Decided to try writing a Wayland compositor for fun. Took me a few days to get things going to a video-able state.

also in an act of severe procrastination i decided to try drawing a diagram of the redraw state machine: https://github.com/YaLTeR/niri/wiki/Redraw-Loop

Spent a better part of today, but I've got dmabuf modifier negotiation fully working in my pipewire screencasting code in niri! This happens to finally fix screencasting on NVIDIA GPUs. Still haven't got any GStreamer pipeline working though, maybe needs a pipewire update.

Apparently, my AMD selects a BGRA format modifier that has two planes. Some out of band info I suppose. And on Intel a preferred BGRA modifier has three entire planes!

My Wayland compositor, niri, turns one today! :ablobcatrave:

Here's v0.1.8 with bind key repeat, screenshot UI pointer toggle, gradient color spaces, wlr screencopy v3 and output management, and lots of other improvements: https://github.com/YaLTeR/niri/releases/tag/v0.1.8

omg, my friend drew a birthday nirik :blobcataww:

i recorded a demo video for the focus-follows-mouse section to showcase it lol

Several days and a lot of hair pulling later, I *think* I got resize transactions working?? Maybe? Hopefully?

Resize transactions is when all windows that must resize together, resize together, with no mismatching frames in between. For example, all windows in a column must add up to the full screen height.

This requires correct configure acks on the client (looking at you, Blender) and very careful state update delaying and resize throttling on the compositor side.

narrator: there was still one case where it didn't work due to a bug

okay, surely this time it definitely works for all correctly written clients

Ivan Molodetskikh

Here's one mainly for people who disable animations: window closing now runs in a transaction with the other windows resizing. This means, no background flicker.

There's been another logo discussion in the niri Matrix room with some quite interesting concepts emerging. Here's one by Endg4me_ with edits by bluelinden and myself, and inspiration from a concept by ElKowar.

What do you think?

I'm working on an "event stream" IPC for niri where you get notified about events as they happen. For example, "workspace switched" or "keyboard layout changed".

To give it a good test, I actually started implementing native niri support in Waybar. You can give it a try too: https://github.com/YaLTeR/niri/pull/453#issuecomment-2317110904

I finished the initial event stream IPC implementation for niri. My Waybar fork implements a decent amount of the modules niri/workspaces, niri/window, niri/language. Please give that a try, also anyone who makes IPC scripts or bars please give a try to the event stream IPC itself so we can find any design flaws before merging.

The PR you will need: https://github.com/YaLTeR/niri/pull/453#issuecomment-2321730996

Waybar fork is linked from there.

The other day, Christian Meissl finished updating and publishing the libdisplay-info bindings [1]. This is quite exciting because, unlike edid-rs, it can parse the manufacturer/model/serial from pretty much any monitor.

So, today I spend a few hours integrating the manufacturer/model/serial monitor addressing all throughout niri: config, IPC, niri msg, screencast output selector. You should now be able to write/use "SomeCompany CoolMonitor 1234" everywhere!

Set up CI rustdoc publishing for niri-ipc: https://yalter.github.io/niri/niri_ipc/

This has the entirety of the niri IPC documented, including the new event stream events.

After the Waybar maintainer speedran merging my niri modules and releasing, I would feel bad delaying any longer, so here's niri 0.1.9

Event stream IPC for bars, better window resizing, properly named outputs, on-demand VRR, out-of-the-box fix for NVIDIA flickering, and other improvements!

wtf did I Just Make

Over the past 2 weeks I've been slowly but surely working on the interactive move niri PR [1] by @pajn. It's already got me to fix quite a bit of tech debt in the layout code, which is cool.

The PR is still rough around the edges, but mostly works, and I switched to running the branch on my own systems to give it thorough testing.

(also no, this is not the Floating Layer yet, though it's a good step towards that)

Attaching a video of what it looks like rn

Made interactive move work on touch (and resize too while I was at it), didn't need that many changes actually

#niri

Ivan Molodetskikh

Added a bit of rubberbanding before the window is "dragged out" of the layout. Should help avoid unintended layout changes.

Along with a few more fixes I did, I think interactive move should be good to merge? It's not 100% perfect and jank free, but I'm fairly sure I got all the important things done. Will give it some more testing.
