Does anyone have a minimally functional example of how to integrate a panda3d window into a GTK4 window on Wayland? I only found one example from years ago with GTK3 on X11.

#gtk #panda3d #wayland #python

How does one go about measuring the battery drain of a Wayland compositor? Are there any reasonably simple tests to at least roughly check for regressions in this area?

#wayland #linux

Chromium now has initial, experimental support for the xdg-session-management #wayland protocol, which will start shipping in canary channel in the coming days. I've implemented and tested it against Mutter 48, the only compositor supporting it atm - also experimentally - since version 47.

#i3 zůstává mým hlavním prostředím pro každodenní práci, ale musím říct, že GNOME 48 vypadá skvěle.

New in GNOME 48 is the necessary support for keyboard handling by the Orca screen reader in Wayland sessions. As I reported on the Orca mailing list recently, I have updated my system, and this support is so far working as intended. You need Mutter 48 and the latest AT-SPI installed.

Thanks are owed to the software developers responsible for this work.

I’ve been working on a #freebsd from scratch blog post series and was going to skip right over Xorg (preferring #wayland and #sway)…and then I heard about #NSCDE - a reimplementation of #Solaris #CDE look-and-feel via #fvwm

Thanks to work by Christian Moerz, it was a snap. Literally `pkg install Xorg nscde` a change to my .xinitrc and I was up in a pastel bliss again. Run #interlisp on it is a beautiful joy.

I was so impressed AND I got to avoid abandonware security holes and bit rot— so I sent some librepay love. It’s a great project!

For those encountering random video playback application crash heisenbugs on the open source #AMDgpu #Mesa drivers on #Linux (thankfully, with #Wayland this no longer crashes the entire system), with the suspicious "CS has been rejected" error, here is the bug I reported upstream: gitlab.freedesktop.org/mesa/me…

The theory is that the DRM's implementation of AMD's Unified Video Decoder does not properly keep track of #Flatpak process IDs. A patch is underway.

Introducing Casilda - A Wayland compositor widget!

A simple Wayland compositor widget for Gtk 4 which can be used to embed other processes windows in your Gtk 4 application.
It was originally created for Cambalache's workspace using wlroots, a modular library to create Wayland compositors.
Following Wayland tradition, this library is named after my hometown in Santa Fe, Argentina

Now that the storm has passed — I can share an update on screen reader support under Wayland.

As part of STF; GNOME has been working since the end of last year on resolving the matter.

The main issue is that we currently lack a way to “snoop on” or “grab” key events from the compositor.

We now have a draft protocol and implementation in Orca and Mutter thanks to @matt

We are doing our best to get it ready for GNOME 47.

The state of Unix/Linux accessibility is even worse then I feared 🙈 . Fedora has been shipping with a broken screen reader for NINE YEARS?

Orca doesn't work on any distribution that ships with Wayland by default? 😭 (thanks @aral for bringing it my attention)

Do all the distributions and such know that next year they should be accessible?

I can't code and I am not familiar with testing desktop apps, but I would really like to know how I can help to fix this.

(allthough it shows a bigger problem in open source and it's culture)

For eight years Fedora has been shipping GNOME with a broken screen reader!

EIGHT YEARS!

(Wayland has been default on Fedora for eight years – since Fedora 25, released in 2016.)

And a hundred-billion-dollar corporation like IBM ships operating systems today based on it with a broken screen reader.

What is an ableist culture? One in which the people who call this out get ostracised.

Here is my new GNU/Linux distribution guide about Debian KDE 12, the right GNU/Linux distribution for professional digital painting in 2024! Also about three major problems with GNU/Linux distros that will drive away all professional artists, IMO, and how I got kicked out of the Fedora KDE ecosystem with F40, which imposed Plasma6 and Wayland. I hope it helps other artists here!

Is anyone following me a #wayland expert? My Chuwi MiniBook X can only do 50Hz, but users on Windows have managed to crank that up to 60 or even 90. I've tried to use this method to do set a custom resolution/refresh rate on wayland:

davejansen.com/add-custom-reso…

But it didn't work. Any suggestions on how to force wayland to use a refresh rate the display wrongly claims it doesn't support?

Add custom resolution and refresh rate when using Wayland

Monitors and/or adapters don't always return all the supported resolutions and refresh rates to your computer. In those cases you may need to do some finagling to get the right configuration to work.

^{Dave Jansen}

This is kinda a technology preview in order to see if we can ship features like this enabled by default in a lot more apps in the ecosystem.

Thus I'd be very super happy if you'll try it on lots of hardware - be Intel/AMD laptops or ARM64 devices (with V4L2 stateless decoders, such as most #LinuxMobile devices).

Chances that you really hit a zero-copy path are highest with a recent #Wayland compositor - i.e. if you are using #GNOME46, #kde6 or a recent version of #sway, #weston, #cosmic etc.

@nah @fvsch @sonny @matt But here’s the thing: Wayland would never have been made the default if, say, fonts didn’t render correctly. Not having a functional screen reader is as big an issue for people who rely on screen readers. So at some point, someone at Canonical decided that it didn’t matter that people who use screen readers would be excluded. And so they should be ashamed.

#a11y #canonical #wayland #orca #screenReaders #accessibility

So @gnome is removing the x11 session, leaving just the Wayland one.

If this goes out before Orca, the GNOME screen reader, is fixed to work on Wayland, it will mean that people who rely on screen readers will have no way to use one on GNOME. And thus on the major Linux distributions.

So I’m hoping the plan is that this change will not land until GNOME has a working screen reader.

TIL: #Wayland breaks most screen readers, as they are not not intended by design. (they need to interact with other apps)

Wayland is now the default in pretty much all gnome distros.

Orca has workarounds, but they are not merged and not fully working. (And a blind user can't built it without a working screen reader)

I'm not entirely sure if I got this correct, but it seems to me like the #Linux community once again booted the #blind.

I've just pushed the implementation of a GUI for calls in the CLI frontend of #Libervia

That means that you have a full-featured #Qt GUI accessible quickly from your #terminal to make or receive your #XMPP calls. Can also be useful to compensate for clients missing A/V calls.

It works on #X11 and #Wayland and supports desktop sharing.

FOSDEM 2024 - The state of video offloading on the Linux Desktop

^fosdem.org

Update regarding #wayland zero-copy video playback (using hardware planes): with a few small patches it works with #Chromium, both with #vaapi (Intel/AMD) and #v4l2 stateless.

Here a short video using a #rk3399 - the #PINE64 #PinebookPro - playing a 4k 60fps video - only possible with hardware plane offloading. Playback is *almost* smooth already (~50fps), the goal is to catch up with #GStreamer where we get stable 60.

I hope this will all get upstreamed in the coming months.
