https://wiki.archlinux.org/title/NVIDIA/Tips_and_tricks#Preserve_video_memory_after_suspend
```
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.
```
```
sudo cat /etc/modprobe.d/nvidia.conf
options nvidia_drm modeset=1
options nvidia NVreg_PreserveVideoMemoryAllocations=1
options nvidia NVreg_RegistryDwords="OverrideMaxPerf=0x1"
```
