Running xrandr -current gives a list of available screens: In the above example, provider 1 is the DisplayLink device, and provider 0 is the default display. Provider 1: id: 0xcb cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting Provider 0: id: 0x43 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 2 outputs: 2 associated providers: 1 name:Intel Once the driver is loaded, the DisplayLink monitor is listed as an output provider: Use xrandr or your Desktop Environment's display setup UI to configure your USB monitors running either the udl or displaylink driver. To automatically load udl at boot, create the file udl.conf in /etc/modules-load.d/ with the following contents:įor more information on loading kernel modules, see Kernel modules#Automatic module loading with systemd. Initialized udl 0.0.1 20120220 on minor 1įurthermore, /dev should contain a new fb device, likely /dev/fb1 if you already had a framebuffer for your primary display. Udl 2-1.1:1.0: fb1: udldrmfb frame buffer device Usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Usb 2-1.1: New USB device found, idVendor=17e9, idProduct=03e0 Usb 2-1.1: new high-speed USB device number 7 using ehci-pci Most importantly, the output of dmesg should show something like the following, indicating a new DisplayLink device was found: Although a green screen is the standard indicator of this, other variations have been spotted and are perfectly normal. If your DisplayLink device is connected, it should show some visual indication of this. These instructions assume that you already have an up and running X server and are simply adding a monitor to your existing setup.īefore your system will recognize your DisplayLink device, the udl kernel module must be loaded. If it works then everything below is unnecessary. This is still experimental but supports hotplugging and when works, it is by far the simplest setup. To use the DisplayLink device, connect provider 1 to provider 0:Īnd xrandr will add a DVI output you can use as normal with xrandr. In the above output, we can see that provider 0 is the system's regular graphics provider (Intel), and provider 1 (modesetting) is the DisplayLink provider.
