SYS-220GP-TNR ; This specific server has a deffective GPU. It takes a long time to boot and 50% percent of the time it doesn't boot to my linux (mint) because the Nouveau driver fails to connect to the card. I have taken another gpu card from another sys-220gp-tnr and it works fine.
FYI, There are many customers using not certified OS in their systems. That may be ok as soon as system can run. The only issue is about the GPU driver. The open source driver doesn’t guarantee that it will work with stability and customer has to run on their own risk. Also, Checked below link, but no LINK MINT driver is available from NVIDIA. https://www.nvidia.com/en-us/drivers/
