OS: Fedora 39 KDE Spin
KDE Version: 5.27.10
Kando version: 0.4.0 (also tested 0.3.0)

Hello, thanks for your awesome work on this project.

I've been using Kando since version 0.3.0 in KDE Plasma X11 and it works amazingly well.

Unfortunately under Plasma Wayland it has a couple of issues for me:

• The keyboard shortcut to open the menu does not work, despite clicking on "OK" when the Remote desktop portal prompt pops up to authorize Kando for keyboard input

• Right clicking on the Kando icon in the tray to open the menu works 25% of the time: if I try to open the Kando menu twice in a row nothing happens, I have to wait 30 seconds or more to have it open again, and sometimes not even that works.

I tried to use the "kando --menu "Prototype Menu"" command to open it, but it works reliably only if I run it in an open terminal window; if I try to run it as an application shortcut command (or if I put it in a shell script file and try to run it without a terminal open) it exhibits the same erratic behaviour as right-clicking on the icon.

It seems to open more reliably when a window is open on the desktop.

The current workaround I use in Wayland is to run the Kando command in a shell script from a desktop shortcut with the option "Terminal=true". This way I have a terminal window appearing briefly before the menu, but it opens every time.

If you need any log or other kinds of debug output I will be happy to provide them.

Thanks!

kando 0.4 just testing prelease build

trying to use the "Tile Left/Right" items in the demo menu is failing. config file shows its trying to send Meta+LeftArrow, i tried changing it to Super and also Win but none of them work to send

pressing Win+Left on my keyboard does in fact tile left

same problem occurs with "Toggle Maximize", ie Win+Up, tried all combinations

So I tried kando in three ways, firstly from the releases tab where trying to open kando by double clicking or just using ./kando command works but does nothing (not saying that the menu does nothing, but the menu or anything else doesn't appear).
Nor is there any error.

Secondly I tried the npm install then npm start and same result.

Lastly tried AUR and again using the command did nothing and the menu didn't appear after ctrl + space.

(TBH, I feel like this might be a some dumb mistake I did or I probably forgot some dependency so sorry in advance)

Hi, friend!
Do I understand correctly that at the moment, even if I configure a radial menu via menus.json, it will not be able to launch/execute the necessary commands?
Because now, I only see the appearance setting.

This is an unsupported combination! Kando will not work here :(

Does kando work only on Wayland ?

would be cool if we have modes to (un)check on an individual basis, e.g. i mastered my media pie-menu, so i don't have to think much about selecting it... although the key to access that menu is the same i use to do backup/power operations (they are in different sub-menus) and those aren't mastered to the point that i could use it with the "hover mode"

as a bonus, maybe the more user uses a menu, the app can suggest at some point a lower threshold or even activating the "hover mode"? ¶ modifying anything should reset the variable...

This should be done for the minimal working prototype. On Wayland, this also includes multi-cursor support.

I am trying to install Kando on Windows 11. The launch screen starts, animates for a couple of seconds and then closes.

Update: I managed to install it now, after trying a couple of times. But when I start it I get the following message:

Kando failed to start.
Please check the console for more info

I'm unsure how to find the console message however.

This is quite an impressive project and I really love this😊. Now I am trying this out on my laptop with hyprland. There seems to be some problems.
Here is the screenshot to show the problem.

First, I am using an external monitor(4K) together with the one build-in (2.8K). When I call the menu out on my external monitor, it seems that it just takes up part of the area of the screen, not the full screen.

Second, it seems that the panel of the menu just look through anything behind it straightly to the wallpaper rather than floating over the windows behind it. (I am not sure whether the transparency is something do to with my hyprland config, anyway I just wonder how to change this)

By the way, I am wondering if there is a way to close the menu just through the mouse, like the right button or something? I have already bind the trigger to the side bar of it and I want everything to be done with my mouse.

Hello, first of all well done for this amazing work! I strongly believe that the future of the Linux world lies in the development of desktop environment-agnostic software, and your work serves as a true inspiration.

I was trying to run kando on Ubuntu 23.04 and Gnome on Wayland. Unfortunately I get the following error when executing npm start:

Am I missing something? These are some information that you may find useful:

1. The XDG_CURRENT_DESKTOP environment variable is set as ubuntu:GNOME
2. I have installed the gnome extension (GNOME Shell Integration for Kando), then restarted Gnome and enabled the extension. It correctly shows as enabled

If you need any other information I'll be glad to provide them to you.
Thank you!

Hello, each I run the app there's info circle with 5 videos inside even though nothing is visible (I mean nothing from kando at all) they are all played and decoded!

And this is without gpu accel on 8 core cpu

There should be a quick visual introduction in the sidebar.

Basically the same request as this, in the Fly-Pie issue tracker
figured I'd basically ask again, since this is a brand new app separate from fly-pie that's still early dev.

