IsaacGym Setup: X Error of failed request: BadMatch

I need IsaacGym for a project and after having installed it I’m trying to run a few provided examples. However, when I run the command python, it starts running, launches an IsaacGym window, and instantly crashes. I want to run it on my laptop right now to get accustomed to IsaacGym, but I will be running any real simulations on a cluster later.

The error I’m getting is the following:

Importing module ‘gym_38’ (/home/user/isaac_ws/isaacgym/python/isaacgym/_bindings/linux-x86_64/
Setting GYM_USD_PLUG_INFO_PATH to /home/user/isaac_ws/isaacgym/python/isaacgym/_bindings/linux-x86_64/usd/plugInfo.json

I’m running this an on XPS 9500 2020 on Ubuntu 22.04 with a GTX 1650 Ti using driver 525.78.01 and CUDA version 12.0.

Any help would be appreciated.

have you solved this problem? I have the same issue. Thank you


Unfortunately I found no solution to this issue, and ended up installing Ubuntu 20.04 on a separate partition.

Thank you. Good to know it works fine on Ubuntu 20.04

did it work on ubuntu 20?

Yes, it did for me.

Thank you, it works well now.


Are you able to view the rendering for the simulation?
Asking cuz even I have a GTX 1650 Ti powered laptop and the Isaac Sim window keeps saying RTX loading and doesn’t render anything. ( Expected considering the min requirements include a RTX :( )

Just wanted to ask if were able to figure a way around this and make it work ?


Yes, I am using an XPS 15 with a 1650Ti and if I’m running in Ubuntu 20.04 I have no issues rendering(in 22.04 it would not work). You may be missing a dependency somewhere or don’t have your GPU enable? Try the command nvidia-smi to check if you’re using your Nvidia GPU or integrated graphics.

I had the same issue. The root problem is that Vulkan uses Intel graphics by default instead of my NVIDIA GPU.

export VK_ICD_FILENAMES="/usr/share/vulkan/icd.d/nvidia_icd.json"

This should solve the issue. I found the answer on this thread: Invalid pixelmap or window parameter · Issue #2232 · carla-simulator/carla · GitHub


Thank you! It works!
