Sorry, I don't know anything about the firmware software.
So you can NOT expect me to fix the firmware issue.

I have helped answer all the question I can.
I don't know why you blame me like this.

Regards,
Aaron

I believe it should be a firmware issue on trackpoint.

I’ve just checked yesterday and updated the Windows Synaptics drivers to
the newest version, but the reported firmware version (4) stays
unchanged. Did you actually verify your change on firmware version 4 or
only 2 and 3, as the commit message and the comment indicate?

There are several ways to set the speed & sensitivity:
1, udev hwdb/rules;
2, xorg conf;
3, GUI;

It seems users are rarely to use sysfs directly, so the bug is still there.

Sorry. Are you saying “Oops, thanks for the report, I’ll fix it”
or “I’ve just given you three ways to tell libinput my preferred
acceleration, so sysfs is going to stay broken for firmware version
0x04”? I doubt that sysfs is “rarely” used and, mind you, not everyone
is using GNOME and Wayland.
