nvidia power management

Hello, I have recently experienced a resume failure with nvidia [1]. Upon deeper investigation, it turns out that PreserveVideoMemoryAllocations was enabled recently [2]. According to documentation [3] and to Arch Wiki [4], for this option to work, nvidia systemd units need to be enabled (nvidia-resume is not recommended by Arch). They are not on my machine: $ sudo systemctl status nvidia-suspend.service nvidia-resume.service nvidia-hibernate.service [sudo] hasło użytkownika julas: ○ nvidia-suspend.service - NVIDIA system suspend actions Loaded: loaded (/usr/lib/systemd/system/nvidia-suspend.service; disabled; vendor preset: disabled) Active: inactive (dead) ○ nvidia-resume.service - NVIDIA system resume actions Loaded: loaded (/usr/lib/systemd/system/nvidia-resume.service; disabled; vendor preset: disabled) Active: inactive (dead) ○ nvidia-hibernate.service - NVIDIA system hibernate actions Loaded: loaded (/usr/lib/systemd/system/nvidia-hibernate.service; disabled; vendor preset: disabled) Active: inactive (dead) I am not sure what Fedora's policy on enabling systemd units by default is, but it appears like either the systemd units need to be enabled or PreserveVideoMemoryAllocations should be rolled back. With nvidia-suspend and nvidia-hibernate enabled, my machine does suspend correctly again. With nvidia-resume enabled, it also does resume properly. Without it, machine resumes but the screen does not re-activate. Best regards, Julian [1] https://forums.developer.nvidia.com/t/occassional-failure-to-resume-pci-p...
