2 years ago Thanks for filing! From what I can tell Thinkpad X220 has an Intel 3000 chipset, which does not support Vulkan.
The OpenGL fallback should work, however the gpu/ sample currently has a bug where it's not using it. You can still try it out, though, in the other gpu-dawn/ sample like this:
cd mach/gpu-dawn/
GPU_BACKEND=opengl zig build run-dawn-exampleI'd be curious to hear if that works for you!

2 years ago This is what I get running the above commands. Looks like its still trying to use vulkan though?

I think you would get this by installing the latest mesa version on your system, but if not unfortunately we'd be out of luck here - device may just be too old.
You could check by looking at the output of glxinfo on your system (you may need to install a mesa-utils package)

2 years ago Alright, I'm pretty sure the video card is just too old at this point. Thanks for trying anyway!

2 years ago I appreciate you filing the issue regardless!
I tried to run the GPU example on my Thinkpad X220 laptop, but I got this error:
(I'm running Arch Linux with Sway)
I'm guessing my laptop is either unsupported (it is pretty old) or I don't understand how the OpenGL fallback is supposed to work. I'll probably just use my desktop for now.
