Fluid tile - Automatic tiling for your apps

submitted by edited

codeberg.org/Serroda/fluid-tile

I was recently using Gnome with Pop OS and decided to switch to CachyOS with KDE, as I had seen that it was one of the best in terms of customization. But when using KDE, I realized that I was missing something that Pop OS implemented by default, which was the tiling system

So I decided to do some research and see if I could implement a solution that would suit my workflow, and that’s how “Fluid tile” was born

Fluid tile is a script for kwin that manages windows by adapting to the custom mosaic (Super + T). You can also configure it to your liking:

  • Maximize or not maximize the window when it opens

  • Maximize or not maximize the last window on the virtual desktop when it closes

  • Automatically create new virtual desktops

  • Remove empty virtual desktops

  • Blacklist apps that you don’t want the script to apply to

I’d like you to take a look and tell me what you think or any bugs you find. Thank you

WORKFLOW (How it works)

When a window is opened, it is expanded by default, if another window is opened and there is space the new window is moved to the widest layout, If there are other layouts with the same size, the one closest to the top left corner of the desktop will take priority. When a window is closing, If only one window remains on the desktop, It will be expanded. Finally, if the desktop is empty, remove the desktop.

Would this work on Fedora’s atomic spins and forks running KDE Plasma?

I run Bazzite, which is downstream of silverblue.

Also, out of curiosity… Would this work on KDE OS?

Hi, this script will only work if the window manager is KWin. Fedora A’s atomic spins uses Sway and the forks should work if you use Kwin by default

KDE Linux uses KWin by default

Bazzite uses Kwin, so it should work, right? Even if it’s atomic / semi-immutable.

Yeah of course, try installing the script from the KDE settings using the Get New button. Instructions

Yesterday I tried it on Aurora, I couldn’t download a single kwin script, that’s on them. Today I tried Fluid Tile on Bazzite, works like a charm. Great work!

Thanks mate, one question. Aurora won’t let you install any kwin scripts? How are you trying to install the scripts? Manual or with Get New button?

Get new button, works on Bazzite. Tomorrow I’ll try again on Aurora.

Hey, I’ve been using it for about a week on Bazzite and I’m really enjoying it. Great work.

Thanks mate, If you miss any feature or have any problem, let me know

I am actually very interested in a scrolling window tiling, like:

  • PaperWM (Gnome Extension) (2nd best example)
  • Karousel (Kwin Script)
  • Niri (wayland compositor wm) (best example)

Would it be viable to spin up something similar ?

Hi mate, your proposal is very interesting and it’s pretty cool but it would involve writing my own tiling engine, the idea of Fluid tile is that it continues to work with native KWin tile manager

Right now I’m working on:
- Wiki to resolve doubts
- Create your own pre custom layout when a virtual desktop is created
- Do not leave blank spaces when arranging windows, this will be done by extending existing windows
- New UI when you move windows with the mouse, to put them on the tiles, similar to KZones

When I have more time I will add more things

Yeah, I figured it would be a colossal effort, but asked anyways in case I was wrong in my assumption.

Why don’t you use those alternatives instead of Fluid tile if you want scroll mode?

  • I’m a happy Bazzite user, so I can’t use Niri, also I fear about gaming with their compositor.
  • I prefer KDE over Gnome, so PaperWM is out.
  • Karousel needs much more work before it becomes as usable as the alternatives.







Looks sick! I’ll try it out when I get home.

Thank you, feel free to tell me your opinion



"These options did not add any real value" made me smile. That’s the Windows 11 tagline!


Oh snap! Didn’t know this existed. Definitely want to try this out when I get back to my PC

Try it and let me know what you think



how is this one different from krohnkite and karousel?

Fluid tile does not replace the KWin tiling system, just adds more auto-tiling features. Krohnkrite and Karousel replace the current KWin tiling system

Fluid tile works with KWin tile editor (Meta + T shortcut), this allows better integration with KWin without needing to create another tile editor as is the case in Krohnkite, additionally, you can use the shortcuts that come with KDE by default to move windows, and expands functionalities such as changing the tile layout with shortcuts, etc..

The idea is to adapt to the KWin tiling system, not replace it


sounds a lot like polonium. didnt work out great there but it could’ve just been a bad implementation. I’ll have to give fluid tile a try.

I haven’t tried polonium, so I don’t know how it works. If you have any problems or questions, don’t hesitate to ask me

it had kinda the same idea of working with kwin instead of against it but it just worked worse than other options. iirc it got abandoned bc nobody was interested anymore once krohnkite was revived. yours also seems kinda similar to mousetiler.

Mouse Tiler has the same problem as the other options: it replaces the KWin system.

I recently added a compact mode for user interfaces similar to Mouse Tiler or Kzones, for those who don’t want the overlay to take up the entire screen.

The fact is that they all follow the same pattern, replacing the KWin system, and I don’t think that’s the best option. In the end, conflicts will always arise because you’ll always be fixing incompatibility issues with two systems that are fighting each other.

what’s the issue though? the existing system in plasma is already so out of the way its barely useful, so it makes sense to replace it with a better system and just ignore it. not that you shouldnt be doing what you’re doing, I just dont get why.








Woah, I gotta try this, dynamic tiling (and the related shortcuts/interactions) was the only thing that pushed me away from kde to hyprland. Great stuff, thank you!