After npm run package, the binary I get does not run due to SIGSEV (segmentation fault). This generally means the binary is built for glibc. I'm on Void Linux musl edition so I need it to build for musl.

Hi, curently kando try to look for ctl+space, idealy the keybind should be manage by the WM and kando.

Is there a docs that explains how to customize Kando nodes with images on each circle and the commands triggered by clicking on each one of them?

Furthermore, in the future there will be the chance to import in Kando the exported configuration of FlyPie?

Hello, currently if the text set as "name" for a node is too long it can extend past the center node circle.
Will there be a way to change the font size of the text for these cases ?

It would be awesome if it would be possible to control kando fully using only keyboad and no mouse involved. It can be useful in coding and other activities where one dosen't want to interact with mouse.

rofi like applications can be used but the versatile nature of kando, its looks, its animation, really hope it wold be possible.

From user side i can only think of this , one key to activate kando, 8-keys for directional navigation, 2-keys to go to previous/forwad in pie menu.

This is required for a minimal working prototype. There should be a button in the menu which simulates for instance Ctrl+C.

Hi, it's me again! I am now binding a new button to call out specific menu upon specific apps, along with another button to call out the global menu, which is really cool.
Now I want to use the GUI to adjust the new menu, but I can't find it anywhere in the GUI. So this is still unimplemented or I am missing something?
Still Hyprland, btw.

Have an option to make it so that moving mouse cursor certain distance away from the centre is automatically considered a confirmation of selected option.
So that we can move through the menu hierarchy without clicking.
Of course have the option where user can define this auto-confirm distance.

Disregard, this is already implemented as Turbo Mode (achieved by keeping Ctrl pressed while moving the cursor)

For the minimal working prototype, we need to check the host OS, whether we are on Wayland or X11 and the desktop environment.

Hey @Schneegans
currently I see that, for starting Kando, the user needs to run an executable that start a NodeJS server.

Instead of this, what do you think if Kando is used as service by running it using systemd or init? Because having a running NodeJS could be heavier than running Kando only as service. In this case the user needs only to run:

sudo systemctl enable kando

and at each reboot, kando is automatically run without the call of the executable (and could it prevent the usage of NodeJS?).

Let me know ^^

just downloaded this to test, also downloaded your demo menu from youtube, none of the hotkey shortcuts work. am i doing something wrong? also tried running the menu as administrator and that didnt work either

Please check the console for more information on Windows 11, tried the 0.2.0 version same issue as well.

I know that there are plans to implement application dependent menus, but I think it would also be nice to add support for application-title dependent menus. That is to say different menus depending on the title of the focused program window. For example, this would be helpful for having different menus depending on the current website you are on(such as google, youtube, gmail, etc.)

If implemented, the title detection could have different options where the text you configure has to either match exactly, show at the start, or show at the end of the focused window's title.

Hey,

I've followed the instructions to download Kando, specifically downloading a release and executing the kando binary. However upon binding kando:prototype_trigger to alt + space in my Hyprland config, the radial menu does not appear.

If I manually execute ./kando --menu "Prototype Menu" then the menu is rendered and functions as expected [1]. Looking at the Hyprland logs, I can confirm it is picking up on my keybinds because it outputs Keybind triggered, calling dispatcher (8, , 32) when I press alt + space.

Therefore I'm inclined to think this is some type of issue within Kando that isn't properly observing my keybinds, is there some way to enable verbose logging at the Kando level? Which I suspect might help narrow it down (I'm happy to build from source if required).

Is it possible to add instructions on README about building from source for Linux (I'm using Arch Linux but the instructions should be the same)?

A custom backend for wlroots would add support for compositors such as Hyprland. Implementing such a backend will be not exactly easy, but it should be possible. If you have some JavaScript and C++ knowledge, I would greatly appreciate a contribution here!

Here are some pointers:

• First, a new class implementing the Backend interface must be created. It could be in src/main/backends/linux/wlroots. The X11 backend could provide some inspiration. In the beginning, most methods can use some kind of dummy implementation.
• Then, the new backend must be instantiated in this file. For instance, if the compositor is Hyprland.
• Finally, all the methods of the backend need to be implemented. As wlroots implements a lot of cool wayland protocols, this should be possible.
• I once tried using a wayland protocol for KDE in Kando. It turned out to be not necessary, but I kept the code around for future reference. I think that this could be implemented in a similar fashion.

Hi, thousand thanks for your great Fly-Pie extension. I tested it yesterday in a Qemu hosted Ubuntu and would love to see it available for my KDE desktop!

I just cloned this repo and tried to follow the introduction. It did'nt work work out of the box as the following packages were missing on Kubuntu 23.04, X11:

libx11-dev libxss-dev xdotool

With these installed it worked flawlessly ❤️ maybe you could update the README to inform the user about potentially missing packages. Thanks!
