In addition to showing the need for unifying DRM driver-side APIs within the Linux kernel, NVIDIA’s Linux graphics driver team at XDC2025 also showcased the shortcomings of screencasting under Wayland.

Doğukan Korkmaztürk of NVIDIA presented on the issues that persist with screencasting under Wayland from both the compositor and client perspectives. From the state of explicit synchronization to performance differences compared to X11, there are some pain points that ultimately still need to be addressed for a better screen casting/capturing experience on Wayland.

      The issues may be totally valid but yeah, Nvidia can be expected to have patches ready.

      Looks similar to the Google ffmpeg situation where Google AI file bug reports, bury the developers, and don’t send any patches at all.

        I watched the thing and guy was crying about DRM and asking for help. Half of those presentations were DRM related as a kernel module. Corporate doing corporate things, like BSOD for linux DRM from Google guy presentation.

    Lazy headline from Phoronix makes it sound like Nvidia is just complaining about Wayland. It’s a technical presentation aimed at Wayland developers to discuss shortcomings that make it difficult to implement screen casting. A talk like this from a hardware vendor who is an active contributor to Wayland, and develops/maintains drivers is very helpful, and the first step to addressing/fixing the issues.

    I hate Nvidia just as much as the next guy, but they’re currently a valuable asset for Wayland and Linux graphics in general. In case you aren’t aware, Nvidia was the main driving force behind getting explicit sync support into Wayland, which is a feature that greatly improves performance for modern graphics APIs.

      In case you’re not aware but it took years of fighting NVidia for them to finally conform to standards and conventions agreed by everyone when NVidia didn’t care to participate.

        Can you give an example? There has been a ton of vague non-specific hate towards them in the Linux community ever since Linus gave them the finger. So for the sake of not being ignorant, I’d like to hear specific examples if you have them.

        Don’t get me wrong, I’m all for hating on Nvidia for many different reasons. I’ve hated them since even before the AI and crypto eras.

          Can you give an example?

          Trying to push three different technologies years after AMD, Intel, Mesa, … agreed on GBM.

            The GBM controversy is the (only) one I know about. Afaik, their drivers support GBM today so it’s kind of outdated.

              Well, of course. I literally said this was a fight over years, so of course in the past. You wanted to one example of why the hate and I gave you one example of why the hate.

    why is it every time one of us turks ends up on the news, it’s because of some dumb bullshit? I miss the days of the Yerli brothers and Far Cry, and Muhammed Suiçmez of necrophagist. Even during the pandemic at least we had Uğur Şahin working on the Pfizer-BioNTech vaccine.
