Still testing this one: a window rule to set the xdg-toplevel Tiled state.

By default niri matches it to prefer-no-csd, because the Tiled state currently happens to be the best way to ask always-CSD windows to square their corners.

With this tiled-state window rule you can override it, for example to get title bars (for easy mouse-only gestures) together with square corners (if you're going for a square style with borders, like mine here). You can also e.g. limit it to tiled windows.

#niri

And another thing for today: finally made it so niri waits a bit for the lock screen to paint before locking the session. This fixes the "red flash" issue.

Please test this since it's security sensitive. I already caught one mistake before pushing where killing a lock screen, then spawning a new one, would briefly flash the session contents.

(Note that some lockers fade in from transparency, so you'll still briefly see red, that's just the niri locked session background.)

#niri

Since adding tabbed columns, just about everyone is asking for a way to open a new window directly in the focused tabbed column. This is rather complicated, but yesterday I came up with a 1 line change that should cover some workflows (covers how I use tabs at least).

I have logic that restores the view position when you open and close a window right away. Now I enabled it for consume-left, which means that you can open a new window, consume left (into a tab), and the view will go back.

#niri

Today I implemented a new niri screencasting feature: the dynamic cast target.

It shows up as a special "window" in the portal dialog. Once you select it, you can change what it casts with niri binds! Switch between windows, monitors, and in the future maybe workspaces and other stuff. Works with OBS, browsers, anything else.

I also wrote a wiki page with all our screencasting-related features: https://github.com/YaLTeR/niri/wiki/Screencasting

Thanks @elkowar for coming up with the dynamic cast idea!

#niri

Had to show slides a few times for uni lately, which motivated me to add this next feature.

Windowed fullscreen, also known in other WMs as fake or detached fullscreen, makes the window think that it went fullscreen, while in reality keeping it as a normal window. Useful in combination with apps like Google Slides to hide the browser UI without taking up the whole screen, especially on ultrawide monitors.

Wiki section: https://github.com/YaLTeR/niri/wiki/Screencasting#windowed-fakedetached-fullscreen

#niri

This one seems simple, but actually turned out quite tricky to implement.

I wrote niri code under the assumption that the fullscreen state does not apply immediately: we send a configure to the window, then only at a later point it commits in response. Windowed fullscreen breaks this because in some cases it can apply instantly (going from real to windowed fullscreen needs no state change from the window).

#niri

After trying a few approaches, I ended up doing it "properly" by associating the (entirely compositor-side) windowed fullscreen state to window configures and commits. This lets niri correctly track if a given fullscreen window commit was real fullscreen (so e.g. we need to draw a black backdrop), or if it was windowed fullscreen.

This even works across a chain of toggling windowed fullscreen, then the window slowly acking and committing them, and I have a test to verify that.

#niri

New niri users frequently come from other tiling WMs with static workspace systems. For them, dynamic workspaces is an unusual system, and it can be unclear how to use dynamic workspaces effectively. (Especially until we get an Overview type thing.)

I figured I'd write a wiki page describing niri's workspaces in more detail: https://github.com/YaLTeR/niri/wiki/Workspaces I also included an example of how I personally use workspaces on niri.

Hopefully this makes it easier to understand what's going on!

#niri

slowly going through the piled up PRs (how's your weekend going?), today merged the pick-color IPC from nnyyxxxx. comes with Portal support of course

#niri

A secret niri v25.02 feature! Make your floating windows FLOAT by putting this in your config:

window-rule {
match is-floating=true
baba-is-float true
}

Works in the nix flake too  

#niri #wayland

started working on an Overview for niri. very wip, lots to do, got some basic rendering and dragging working though

#niri

today's progress: wheel scrolling up and down, right click to scroll left and right, click on workspace to focus, some keyboard fixes

this is all mouse-only on the video. only currently using a 3rd-party tool for the hot corner (waycorner), i'll integrate that later

#niri

i have this old ASUS Eee PC collecting dust, decided to try if niri will run on it. well, it actually runs! a few shaders failed compiling (ran into ALU instruction limits), but otherwise seems to work

#niri

today's overview progress: some rendering and input fixes, plus implemented built-in hot corner, and workspace switch on drag-and-drop hold. which means that now you can perform an entire drag-and-drop to a different workspace mouse-only!

#niri

spent many hours today trying to make the combined exit overview + switch workspace animation monotonic. This is hard because zoom and vertical movement are separate axes, and you can e.g. "catch" one of them with a touchpad gesture, while the other must continue animating (so you can't easily convert this into rect interpolation).

Ended up working out a correction formula for the workspace Y positions when both axes have matching animations. Appears to behave so far from my testing

#niri

today I opened a draft PR for the Overview, and request everyone to test it and report issues: https://github.com/YaLTeR/niri/pull/1440

also, today's new overview feature: drag-and-drop into a new workspace between/above/below!

#niri

POV: GoPro mounted on the xwayland-satellite

#niri

Today: added touch support to the Overview. Somehow, the entire thing just worked first try.

#niri

After some more fixes, and a long rebasing session, I merged the Overview! Please give it more testing using your nearest niri-git package.

https://github.com/YaLTeR/niri/wiki/Overview

#niri

The Eee PC rocking the Overview

#niri

Ppl naturally want to put something in the Overview backdrop, like a blurred version of the wallpaper (see how popular Blur My Shell is). Orthogonally, some ppl want the wallpaper to be static, rather than move with workspaces (it can be distracting).

