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]: 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
