[Bug]: own_window_type desktop rendering

[QkiZMR]

What happened?

When own_window_type = "desktop" is used, conky is rendered a few times in the same place, causing a strange view and a black background.

When I set own_window_type = "normal", Conky is displayed normally, but shows only on one virtual desktop.

Version

1.22.2

Which OS/distro are you seeing the problem on?

Ubuntu

Are you using Wayland or X11 with Ubuntu?

• Behavior feels like like Wayland - in which case I'd close the issue (expected behavior), but I can't really tell.

Once you tell me, I can give you more detailed explanation and offer solutions.

[QkiZMR]

Wayland on KDE

[Caellian]

Ok so:

• Wayland doesn't support sticky windows (same window on multiple outputs/virtual displays/etc.). We can get around this in future by creating multiple windows, but that's not supported yet (known limitation).
• KDE handles XWayland very well but it's still limited in what it can do. Black background issue is one of the examples.

I suggest you try using out_to_x11 = false amd out_to_wayland = true with the latest main beanch and see whether conky works well-enough for you this way (won't be shown on multiple virtual displays no matter what atm).

own_window_type and own_window_hints only work because KDE has great backwards compatibility with X11 applications, but shouldn't be used in wayland mode (they're ignored with out_to_wayland)

[QkiZMR]

I compiled conky on the main branch, and run with my config and suggested options. Now Conky doesn't appear at all. Here is how it looks from the command line:

Last message repeats itself endlessly.

[Caellian]

You need to build conky with:

cmake -S . -B build --fresh -DBUILD_WAYLAND=ON -DBUILD_LUA_CAIRO=ON
cmake --build build
sudo cmake --install build

It's missing Lua bindings for Cairo currently. There might be some other options you want enabled, I suggest you use ccmake/cmake-gui to configure it so it does exactly what you need (see wiki for details). Note that imlib2 doesn't work on Wayland as it's X11-specific library.

The cairo module not found error is unrelated to your original issue and is just a missing install step. After building, you need to run:

 sudo cmake --install build

You're missing the lua cairo so file which is what's causing module 'cairo' not found error. Logs show that Lua checks in path cmake installs to on Ubuntu.

Now I'm able to run. It looks like Conky with window rules set in KDE system settings that force Conky to display on all virtual desktops. But this creates another problem, which I posted here.

So I think that I stick to the version from Ubuntu repositories and enable KDE window rules to have the same effect.

You're running with XWayland. But I think KDE actually handles this extremely well (actually listens to window type and hints).
