Gray viewport in Create GUI with Linux / GeForce RTX 3060 / driver 460.80

When I launch Omniverse Create everything looks as expected, except the viewport is gray, and no scene content is rendered.

Different versions behave slightly differently:

  • With the standard launcher, the logs show Driver Version: 0.0, but with the singlegpu launcher the driver is correctly identified. In both cases the viewport is blank gray.
  • The Hydra Storm version works as expected with scene elements appearing in the viewport.
  • The iray version crashes with a segfault before it’s able to open the GUI at all.

Comparing the hdstorm (working) and singlegpu (blank viewport) versions,

Both logs contain a lot of the same this warnings, including:

[Warning] [omni.ext.plugin] [ext: omni.kit.window.viewport-0.0.0] '/home/x/.local/share/ov/pkg/create-2021.1.1/_build/kit_release/_build/linux-x86_64/release/plugins/rtx/rtx.reshade.plugin' in '[[native.plugin]]' was not found.

The hdstorm version shows this error, although it still works fine:

[Error] [omni.kit.window.viewport.plugin] Failed to find suitable scene renderer

The singlegpu version does not show that error, but it does dump the following errors not present in the hdstorm logs:

2021-07-05 19:45:26 [1,412ms] [Warning] [omni.ext.plugin] [ext: omni.kit.editor-full-0.0.0] '/home/jmp/.local/share/ov/pkg/create-2021.1.1/_build/kit_release/_build/linux-x86_64/release/plugins/rtx/rtx.reshade.plugin' in '[[native.plugin]]' was not found.

Update: the topic discussed in View port Screen gray - #18 by mirice got me on the right track. It seems that something about the way my home directory is mounted was preventing the cache from working correctly. It wasn’t a permission issue in my case, though. The error I found looked like:

[Error] [carb] File copy failed: '/home/x/.local/share/ov/pkg/create-2021.1.1/_build/kit_release/_build/linux-x86_64/release/cache/Kit/100.3/528-c8003e0d-release/shadercache/41a2c6f399b44bd63ed18fef9ea0ced6.v.desc' -> '/home/x/.cache/ov/Kit/100.3/528-c8003e0d-release/shadercache/41a2c6f399b44bd63ed18fef9ea0ced6.v.desc' (Invalid argument)

Uninstalling using the cleanup tool, and re-installing with a different cache path – on another filesystem – did the trick.
