NVIDIA Suspend fix

TMP_PATH=/var/tmp
TMPL_PATH=/usr/share/doc/nvidia-driver-460/

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

It works for me. I got Ubuntu 24.04 and nvidia driver Version: 575.57.08.

The original status was:

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

I ran the following command:

$ sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-hibernate.service
sudo systemctl enable nvidia-resume.service
Created symlink /etc/systemd/system/systemd-suspend.service.wants/nvidia-suspend.service → /usr/lib/systemd/system/nvidia-suspend.service.

Created symlink /etc/systemd/system/systemd-suspend-then-hibernate.service.wants/nvidia-resume.service → /usr/lib/systemd/system/nvidia-resume.service.

And then the problem is fixed. It does not wake up immediately after suspending any more:

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

sudo systemctl unmask nvidia-suspend
sudo systemctl enable nvidia-suspend
sudo systemctl unmask nvidia-resume
sudo systemctl enable nvidia-resume
sudo systemctl unmask nvidia-hibernate
sudo systemctl enable nvidia-hibernate

This fixed my issues! Ubuntu 24.04.3 LTS, Driver Version: 580.82.07, CUDA Version: 12.8

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
