I installed the chart on the cluster, but the desktop container has an error, see the log below:

Yeah, so this is probably related to an issue with automatically disabling hardware acceleration when no graphics card is present/passed through to the container. For now, you can set the environment variable DISABLE_HW_ACCEL to "true".

If that doesn't fix it, it might be helpful to see the rendered k8s resources, or your values overrides.

This seems even more likely now, looking at the environment variables set in the chart. A lot of these were hardcoded in to work with earlier versions of the desktop component, before it got smarter about auto-detecting things.
