Update: I got this working today with kernel v5.15. I may have had a few
missing modules missing from my config (I failed to diff old vs new to
specify which ones - I think some I2C related things) but my touchpad is
now recognized and working again!

I am having this issue on my XPS 15 9500 as well, even with the latest
compiled Mainline kernel, v5.14.15 - and there does not seem to be any
hardware issues in Windows.
Palm rejection, gestures, etc do not work at all as it is just reported
as a mouse.

Not sure what status to set this to, since I can't select "Won't Fix."
Maybe "Fix Released" or "Invalid?"

I wanted to hold off until I was sure, but I've confirmed this was a
(second) hardware problem. Dell replaced my laptop's touchpad a second
time yesterday, and after deleting the device in Windows 10 and
refreshing, the OS detected the new touchpad fine. I reinstalled Ubuntu
yesterday and it's
@edholden I'm glad you pinned down the problem! I think you might want
to post this on the askubuntu thread as an answer, and to the kernel
bugzilla as well, and perhaps close the reports on both bugtrackers.

Yes, I've been working on installing Windows, and also speaking with
Dell, whose support techs say a replacement touchpad should have been
the exact same model as the original (except not with a hardware
defect). I wanted to make sure they'd support the laptop, which came
with Windows, as well as
Possible to test Windows? Because I've seen several other XPS 9500
touchpads work just fine.

Thanks. I've attached that; I had previously tried rc6, and it behaved
the same, and that is also the case with rc7.

Ah, I missed that "b"! Unfortunately the 5.10.0 kernel the linux-
oem-20.04b package installs also doesn't fix it (same detection, same
dmesg log lines).

Should be "linux-oem-20.04b" instead of "linux-oem-20.04".

Thanks, Kai-Heng. I've installed linux-oem-20.04 and selected the new
kernel, 5.6.0-1052-oem, on boot. Unfortunately the behavior is
identical. The mouse still appears as "PS/2 Logitech Wheel Mouse" with
all the same information (e.g., event3 in xinput). I checked dmesg and
the four lines you

$ sudo apt install linux-oem-20.04b
