I have a similar error:

Does anyone know where the "WindowlessContext: Unable to create windowless context" issue might come from. I reinstalled the NVIDIA drivers and that did not work.

Thanks in advance

I had not restarted my system after installing CUDA Toolkit. Today, by accident, I restarted, and now example.py inside habitat-sim is working (but not the example.py in habitat-api)!
These are the steps I've took to install cuda toolkit 12.4 on Ubuntu 22:

Base Installer:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/12.4.0/local_installers/cuda-repo-ubuntu2204-12-4-local_12.4.0-550.54.14-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2204-12-4-local_12.4.0-550.54.14-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2204-12-4-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get updatesudo apt-get -y install cuda-toolkit-12-4

Driver Installer

sudo apt-get install -y cuda-drivers

Hope helps others.
