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 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. 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 devices on Linux still only have experimental support.
