Dell docking station (D3100) not detecting monitors on 20.4.1

  • 772

I installed Ubuntu 20.4 which has connected (via USB 2.0) a Dell Docking Station Model D3100 which has two Dell HP 2311x monitors hooked into it. I have installed DisplayLink with all updates and upgrades implemented onto my system.

I can see via the terminal that DisplayLink via lsusb -d 17e9 but the monitors are not being detected by Ubuntu.

Bus 002 Device 013: ID 17e9:436e DisplayLink 
Bus 002 Device 012: ID 17e9:436e DisplayLink USB3.0 Hub

I genuinely have no idea what's happening.

  1. I had the same issue. Make sure you install the driver. I even had the problem that after one of properly working, it suddenly stopped displaying the screens (on Ubuntu 20.04).

    I installed the latest DisplayLink version from Ubuntu Driver for Downloads Section | Synaptics. I downloaded it, unzipped it and made it executable by right clicking → properties → permissions → checked "Allow executing file as program".

    Disconnect your docking station. Open the terminal (Ctrl+Alt+T), go in the folder that contains the unzipped file, run:

    sudo ./displaylink-driver-5.4.0-55.153.run

    (the last set of numbers are gonna match the latest version, the name of the extracted file).

    Reboot your PC and re-connect your docking station. On regular Ubuntu 20.04 was lagging pretty bad, had to log-in using Ubuntu Wayland.

    Click the 'cog' icon (⚙️) on the login screen, and select the “Ubuntu on Wayland” session. Then login as normal and away you go.
