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:
