I am sorry. The dmesg-list-of-parameters.txt was wrong again. I seem to
often forget the update command :-(. Here is the correct one, but still
no input from the touchpad, unfortunately.

Hello Po-Hsu,
unfortunately, none of it helped for the touchpad. However my speakers
seem to work now :-) (maybe this was also a system update, I do not
know).
Here is the dmesg-nopnp.txt

Hello nora,
from your dmesg in commment #10:
[0.00] Command line: BOOT_IMAGE=/vmlinuz-5.4.0-58-generic
root=/dev/mapper/vgubuntu-root ro i8042.reset quiet splash vt.handoff=7
it looks like you're still using the "i8042.reset" parameter like in
comment #4, not the "i8042.nopnp". Can you
Hello,
I am sorry, you are right. Here it is.

Title:
No response from TouchPad in 'Acer
In the UEFI there is no "Touchpad" entry. I think it should be in the
"Main" section, right? I tried the other menus as well, but there is
none.
Best regards

Hello,
I used "i8042.nopnp" entry "i8042.nopnp" but it still does not work.
dmesg.txt is attached.
Best regards

Another thing that worth trying is the touchpad setting in your BIOS,
test it with Touchpad set to "Basic" instead of "Advanced" and boot without
that extra parameter.

Hello Maik,
so I guess the touchpad is still not working with this trick?
If not, can you repeat these steps with that "i8042.reset" replaced with
"i8042.nopnp", and check if this works + attach the dmesg.
Thanks!

Hello,
thank you for the quick reply. I followed your instructions and put the
output of
sudo dmesg > ~/dmesg.txt
to the attachment.

Hello,
does it work if you edit your grub file /etc/default/grub with:
sudo nano /etc/default/grub
And add the "i8042.reset" option in the following line, to change it from:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
into something like:
GRUB_CMDLINE_LINUX_DEFAULT="i8042.reset quiet
