NVIDIA Suspend fix

echo "options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=${TMP_PATH}" | sudo tee /etc/modprobe.d/nvidia-power-management.conf 

sudo install --mode 644 "${TMPL_PATH}/nvidia-suspend.service" /etc/systemd/system
sudo install --mode 644 "${TMPL_PATH}/nvidia-hibernate.service" /etc/systemd/system
sudo install --mode 644 "${TMPL_PATH}/nvidia-resume.service" /etc/systemd/system
sudo install "${TMPL_PATH}/nvidia" /lib/systemd/system-sleep
sudo install "${TMPL_PATH}/nvidia-sleep.sh" /usr/bin

sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-hibernate.service
sudo systemctl enable nvidia-resume.service

Initial tests, this works for me on Mint 22.2, Driver Version: 580.105.08 to get suspend working:
systemctl enable nvidia-suspend.service
systemctl enable nvidia-hibernate.service
systemctl enable nvidia-resume.service

my /etc/modprobe.d/nvidia-graphics-drivers-kms.conf:
options nvidia-drm modeset=1
options nvidia NVreg_PreserveVideoMemoryAllocations=0
options nvidia NVreg_TemporaryFilePath=/var/tmp

Fedora 43 Workstation
ThinkPad P16s Gen 2
6.18.6-200.fc43.x86_64
GNOME 49.3
GPU 1: NVIDIA RTX A500 Laptop GPU
GPU 2: Intel Iris Xe Graphics @ 1.50GHz [Integrated]

/etc/modeprobe.d/nvidia.conf:

# Disable Nvidia modesetting for hyprid graphics
options nvidia-drm modeset=0

# Enable dynamic power management
options nvidia NVreg_DynamicPowerManagement=0x02

# Disable GSP firmware (can cause issues on some laptops)
options nvidia NVreg_EnableGpuFirmware=0

# Preserve video memory allocations across suspend/resume
options nvidia NVreg_PreserveVideoMemoryAllocations=1

# Disable S0ix power management
options nvidia NVreg_EnableS0ixPowerManagement=0

I tried the systemctl enable nvidia commands but this never fixed my problem.

What worked for me was disabling USB and THunderbolt wake:

# Disable XHCI (USB)
echo XHCI | sudo tee /proc/acpi/wakeup

# Disable TXHC (Thunderbolt)
echo TXHC | sudo tee /proc/acpi/wakeup

# Verify both are disabled
cat /proc/acpi/wakeup | grep -E "XHCI|TXHC"

Both should be *disabled - I have to use my laptop keyboard/trackpad to resume but I am fine with that so keep it in mind if you are not using a laptop.

I think that something was sending wake signals hence why I disabled those.

To make it permanent create a service for it:

/etc/systemd/system/disable-usb-wakeup.service:

[Unit]
Description=Disable USB wakeup to prevent spurious wake events
After=multi-user.target

[Service]
Type=oneshot
ExecStart=/bin/sh -c 'echo XHCI > /proc/acpi/wakeup; echo TXHC > /proc/acpi/wakeup'

[Install]
WantedBy=multi-user.target

sudo systemctl enable disable-usb-wakeup.service
sudo systemctl start disable-usb-wakeup.service

Ubuntu 24.04
nvidia-driver-590-open 590.48.01
NVIDIA GeForce RTX 3080

$ echo $XDG_SESSION_TYPE
x11

(not running Wayland)

The first line below (from journalctl -b -1) was key for me:

kernel: NVRM: GPU 0000:01:00.0: PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please  refer to the 'Configuring Power Management Support' section in the driver README.
kernel: nvidia 0000:01:00.0: PM: pci_pm_suspend(): nv_pmops_suspend+0x0/0x50 [nvidia] returns -5
kernel: nvidia 0000:01:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1b0 returns -5
kernel: nvidia 0000:01:00.0: PM: failed to suspend async: error -5
kernel: PM: Some devices failed to suspend, or early wake event detected

Following that clue (and working my way through all the ideas described in this thread), I edited /etc/modprobe.d/nvidia-graphics-drivers-kms.conf to

# This file was generated by nvidia-driver-590
# Set value to 0 to disable modesetting
options nvidia_drm modeset=1

# Preserve video memory on suspend/resume
options nvidia NVreg_PreserveVideoMemoryAllocations=0  # <-- this is all I changed
options nvidia NVreg_TemporaryFilePath=/var

and ran sudo update-initramfs -u and rebooted.

... I also enabled a bunch of services, but I'm not sure it was necessary (and definitely wasn't sufficient):

$ systemctl list-unit-files | grep nvidia
nvidia-hibernate.service                     enabled         enabled
nvidia-persistenced.service                  static          -
nvidia-resume.service                        enabled         enabled
nvidia-suspend-then-hibernate.service        enabled         enabled
nvidia-suspend.service                       enabled         enabled

On Debian 13 (Trixie) I have fiddled with nvidia CUDA toolkit installed from https://developer.nvidia.com/cuda-downloads, then uninstalled it and opted for the Debian native packages (nvidia-cuda-toolkit).

As reported by others here, after the reboot suspend is broken, and there are broken symlinks:

find /etc/systemd -type l -exec file {} \; | grep broken | grep nvidia
/etc/systemd/system/systemd-suspend.service.wants/nvidia-suspend.service: broken symbolic link to /usr/lib/systemd/system/nvidia-suspend.service
/etc/systemd/system/systemd-suspend.service.wants/nvidia-resume.service: broken symbolic link to /usr/lib/systemd/system/nvidia-resume.service
/etc/systemd/system/systemd-hibernate.service.wants/nvidia-resume.service: broken symbolic link to /usr/lib/systemd/system/nvidia-resume.service
/etc/systemd/system/systemd-hibernate.service.wants/nvidia-hibernate.service: broken symbolic link to /usr/lib/systemd/system/nvidia-hibernate.service

ls -l /etc/systemd/system/systemd-suspend.service.wants/nvidia-resume.service
lrwxrwxrwx 1 root root 45 12 set 07.16 /etc/systemd/system/systemd-suspend.service.wants/nvidia-resume.service -> /usr/lib/systemd/system/nvidia-resume.service

In my case though, I fixed not by removing the symlinks, but by restoring the targets:

sudo apt remove nvidia-suspend-common
sudo apt install nvidia-suspend-common
ls -l /usr/lib/systemd/system/nvidia*
-rw-r--r-- 1 root root  270  8 apr  2025 /usr/lib/systemd/system/nvidia-hibernate.service
-rw-r--r-- 1 root root 1501 17 dic 02.37 /usr/lib/systemd/system/nvidia-persistenced.service
-rw-r--r-- 1 root root  321  8 apr  2025 /usr/lib/systemd/system/nvidia-resume.service
-rw-r--r-- 1 root root  258  8 apr  2025 /usr/lib/systemd/system/nvidia-suspend.service

Now the symlinks are not broken anymore and suspend/resume works again! Hope this helps