I'm not prepared to dive head-first into image rendering and blur shaders yet, so I made it possible to put a layer surface into the backdrop. This enables both of those cases, likely even more cool things!

https://github.com/YaLTeR/niri/wiki/Overview#backdrop-customization

#niri

Today, screenshot UI updates! Implemented tablet and touchscreen input for area selection (at long last). And, added a small clickable capture button, so screenshots can now be confirmed tablet-, touch-, or mouse-only!

#niri

After long 3 months of work, I'm glad to release niri v25.05 with the Overview, screenshot UI tablet and touch support, dynamic screencast target and windowed fullscreen, IPC pick-window and pick-color, window urgency, and lots of other things!   

Release notes prepared for your reading pleasure as always: https://github.com/YaLTeR/niri/releases/tag/v25.05

#niri #smithay #rust #wayland

Tagged a niri v25.05.1 hotfix, fixing kitty quick access terminal, numlock, and some jank with hidden cursor.

#niri

Alright after some much needed rest, I set out to deal with the thing everyone has to bump into when setting up niri: some way to use Xwayland. I am still very much *not* planning to integrate Xwayland directly, but with this PR (and an accompanying xwayland-satellite PR), niri will create the X11 sockets and autostart xwl-s on demand, all out of the box with zero configuration. So, it'll work just like other compositors, but with xwl-s instead of direct Xwayland.

https://github.com/YaLTeR/niri/pull/1728

#niri

8k stars! 🎉

#niri

In niri v25.05, the screenshot UI learned to respond to some keyboard window movement bindings by moving the screenshot selection. Now it supports several more movement commands, including moving across monitors. It works similarly to a floating window: the selection origin is preserved relatively, and the size is adjusted by the monitor scale difference. Under the right conditions, it'll match a floating window exactly.

Also, holding Space will now let you move the selection origin!

#niri

...and now moving also works with on a touchscreen with a second touch :) Got this idea from how in osu! you can drag with one finger and press with second/third to "click".

#niri

apparently niri is on the GH trending page today: https://github.com/trending Amidst a sea of LLM repos 🙃

Today I implemented most of the ext-workspace protocol [1] in niri. It lets desktop components (i.e. bars) show workspaces and do some basic operations on them.

The two bars with ext-workspace that I know of are sfwbar and xfce4-panel. Unfortunately, I seem to have surfaced several problems in their implementations. I opened issues in sfwbar; would be great if someone took a look from Xfce. Also if there are other clients I missed?

Everyone who dislikes GitHub Wiki: I finally made a write-down of my requirements/wishes for a replacement. Please feel free to chime in with suggestions: https://github.com/YaLTeR/niri/discussions/1830

#niri

Update on ext-workspace:
- sfwbar fixed all outstanding issues!
- the waybar ext-workspace PR also fixed all issues!
- quickshell impl is on the way

#niri

Out of curiosity, I tried running Orca on niri, and apparently it sort-of works for some apps (I expected nothing to work at all; idk anything about screen readers). However, compared to GNOME Shell, there's quite a few missing or broken things. I documented what I found here: https://github.com/YaLTeR/niri/issues/1904

Is there some "Integrating Orca to Wayland desktops" docs? Like, what the compositor needs to do, who handles the hotkeys and how, etc.

(not actively working on this, just curious)

#niri #a11y

Should've done this a while ago, but I finally wrote contributing guidelines for niri:

https://github.com/YaLTeR/niri/blob/main/CONTRIBUTING.md

With many new users, the stream of issues, discussions and pull requests is quite overwhelming. 😅 You can help! And the contributing guidelines outline the various ways how.

I would especially appreciate help reviewing PRs, though I understand it's the more complex task out of these.

Big thanks to people already answering questions and helping others! 

#niri

Today I implemented fetching keyboard layout options from org.freedesktop.locale1, used by things like distro installers to configure the layout:

https://github.com/YaLTeR/niri/pull/2052

I guess this is the closest thing to global cross-desktop keyboard layout configuration, so it should also help environments like LXQt integrating niri.

Also recently merged: niri now sets a logind session locked hint, useful for e.g. idle tools that put the PC to sleep, but only once the lockscreen is fully up.

#niri

Gathering thoughts on reconciling communities between Matrix and Discord: https://github.com/YaLTeR/niri/discussions/2069

This is a problem I expect we'll face reasonably soon, so if you have some ideas please write in the discussion!

#niri

About finished implementing org.fd.a11y.KeyboardMonitor in niri, necessary for correct screen reader function:

https://github.com/YaLTeR/niri/pull/2060

I tested it with Orca more or less, seems to work, but I'm very new to screen reader workings, so it's possible I've missed something.

This makes Orca announce keys everywhere in niri, and makes grabs work (both modifier with double-press passthrough and keystrokes). Making Orca actually say niri dialogs will be a separate effort.

#niri #a11y

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

#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

Quite comprehensive desktop shell for niri released today: https://github.com/bbedward/DankMaterialShell

Based on QuickShell; made by the same people who started the niri Discord server.

Checking it out now, looks very cool! Though not without a few rough edges to iron out of course
