The ALPS Touchpad has quit working with Ubuntu 20.04 on my Dell laptop.

The ALPS Stick still works, the TouchPad does not.
This seems to have occur with the 5.11 kernel. I updated to 5.13 hoping that the issue had been fixed.
I have read post concerning similar issues with the Synaptics TouchPad.
If I run the commands:
sudo rmmod psmouse
sudo modprobe psmouse proto=imps
The Touchpad works.
I have not had to use a work around for the TouchPad to work until kernel 5.11.
I assume this is a bug or a missed config not built into the kernel.
Does anyone have any additional information or awareness of this issue or if I have overlooked another reason for the cause and effect?
