In continuation to my original post.
I’ve updated Garuda again last week. The problem returned, this time with the LTS kernel. So now I had the problem in all kernels.
I found a working solution and wanted to share it with you here.
I turns out that the ‘nvidia’ driver does not save the nvram parmeters before suspension/hibernation. This causes the error mentioned in the previous post. To fix this you need to do the following, I found that all these services existed on my machine but were not activated:
sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-hibernate.service
sudo systemctl enable nvidia-resume.service
sudo nano systemd.conf
Add following line at the end of the file:
options nvidia NVreg_PreserveVideoMemoryAllocations=1
After these steps I rebooted. Since then, for the last few days, the problem has gone away.
Hope it helps.
