I have the following problem:
Whenever I want to start Isaac Sim (from the omniverse launcher or commandline), I encounter the same behaviour. It hangs forever in the line [ext: omni.kit.renderer.init-0.0.0]. See Image below
I am using Ubuntu 20.04 and the version of Isaac Sim is the latest release 2022.2.1.
I already did a reboot and a re-installation of isaac sim, none of them helped me to overcome the problems.
Does anybody have an idead how to solve it?
Updated the driver to 525.85.05, but still not working.
@christof.schuetzenhoefer - Can you try instructions provided in this forum post and see if it helps resolve the issue? Isaac Sim recompiling ray tracing shaders every time it is opened
Hi, I cleared the shader cache, but the problem still persists.
Any other ideas?
Try uninstalling the current driver and remove the folders below if they exist:
Then install this latest driver:
Linux x64 (AMD64/EM64T) Display Driver | 525.89.02 | Linux 64-bit | NVIDIA
Okay, but in the docker I have no problem launching isaac sim. I guess the problem is somewhere else since in the docker the same vulkan files are used?
Are you able to run it successfully in a container on the same machine?
For 2022.2.1, we have a copy of the vulkan files in the correct place and it acts like a clean copy of Ubuntu.
However, on host, you may have upgraded from an older version of the drivers where the vulkan files in the previous version were not completely cleaned and may cause an issue with duplicate/old vulkan files.
Yes, I can run Isaac Sim on the same machine within docker successfully.
okay, how can I resolve this issue with the vulkan files?
Situation for me:
The folder for the vulkan library in “/etc/vulkan” was empty ( no json files ), but the folder in “/usr/share/vulkan” was with the correct files.
I can now launch Isaac Sim using the following steps:
remove /etc/vulkan folder
copy the files from /usr/share/vulkan to /etc/vulkan
