I had a similar issue on my HP Omen Laptop with Debian 20. After resume
from long suspend (several hours), my touchpad always generated random
button events even while not touched.

I have exactly the same situation as Mathias wrote in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1788928/comments/22

I didn't have i2c_i801 in my blacklist, but adding
"psmouse.synaptics_intertouch=0" to GRUB_CMDLINE_LINUX in
/etc/default/grub solved the problem.
