I have an Nvidia K2220 on a new to me Z640 workstation and nvidia-suspend fails leaving a black screen and no obvious way to gracefully recover. I can ssh into the machine, but I can not find a way to reboot or poweroff due to nvidia-suspend. For now I disabled nvidia-suspend.service. Any ideas on why suspend is failing or at least how to recover without a hard reset?
I need to run cuda, so nouveau is not an option
Note. I have a laptop with an M2220 with the same driver and kernel and it suspends correctly
