Question about running on Ubuntu22.04

[RobinWitch]

Hello,
I am trying to use this on Ubuntu 22.04 via VNC(TigerVNC) with a 4090 GPU. However, When I run python examples/joint_monkey.py, I am encountering a strange problem:

Importing module 'gym_38' (/mnt/data/cbh/Eureka/isaacgym/python/isaacgym/_bindings/linux-x86_64/gym_38.so)
Setting GYM_USD_PLUG_INFO_PATH to /mnt/data/cbh/Eureka/isaacgym/python/isaacgym/_bindings/linux-x86_64/usd/plugInfo.json

Segmentation fault (core dumped)

Interestingly, I tested this on another server with Ubuntu 20.04 and a 3090 GPU using the same VNC server program((TigerVNC)), and it worked successfully. Both computers are cloud servers. I wonder how I can solve this problem.

Any help would be greatly appreciated.

Hi, I have the same problem, how did you fix it. Thx☺️

I use vnc to visualize screen on remote server, in fact I mistake my vncserver installed in remote server, I use TightVNC instead of TigerVNC.

I uninstall TightVNC and install TigerVNC, the error then has been solved.

Thx, I run my program on TurboVNC, it doesn't have GPU acceleration, but the Isaay Gym maybe neet it, I'll try TigerVNC.
