No video output with onboard adapter


  • After removing my physical nvidia graphics card and connecting the HMDI cable to my onboard adapter there is no video output. Looking in xcp-ng center -> host -> GPU i see "GPU configuration and monitoring is disabled, because there are no GPUs available on this host." and in XO shows blank/empty value.

    • Motherboard: ASrock Fatality B450 (link)
    • CPU: AMD Ryzen 7 2700X
    • xcp-ng: 8.1.0
    • xcp-ng center: 20.04.00

    The isn't a very big issue because all of the management is done thru ssh, xcp-center or xo. But knowing i can't fallback on the possibility on managing the machine physically doesn't feel good. Is there a way in xcp to rescan its hardware, download or load the default onboard video drivers?

    The Ryzen 7 2700X is not equipped with a GPU. IIRC only G-suffixed Ryzen are equipped with one.


  • :SlapinFace: should have know that but didn't double check it.. anyways thanks!
