Hi:
Recently, i tried to run example with"python play.py --task=anymal_c_flat", and got the message with this. And,the isaac gym window appears and then disappear.
For some reason i reinstalled my NVIDIA driver. I am new at siaac gym, and don’t know how to solve it successfully after trying .

I remove my environment——rlgpu, and rebuild it. But when i run python 1080_balls_of_solitude.py, i got this

Actually, When i run “python play.py --task=anymal_c_flat --headless”,it works! But, now I cannot use issacgym with GUI mode.
When i do vulkan-info , and vk-cube,i got this.

(rlgpu) dingle@dingle-HP-Z840-Workstation:~/legged_gym/legged_gym/scripts$ vulkaninfo
ERROR: [Loader Message] Code 0 : libGLX_nvidia.so.0: cannot open shared object file: No such file or directory

ERROR: [Loader Message] Code 0 : vkCreateInstance: Found no drivers!
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.

(rlgpu) dingle@dingle-HP-Z840-Workstation:~/legged_gym/legged_gym/scripts$ vkcube
vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extension.

Do you have a compatible Vulkan installable client driver (ICD) installed?
Please look at the Getting Started guide for additional information.

Is this the reason why I can’t use the GUI mode?

Hello, i met same problem as yours. Have you solved it yet?(for GPU Pipeline disabled problem) Can you show some details about the solution?

I have the same issue. After debugging, I found that the issue was actually due to the lack of Vulkan installation. The official Vulkan is more complete on Ubuntu 20.04, so if there are no special requirements, you can consider using Ubuntu 20.04. Otherwise, you may need to install Vulkan from source code.

I encountered the same issue mentioned earlier and would like to follow your suggestion to install Vulkan from the source code. I am using Ubuntu 22.04 and cannot switch to 20.04 to use the official Vulkan packages.

Could you provide more detailed instructions on how to install Vulkan from the source code specifically for Ubuntu 22.04?
