Google tells me you have a
IEI Integration Corp DELL0817:00 044E:121F Touchpad
and that this is a HID over I2C device, which requires the
following kernel modules:
intel-lpss-pci
i2c-hid
hid-multitouch
and then it will work.
My Stretch system has all three of those (4.9.0-8-amd64),
so try modprobing them all and see what results you get.
Thank you for your response.
"lsmod" reveals all three of these modules are installed.
Just for kicks, I modprobe'd all three (with no visible response), but it made no difference.
