BTW: I also update the driver to version 520, and upgrade ubuntu to 22.04.1 LTS. Works fine.
sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.service
worked for me. Thank you very much.
For me, with nvidia-driver-495, the simple solution was to remove the damaged symlinks from systemd. You most likely have them if you upgraded from nvidia-driver-470, because 470 still included the .service files in /lib/systemd/system/. The files are no longer included in 495 but the postinst script does not remove the symlinks. So, remove them with:
sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.serviceWorks instantly, no need of rebooting or logging off.
This does the job. Thank you.
sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.service
Thank you, This worked in my case.
The method works. In case you need fresh files install the services, you can get your driver version from NVIDIA. Use nvidia-smi to get the exact version and then run the .run file with --extract-only flag: sudo bash NVIDIA-Linux-x86_64-515.65.01.run --extract-only.
Then you run the given commands setting the TMPL_PATH to the path where you've extracted the files. Keep in mind that the files for this driver (515.65.01) have a slightly different locations as stated in the original post. So the updated commands should be like this:
TMPL_PATH=/home/user/Downloads/NVIDIA-Linux-x86_64-515.65.01/systemd
sudo install --mode 644 "${TMPL_PATH}/system/nvidia-suspend.service" /etc/systemd/system
sudo install --mode 644 "${TMPL_PATH}/system/nvidia-hibernate.service" /etc/systemd/system
sudo install --mode 644 "${TMPL_PATH}/system/nvidia-resume.service" /etc/systemd/system
sudo install "${TMPL_PATH}/system-sleep/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. The power drain I see before is not related to nvidia graphic card.
I tried to put the alienware laptop to airplane mode and pull out usb dondle before put into suspend, and put in the backpack for the whole night. The battery level only down by 9% which is normal, and no extra heat in the backpack.
