Not sure if it’s the same issue but I wasn’t getting display output after resume and even switching TTY didn’t fix it. I searched and searched and was about to give up when I turned to Copilot and asked it.
Answer was given right away in the first set of things to try. Much as we might grumble about AI taking jobs and whatnot, it got me past a wall of "I have the same issue"s and did a great job.
sudo systemctl enable --now nvidia-persistenced.service
Now it works for me. I do have to press a key after resume but that’s all.
