIOS to use S3 sleep and having removed that driver from the blacklist. Result: after a fairly long sleep (15 minutes, I think) the touchpad stopped working. I tried a workaround, with no success:

    # echo 1 > /sys/devices/rmi4-00/nosleep
    bash: /sys/devices/rmi4-00/nosleep: Permission denied

But perhaps I need still higher privileges for that command.

Touchpad and trackpad drivers: I have installed everything that `fwupdmgr`, and the Lenovo update utility (via a WindowsToGo install) offered me. What versions of what drivers do we need? (I note also that the WindowsToGo install showed no errors about the trackpad in the log, although admittedly I don't think I tried WindowsToGo when I had s3 enabled in the BIOS.)

Logs: `dmesg | grep pad` and `dmesg | grep point` show nothing relevant. `dmesg | grep sleep` yields this:
