Jimster, it reminds me of this thread -
I find myself in a rather unexpected situation: It looks like the nvidia-driver-535 has removed itself automatically, for the second time already.
After rebooting the computer, after it was working fine, I now get messages that there are issues with the GPU drivers. When I want to check with nvidia-smi I get the following:
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Is this normal?…
have you tried reverting to an older driver to see if it helps? and though it’s not a startup problem, here’s a troubleshooting topic from the doc that you could check out in case it’s somehow related:
https://docs.omniverse.nvidia.com/dev-guide/latest/linux-troubleshooting.html#q5-startup-failure-with-vkresult-error-device-lost
there’s another thread where reverting to driver 525 alleviated the crashing for version 2022.2.1 (this was a few versions ago, so take that into consideration):
Hi y-mizomoto, sorry to hear you have issues.
535 driver series are not currently fully compatible with Omniverse applications. In the near future, we should be able to support them, once technical requirement page is updated to specify that.
Since you are on a laptop GPU, could you please try driver 525.125.06 that should be compatible:
It would be nice if you could provide the .log file as well (Settings → logs location, then Kit/[app-name]/[version]/*.log). Thanks
