I have a (bold ?) question.
As previously reported, it works (at least, moves and clicks as
expected, not talking gestures here) in the UEFI BIOS prior to the
loading of any operating system.
Does this mean there is a kind of working driver in code of the UEFI
BIOS ?
Right, it affects all MSFT touchpads.
At the moment there is nothing for MSFT - we will have to be very patient and
hope, that someone can find a driver for it.

As long as no solution is found, here is another solution.

Since it is only a script, this should work in every distribution ;-)

Just repeat again - the fix works where an incorrect driver is detected.
However, no driver is found at all for the LEGION 5 and the touchpad is
therefore not activated.

Thanks Helmut and Ben. These are very precise information and better than any
post elsewhere.
I got no reply from the email contacts provided by Kai-Heng yet...
Anyone with a Lenovo connection ?

Nicolas -- I've seen the R7000 Chinese post
(https://www.cnblogs.com/mikeguan/p/13126497.html), and what it
basically entails is blacklisting hid_multitouch (or disabling it in the
kernel and recompiling), which according to other forums seems to have
an effect on some touchpads, but has no effect
I am a Manjaro developer and we have kernels 4.4 / 4.9 / 4.14 / 4.19 / 5.4 /
5.7 / 5.8
The touchpad doesn't work with one of the kernels.
Screen brightness only works with AMD- or nouveau-Driver, not with the
proprietary driver, like 440.100
The brightness display works, but nothing changes.
.
It's a good question.
In my understanding, the Legion R7000 is the name for China of the
Legion-5 15ARH05. In the Lenovo forum, the Lenovo employee has no access
to the equipment and indicates it's a kernel issue, suggesting it used
to work prior to 5.4 kernel. That looks strange.
I have found the cause so far that the touchpad MSFT0001: 00 04F3: 3140
is recognized, but no suitable driver is found.
With the touchpad ELAN0001: 00 04F3: 3140 it seems to work with a few tricks.
ELAN is also available in the kernel config, but MSFT is not.
I just don't understand why there
Touchpad MSFT0001:00 04F3:3140 is dead on 5.8 rc5 as well.

MSFT Touchpad not working on Lenovo
Hello Didi,
The issue we face could be different : on the Lenovo Legion-5 15ARH05
(which is the object of this bug report) there is no working trick to
boot on Windows then Ubuntu : it just never worked under Linux on the
two BIOS tested (factory I think EUCN16WW and June update EUCN19WW), in
301 - 400 of 418 matches
