    Phoronix: DisplayLink's USB Display Docks Should Work Nicely On Wayland With GNOME 3.32.1+

    For those with DisplayLink adapters for USB-driven display docks or devices like the ZenScreen, the support for Wayland should be in better standing with GNOME 3.32.1 (or newer) including if using the DisplayLink proprietary drivers...

    ​​​​​​​Why is it so hard to reverse engineer the closed source userspace application for the newer, USB 3-based DisplayLink devices?

      I think no one bother enough. These days you can easily stream DP via USB, so much less people need DisplayLink tech.

        DisplayLink is one of the most stupidest companies on earth, not only are they relying on a niche that is fading away (as you mention their pony trick is becoming mainstream) but they're letting their best developers and hardware engineers go.

        DisplayLink is the archetypical company where management is destroying it from the inside die to over-reliance on MS dependencies.

        Any company who gets in bed with MS ends badly.

          Fully gnome under X11 I can use displaylink. XFCE is broken.

          https://wiki.archlinux.org/index.php..._configuration

          XFCE for displaylink devices have been broken/crashing for years now.

          In fact XFCE displaylink support has been broken longer than Gnome Wayland displaylink support.

          Sorry there are use cases were gnome3 is superior to your xfce solution. Using displaylink devices is one of those areas.

            @Michael: concerning the multi monitor issue, better look for jadahls work on atomic mode setting etc. (https://gitlab.gnome.org/GNOME/mutter/issues/548, https://gitlab.gnome.org/GNOME/mutte...e_requests/525) instead of https://gitlab.gnome.org/GNOME/mutter/merge_requests/73, which most likely won't land. While it basically does work, it's not deemed to be a proper solution by the other devs.

              The latest MALI drivers do not support X11, only wayland... As for gnome3... no thank you. But it is handy as a starting point for "this hardware should work".
              Anyway, displaylink is broken. There are multiple drivers. USB3 variants are unsupported. Only the USB2 variants work. (Before you say anything: try to install those proprietary drivers on an ARM based system, which is in my POS world more common than a PC).

                Doesn't want to defend DIsplayLink, but they actually do have ARM binaries available: https://support.displaylink.com/know...n-raspberry-pi

                  Those are rpi only. The rpi world exists of nothing more than linked to proprietary libraries. Take a look for steamlink for the rpi for instance. You can't really get around the proprietary nature.
                  Not only that, rpi doesn't even have USB3, so it's weird.
                  Anyway, this is the official version of displaylink: https://support.displaylink.com/foru...-linux-support .
                  My experience with closed source (and I mean, I get no source even under NDA), is that they are a big waste of time and money.
                  Already wasted a few thousand dollars to a company that could not keep up with the amount of kernel updates we had. There was no way we could fix things ourselves without source, but an NDA was out of the question.
                  Fortunately that company came out with a usb class version of that device so we just chalked it up to generic R&D loss.
                  The displaylink drivers in the kernel for the USB2 version are the most viable for the amount of kernel changes we have. I don't know what the added benefit is of their proprietary drivers, our cpu's are fast enough.
                  Anyway, it's their loss. We don't do displaylink (based devices) anymore.
