Very pleased to report success on connecting my TP300LA running Fedora 24 to a USB 3.0 DisplayLink dock. This would be a very handy way of connecting monitors. At present I can only use the laptop with a monitor connected to its HDMI port.

Here’s a little teaser before we look at the details:

image-title

OS - Fedora 24 running kernel 4.9.13-101.fc24.x86_64

Dock used: Dell MKS14b

Installed the displaylink-rpm driver following the instructions posted for Fedora 25 by reypm at this post. He experienced some issues while attempting to install the DisplayLink driver on Fedora 25. The instructions for Fedora 25 worked without a glitch on Fedora 24.

DisplayLink driver rpm link: fedora-24-displaylink-rpm-1.3.43-2.x86_64.rpm

Checking the status of displaylink.service after installing the driver

[root@tp300la displaylink-driver-1.2.65]# systemctl status displaylink.service
● displaylink.service - DisplayLink Manager Service
   Loaded: loaded (/usr/lib/systemd/system/displaylink.service; static; vendor preset: disabled)
   Active: inactive (dead)

Connected the USB 3.0 cable from the dock after installing the DisplayLink driver and checking the displaylink.service was active

Plugging in the USB cable from the dock
