But the window still opens, im on arch with wayland

You need to install vulkan drivers

#

https://wiki.archlinux.org/title/Vulkan

Vulkan

#

Don't think this is related to Vulkan specifically, as it fails with OpenGL too, so I think this is more of an Integrated GPU driver issue instead

#

It also doesn't say from the logs on which platform @mossy lintel is from

running on a laptop without any gpu

#

ah didnt see ill try this anyway asap

#

is there a way to get more detailed logs?

mossy lintel running on a laptop without any gpu

Which OS?

mossy lintel is there a way to get more detailed logs?

RUST_LOG=debug cargo run

im on arch linux with wayland

mossy lintel Apr 2, 2024, 10:10 AM

#

fresh nymph `RUST_LOG=debug cargo run`

floods my logs every frame

#

can vulkan run on an integrated gpu?

fresh nymph Apr 2, 2024, 10:14 AM

#

You can change the levels for each module, in this case it's probably wgpu and bevy_render, so you can do RUST_LOG=debug,wgpu=info,bevy_render=info cargo run

#

mossy lintel can vulkan run on an integrated gpu?

If the integrated GPU supports it, yeah

#

If you're on Arch, then yeah you probably forgot to install MESA and/or the Nouveau graphics driver

#

-> https://wiki.archlinux.org/title/intel_graphics

Intel graphics

#

yes i definitly did not, didnt even know i need it

fresh nymph Apr 2, 2024, 10:16 AM

#

Most distros do automatic detection during install, and automatically install the right drivers for you, but I'm guessing Arch being Arch it doesn't since you have to manually configure your system

#

hm actually i had mesa installed

#

was already up to date

#

actualy in the logs it said i had mesa oof

#

name: "Mesa Intel(R) UHD Graphics (TGL GT2)"

#

well i guess this issue isnt that big of a deal as it runs

fresh nymph Apr 2, 2024, 10:21 AM

#

Quick search tells me this is a recent one too, and supports OpenGL 4.6 and Vulkan 1.3, so you should be fine

#

it's weird that it doesn't seem to load OpenGL correctly though

mossy lintel Apr 2, 2024, 10:21 AM

#

oddly, in the library speed2d i got "Invalid surface" in the latest versions

#

maybe its wgpu

fresh nymph Apr 2, 2024, 10:23 AM

#

ah but wait, I also misread the logs, it doesn't say it doesn't support it, it says that the SSAO plugin couldn't be loaded because of a missing specific OpenGL feature

#

You can try to install vulkan-intel to get Vulkan support on your system

mossy lintel Apr 2, 2024, 10:23 AM

#

whats SSAO?

fresh nymph Apr 2, 2024, 10:23 AM

#

SSAO is a shading technique that supplements shadows to get a more realistic appearance on surfaces that are close together

thank you!
