Did some work on the TTY backend in niri over the past few days. Merged PR for DisplayLink dock support, added "panel orientation" property read, and, based on cosmic-comp code, implemented the necessary logic to avoid screen blanking. Finally, both at niri startup and when switching TTYs, your screen won't flicker, as long as resolution/refresh rate stay the same.

Even when the screen does blank, it'll go faster, as there's now just one modeset instead of two (clear then draw frame).

Took some fighting but I think I've managed to teach the new Alt-Tab to speak to the screen reader

@nikitonsky remember when Discord just appeared? You could just type a name and join a server. That didn't scale much of course, but still, for several months you did not need an account to use a major IM service. Kinda crazy to think about, especially compared to nine circles of hell you have to go through to use some Microsoft applications

What a magnificent narration https://youtu.be/CcceOOPdKZY

Due to some Rust feature unification reasons, some builds of niri will load libwayland-server via dlopen rather than dynamic linking, hiding this dependency from build errors and from autodetection by rpm. This frequently just happens to work since libwayland-server is usually installed from other compositors.

A few lucky users however did hit the runtime panic trying to run niri while missing libwayland-server, making this a rare legitimate case of a "did not install Wayland" problem

if not fren, why fren shaped?

I'm in the skong

today niri turns 2!

With massive thanks to cutenice, we have a new wiki site!!! With good search! :ablobcatbongo:

https://yalter.github.io/niri/

Make sure not to miss the new Since: annotations :blobcat:

The site uses Material for mkdocs, and we retained full compatibility with GitHub Wiki, meaning all existing links keep working.

Also thanks everyone for several suggestions and test wikis in the GitHub discussion!

#niri

Merged the "window positions and sizes in IPC" PR. Please test and report if anything's broken or missing, we have time to fix it until the next release.

https://yalter.github.io/niri/niri_ipc/struct.Window.html#structfield.layout

Here's a quick quickshell test I threw together that draws floating windows as rectangles.

Thanks yrkv for getting the PR mostly complete!

#niri

Yesterday dove into one of the older animation jank bugs in niri: quickly resizing a window back and forth would cause adjacent windows to jump. This problem is hard to trigger unless you're specifically trying to (then it's easy), but it was causing "downstream" problems for more complex actions.

The fix was simple enough, but I imagined enough "interesting" cases around it and decided to write a whole bulk of tests. Check this out, all thanks to our layout and clock code!

niri v25.08 is now released with a logo, xwayland-satellite integration, basic screen reader support, NVIDIA screencast flickering fix, window positions and sizes in IPC, and many other improvements! :ablobcatbongo:

Read the notes here: https://github.com/YaLTeR/niri/releases/tag/v25.08

now i need at least a month off from any release notes preparation 😴

#niri #smithay #wayland #rust

Implemented basic AccessKit integration for niri based on @DataTriny's proof-of-concept. I have little experience with screen readers, and also had several questions, so I would appreciate more eyes and testing on the PR:

#niri #a11y

Rearranged and expanded quite a bit the design principles page on the wiki: https://yalter.github.io/niri/Development%3A-Design-Principles.html

Give it a read if you're curious about my thinking process about various niri behaviors and such

#niri

Fullscreen refactor pt. 1: track pending vs. current fullscreen state for columns, avoid vertical jump when waiting for window to commit a new buffer.

#niri

Screen reader announcement demo bc apparently you can't attach video and image at once

#niri

Fullscreen refactor pt. 2: added un/fullscreen animations. This one involved quite a lot of moving parts actually, so looking for testing.

https://github.com/YaLTeR/niri/pull/2333

#niri

Finally finished making niri screencasts asynchronously wait for rendering completion before handing the buffer over to PipeWire. This fixes screencast flickering problems on NVIDIA setups.

https://github.com/YaLTeR/niri/pull/2175

This is not PW explicit sync; I can now finish that too (OBS and PW released their fixes), but it'll act more as an optimization on top of the current code (since only OBS can use it for now, and not on its Flathub build (PW is too old there)).

#niri

We made it to 10k stars on GitHub!!!! :apartyblobcat: :apartyblobcat: :apartyblobcat:
