Both things appear to enable my machine to suspend and wake like clockwork. So, use the default kernel driver callback for handling the nvidia card’s suspend and hibernate, and PreserveVideoMemoryAllocations=0 or enable the nvidia systemd services for hibernate and suspend (that you mention) and set the above param to 1. ![]() ![]() This changes the default video memory save/restore strategy to save and restore all video memory allocations. It is not used by default, but can be taken advantage of by configuring the system as described in this chapter.Īdditionally, to unlock the full functionality of the interface, the NVIDIA Linux kernel module nvidia.ko needs to be loaded with the NVreg_PreserveVideoMemoryAllocations=1 module parameter. This interface is still considered experimental. To better support power management with these types of applications, the NVIDIA Linux driver provides a custom power management interface intended for integration with system management tools like systemd. If I were to venture a guess, I would say the problem begins with NVreg_PreserveVideoMemoryAllocations being set from 0 to 1, for it seems to be part of the Sudo dnf install xorg-x11-drv-nvidia-devel Sudo dnf install xorg-x11-drv-nvidia-cuda Ora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm Sudo dnf install $(rpm -E %fedora).noarch.rpm The nvidia drivers were initially installed via Please refer to the 'Configuring Power Management Support' section >Īug 21 18:56:04 feds kernel: PM: pci_pm_suspend(): nv_pmops_suspend+0x0/0x20 returns -5Īug 21 18:56:04 feds kernel: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -5Īug 21 18:56:04 feds kernel: nvidia 0000:05:00.0: PM: failed to suspend async: error -5` System Power Management attempted without driver procfs suspend interface.

It has always worked prior to today’s update. The screen blinks once or twice and it seems as if it’s going to suspend but then doesn’t. Today I updated the system(Rydesktop) which I do once or twice a week and it fetched among other things newer nvidia drivers, NVIDIA 470.63.01 to be exact and after a reboot the machine will not suspend. Hi, I’ve been running Fedora 34 KDE for a couple of months with a Nvidia RTX 2060 and the proprietary nvidia driver.
