GLFW Issue on Ubuntu 24.04

[david-dorf]

Intro

Hi!

I am a robotics engineer at Triton Systems and I use MuJoCo for simulation.

My setup

MuJoCo 3.2.7 on PyPi (Python), AMD64, Ubuntu 24.04

What's happening? What did you expect?

Running within a Bazel module:

INFO: Running command line: bazel-bin/mujoco_py
/home/david/.cache/bazel/_bazel_david/f695e6f26414630bc7daef67dcbe0426/execroot/_main/bazel-out/k8-fastbuild/bin/mujoco_py.runfiles/.mujoco_py.venv/lib/python3.12/site-packages/glfw/init.py:917: GLFWError: (65548) b'Wayland: The platform does not provide the window position'
warnings.warn(message, GLFWError)

Attempts to import GLFW directly haven't worked to eliminate this from popping up every time the viewer is opened.

Steps for reproduction

1. Run the code below.
2. Get the warning message.

Minimal model for reproduction

Shouldn't need this if you import the robot_descriptions package as follows

Code required for reproduction

import time
import mujoco
import mujoco.viewer
from robot_descriptions.loaders.mujoco import load_robot_description


model = load_robot_description("panda_mj_description")
data = mujoco.MjData(model)

with mujoco.viewer.launch_passive(model, data) as viewer:
    try:
        while viewer.is_running():
            step_start = time.time()
            mujoco.mj_step(model, data)
            with viewer.lock():
                viewer.opt.flags[mujoco.mjtVisFlag.mjVIS_CONTACTPOINT] = int(data.time % 2)
            viewer.sync()
            time_until_next_step = model.opt.timestep - (time.time() - step_start)
            if time_until_next_step > 0:
                time.sleep(time_until_next_step)
    except KeyboardInterrupt:
        pass

Confirmations

• I searched the latest documentation thoroughly before posting.
• I searched previous Issues and Discussions, I am certain this has not been raised before.
