GLMakie

GLMakie is the native, desktop-based backend, and is the most feature-complete. It requires an OpenGL enabled graphics card with OpenGL version 3.3 or higher.

Special GLMakie Properties

Window Parameters

You can set parameters of the window with the function set_window_config! which only takes effect when opening a new window.

set_window_config!(;
    renderloop = renderloop,
    vsync = false,
    framerate = 30.0,
    float = false,
    pause_rendering = false,
    focus_on_show = false,
    decorated = true,
    title = "Makie"
)

Forcing Dedicated GPU Use In Linux

Normally the dedicated GPU is used for rendering. If instead an integrated GPU is used, one can tell Julia to use the dedicated GPU while launching julia as $ sudo DRI_PRIME=1 julia in the bash terminal.

Troubleshooting OpenGL

If you get any error loading GLMakie, it likely means, you don't have an OpenGL capable Graphic Card, or you don't have an OpenGL 3.3 capable driver installed. Note, that most GPUs, even 8 year old integrated ones, support OpenGL 3.3.

On Linux, you can find out your OpenGL version with: glxinfo | grep "OpenGL version"

If you're using an AMD or Intel gpu on linux, you may run into GLFW#198.

If you're on a headless server, you still need to install x-server and proper graphics drivers.

You can find a demo on how to set that up in this nextjournal article.

GLMakie's CI has no GPU, so you can also look at .github/workflows/glmakie.yaml for a working setup.

If none of these work for you, take a look at the other backends, which all work without a GPU.

If you get an error pointing to GLFW.jl, please look into the existing GLFW issues, and also google for those errors. This is then very likely something that needs fixing in the glfw c library or in the GPU drivers.

WSL setup or X-forwarding

From: Microsoft/WSL/issues/2855

WSL runs OpenGL alright, but it is not a supported scenario. From a clean Ubuntu install from the store do:

sudo apt install ubuntu-desktop mesa-utils
export DISPLAY=localhost:0
glxgears

On the Windows side:

  1. install VcXsrv

  2. choose multiple windows -> display 0 -> start no client -> disable native opengl

Troubleshooting:

1.) install: sudo apt-get install -y xorg-dev mesa-utils xvfb libgl1 freeglut3-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev libxext-dev

2.) WSL has some problems with passing through localhost, so one may need to use: export DISPLAY=192.168.178.31:0, with the local ip of the pcs network adapter, which runs VcXsrv

3.) One may need mv /opt/julia-1.5.2/lib/julia/libstdc++.so.6 /opt/julia-1.5.2/lib/julia/libcpp.backup, another form of GLFW#198
