To save and restore all video memory contents, use the NVreg_PreserveVideoMemoryAllocations=1 kernel module parameter for the nvidia kernel module and enable nvidia-suspend.service, nvidia-hibernate.service, and nvidia-resume.service.
See NVIDIA’s documentation for more details.
Thanks for the reply!
I’m not clear on how to set the Nvidia kernel module parameters per the above (exactly what command(s) to use)?
