Couldn't find matching GLX visual

[divisonofficer]

I'm using Ubuntu 22.04 on AMD64 platform with NVIDIA RTX 4060 (laptop). OpenGL version is 4.5 Messa 23.2.1-1ubuntu3.1~22.04.2

When i try to run ''mapping_vis.py'' via x11 connection,

Traceback (most recent call last):
  File "/home/cglab/project/spectacularAI-example/python/oak/mapping_visu.py", line 124, in <module>
    visualizer.run()

pygame.error: Coudn't find matcing GLX visual

Looks like that "GL_MULTISAMPLEBUFFERS" and "GL_MULTISAMPLESAMPLES" options cause problem.
Could you update the core sdk that user manually disdable that option?

Hey, thanks for letting us know. The source code for the Python visualizer is available here. Could you try if removing the multisampling fixes the issue for you?

Also make sure your OpenGL drivers are correctly configured. "Mesa" drivers in use sounds like an issue in your setup. If you install the Nvidia driver and check that e.g., glxgears works (shows animated gears), then the SDK is likely to work too.
