ELAN Touchpad is no longer recognized by synaptics after updating to 21.10

After updating my system from 21.04 to 21.10 via do-release-upgrade, synaptics seems to either not load at all, or simply does not recognize my touchpad. I've had problems with my touchpad before, but they're usually remedied easily by uninstalling and reinstalling xserver-xorg-input-synaptics. Now, after updating to 21.10, the touchpad is not recognized (by synaptics) after:

  • Repeatedly uninstalling and reinstalling xserver-xorg-input-synaptics
  • Running modprobe -r psmouse && modprobe psmouse proto=imps
  • Fn + f10 (enable touchpad)
  • Adding i8042.reset i8042.nomux i8042.nopnp i8042.noloop to grub boot options (https://askubuntu.com/a/528429/40894)
  • Forcing insecure boot (sudo mokutil --enable-validation)

However, uninstalling the synaptics driver and rebooting without reinstalling it allowed libinput to take control of it (and it continues to have control even after reinstalling xserver-xorg-input-synaptics. libinput works, however it's clunky and I would like to be able to go back to using synaptics. In addition to this, KDE Plasma's System Settings reports as no touchpad being detected at all.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
