![]() ![]() 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 graphical interface to configure your USB monitors running either the udl or displaylink driver. Instead of loading udl manually, you can load the module at boot. 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 # dmesg 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. Provider 1: id: 0x13c cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting Provider 0: id: 0x49 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 2 outputs: 8 associated providers: 0 name:Intel $ xrandr -listproviders Providers: number : 2 If not, continue on the the next steps, which will attach the DVI-I inputs to your GPU. After reboot, see if the Displaylink screens are displaying in your display settings. etc/X11//nf Section "OutputClass"Ī reboot may be required for the setting to be effective. For Xorg use the "modesetting" driver with AccelMethod "none" and MatchDriver "evdi".Ĭreate a file with the following content:.For Xorg it allows configuring DisplayLink monitors using xrandr in the same manner as the udl driver for Wayland no configuration is necessary. If you encounter issues, there are some upstream patches applied to evdi-compat-git AUR as an alternative. Install evdi-git AUR ( evdi AUR is currently obsolete) for the in development kernel module.USB 3.0 DL-6xxx, DL-5xxx, DL-41xx, DL-3xxx Devices If you are using an earlier version of that package or have CONFIG_FB_UDL=m set in your kernel config, you need to blacklist the old kernel module, udlfb, which may attempt to load itself first. This should work without any configuration changes on linux 4.14.9-1 and later. It allows configuring DisplayLink monitors using xrandr. The kernel DRM driver for DisplayLink is udl, a rewrite of the original udlfb driver. Installation USB 2.0 DL-1x5, DL-1x0 Devices a DisplayPort monitor, especially when large portions of the screen are being redrawn. The steps on this page describe the generally most successful methods of using external monitors with DisplayLink.Īlso be warned that even over USB 3.0, a DisplayLink monitor may exhibit noticeably more lag than e.g. While some people have had success in using them, it is generally not an easy process and not guaranteed to work. ![]() ![]() DisplayLink is a technology for connecting displays using USB and WiFi.ĭisplayLink devices on Linux still only have experimental support. ![]()
