Same here, can't get it to work either.

UPDATE.

I spent a few minutes taking a look at my syslog and found this:

Oct 28 09:35:04 khennig sh[11525]: modprobe: ERROR: could not insert 'evdi': Key was rejected by service
Oct 28 09:35:04 khennig systemd[1]: displaylink-driver.service: Control process exited, code=exited, status=1/FAILURE
Oct 28 09:35:04 khennig systemd[1]: displaylink-driver.service: Failed with result 'exit-code'.
Oct 28 09:35:04 khennig systemd[1]: Failed to start DisplayLink Driver Service.

Did this:

// Not sure if these steps were really necessary

sudo displaylink-installer uninstall

Reboot

// not sure which version of evdi To uninstall... so just uninstalled both I had on the machine
sudo dkms remove evdi/1.11.0 --all -q
sudo dkms remove evdi/1.12.0+dfsg --all -q

sudo apt install --reinstall linux-headers-$(uname -r)

reinstall the displaylink driver and reboot.

Then disabled secureboot and the monitors hooked up to my displaylink hub are working again.

This does not seem to be the same problem the OP had.
Just wanted to let you know that it's possible to get the drivers to work on 22.10.

Hope you find a way to fix your issue.

Kind Regards.

PD: I installed version 5.6.1 of the drivers.
