Well, I might try that but it’s a lot of work… there was a “guide” mentioning how to install drivers there Hardware HDR tonemapping still broken on 1.31.0.6654 - #200 by premikkoci
But by looking how to passthrough GPU to a docker instance, I also seen that at least on Ubuntu, there is dedicated headless drivers. Is there any equivalent on RHEL? Maybe it worth the try…
Another question: is there anything I can setup in my preferences file, I’ve seem the option “VaapiDriver=XXXX” is existing.
@ChuckPa if you have any answer to give me…
