Custom RPM created for Fedora and others

I've tried this out on my setup, but it's not working.

Laptop: Lenovo ThinkPad W520
DisplayLink adapter: Lenovo ThinkPad USB 3.0 Dock
OS: Fedora 22
Kernel: 4.1.3-201.fc22.x86_64

The module is present for my kernel:

Code:

/lib/modules/4.1.5-200.fc22.x86_64/extra/evdi.ko

The kernel identifies the USB device OK:

Code:

kernel: usb 2-1.4.1: Manufacturer: DisplayLink

And the service gets started when I plug in the "dock":

Code:

● displaylink.service - DisplayLink Manager Service
   Loaded: loaded (/etc/systemd/system/displaylink.service; static; vendor preset: disabled)
   Active: active (running) since Thu 2015-08-20 11:00:51 EDT; 14min ago
  Process: 8792 ExecStartPre=/sbin/modprobe evdi (code=exited, status=0/SUCCESS)
 Main PID: 8795 (DisplayLinkMana)
   CGroup: /system.slice/displaylink.service
           └─8795 /usr/lib/displaylink/DisplayLinkManager

Aug 20 11:00:51 w520-pnickerson.portland.desknetinc.com systemd[1]: Starting DisplayLink Manager Service...
Aug 20 11:00:51 w520-pnickerson.portland.desknetinc.com systemd[1]: Started DisplayLink Manager Service.

This is a currently running process:

Code:

/usr/lib/displaylink/DisplayLinkManager

But no additional displays appear in the Fedora settings. And I'm not seeing any log messages about new displays being detected. Any idea where I can look for additional hints as to what's wrong?

dmesg does show some evdi entries, but I think they're normal:

Code:

[  409.913339] evdi: module verification failed: signature and/or required key missing - tainting kernel
[  409.914929] [ ] evdi_init Initialising logging on level 5
