DisplayLink - Dell MKS14b dock with Fedora 24

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.

Fedora 4.9.13-101.fc24.x86_64

Dock: 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. I faced not issues on Fedora 24.

Driver rpm link: 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
