VulkanMakie?

[VarLad]

Any chance if we'll get a VulkanMakie? Many users are facing trouble with OpenGL as backend... Installation not working and other issues. Also, Vulcan will give a better performance and is cross-platform too.

[SimonDanisch]

Those installation errors are a very specific issue with Julia + some very specific linux + intel/amd drivers - nvidia seems to be without any issue.
I hope they'll get fixed - Before those got introduced, OpenGL support has been pretty stable.
Believe me, Vulkan will in no way make this easier, since it will likely bring many other new issues - and the llvm problem that is behind those intel/amd driver issues likely will also happen for Vulkan, since it builds upon the same tech stack for those vendors.

Regardless, a Vulkan backend is still planned, although with low priority.
I hope to switch soon to some abstractions, that will work across WebGL, OpenGL & Vulkan and at that point it should just be a matter of implementing the abstraction for Vulkan.

[VarLad]

I am using Nvidia though...
Glad to know the Vulcan backend is in your list.
Its low priority so I'm guessing it'll take a lot of time...?

[SimonDanisch]

Yeah likely... What problems did you have with nvidia?

[VarLad]

The building of GLMakie failed because it couldn't find drivers in the dri folder. There're dozens of those issues! I did resolve the issue, but the second plot made my system go slow motion. It felt like it was not using my GPU at all. I closed and reopened julia and it stopped plotting due to some issue in libGL. I did post the issues but it was closed immediately marked as duplicate
There're dozens of complains over GLMakie, either directly or mentioned, and they're the exact same complain.
Also, when I ran ]test GLFW, it gave the same error as above, leading me to believe there's some problem with that package.

[VarLad]

Makie is an awesome production level package and it's almost in pure Julia. But it must even run to allow the users to even complete the tutorial. Whats the status on GRMakie? Will it use the GPU and will it require opengl dependencies?

[mkborregaard]

GRMakie does not use the GPU and does not require openGL. Check also CairoMakie.

[VarLad]

Does CairoMakie make use of the GPU？

[mkborregaard]

No, only GLMakie does that.

[VarLad]

Thanks for the information
Cairo is really slow.
I hope the Vulkan backend comes along soon. I'll keep installing Makie and updating GLFW from time to time, hoping for the issue of GLMakie to get resolved in one of the updates！

[mkborregaard]

You are still very vague about what the issues actually are. I have no problems with GlMakie myself.

[VarLad]

#699

[VarLad]

There are many solutions as many people got this exact same problem and opened issues.
None of the solutions worked for me！
The exact same error as #699 showed up when I ran ]test GLFW too
Which led me to think if we'll get another backend which can use the GPU. For cross-platform, Vulkan was the first thing which came to my mind

[mkborregaard]

Ah OK thanks. And you upgraded your nvidia drivers?

[VarLad]

All my drivers are already up to date！
Is there something you'd like me to type into the terminal and post the result here？
Fedora 32 64-bit NVIDIA GEFORCE MX130, intel i5, intel UHD

[SimonDanisch]

Yeah, so that's not an NVIDIA problem as I pointed out - NVIDIA (almost) never made any problems as far as I'm informed...

That's exactly the INTEL + Linux problem I'm talking about, and I'm 99% sure, that Vulkan will show exactly the same issue ;)

Did you try:
#630 (comment)

Btw, this is a new issue (last couple of months) coming from some Intel/AMD & Linux & Julia updates, that I can absolutely do nothing about, which is pretty annoying...

You should complain to Linux GPU support ;)

[VarLad]

I solved it by (on Fedora/GNOME)

1. Right-click on your Terminal/Editor/IDE and click on "Launch using Dedicated graphics card"
2. (in your terminal) DRI_PRIME=1 Editor/IDE
3. (in your terminal) DRI_PRIME=1 Terminal/julia IS A BAD IDEA
   If you want to, the above solution can be put to the Troubleshooting section.
   Anyway, thanks a lot for helping and listening @SimonDanisch and @mkborregaard! My issue is officially resolved!

[VarLad]

Also, StatsMakie downgrades my Optim.jl and its dependencies heavily.
Should I open a new issue for it? It looks like a problem with tags, if so, it could be resolved quickly...

[SimonDanisch]

StatsMakie is deprecated in favor of AlgebraOfGraphics.jl!

[VarLad]

Kindly update the docs then！

[VarLad]

Also, AlgebraOfGraphics.jl is a part of Makie too？

[jkrumbiegel]

No it is a separate package, as statsmakie was

[SimonDanisch]

We updated the docs, I'll check if it's already deployed!
