Error: No suitable `wgpu::Adapter` found.

Hi and thanks a lot for binocle!

I just tried binocle on a Lenovo X220 running Arch Linux:

$ RUST_LOG=trace binocle /bin/ls

Is there anything I can do to debug this?

Thanks!

Looks like maybe you are missing some vulkan drivers? See https://wiki.archlinux.org/title/Vulkan

I'm on Arch as well and it works fine for me.

@sharkdp: Thanks, that was it.

Since I'm on Sandy Bridge and my "graphics card" acccording lspci | grep VGA is

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

I couldn't just install vulkan-intel since Vulkan is only supported since Ivy Bridge.

Instead of using vulkan-intel, I followed this advice and installed vulkan-swrast which made binocle run.

Unfortunately, binocle uses two cores all the time, without me interacting with the GUI.

But thanks again for helping out. 👍

Yeah, binocle is quite heavy on CPU usage. It's currently rendering the UI and the visualization in every frame.

But two cores full time?! For me it's one CPU at ~70%.

Is it still usable for you?

[sharkdp]

Ahh... swrast is the software rasterizer. That's probably why. That will make the UI quite laggy, I assume. It's rendering on the CPU instead of the GPU.

what wrong? why don't work?

pacman -S vulkan-swrast and all can be work

There have been some updates w.r.t. this in the latest version, so it might be worth checking out.
