# Use systemd for managing NVIDIA driver suspend in drivers ====>>> PRIOR to version 470 <<<=====

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

For me on driver 535.216.03 and GeForce RTX 2070 Mobile / Max-Q the following services where located under /usr/lib/systemd/system/:

• nvidia-hibernate.service
• nvidia-persistenced.service
• nvidia-resume.service
• nvidia-suspend.service

This meant taht I only had to enable them with

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

This is my current setting and it's working for me (Linux Mint 22, Nvidia GeForce GTX 745 using Nvidia 550.107.02 driver)

sudo nano /etc/modprobe.d/nvidia-graphics-drivers-kms.conf

and add these lines into it:

options nvidia-drm fbdev=1 options nvidia NVreg_PreserveVideoMemoryAllocations=1 options nvidia NVreg_TemporaryFilePath=/var/tmp

This fixed my issues!

(Issue remaining: "unable to change power state from D3hot to D0")

I also tried the answer from dmikushin, but it didn't change anything!

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
