Fedora 43 suspend mode does not work

[kozobp]

Hello,
many thanks for your great description; it works fine for me with Fedora 43 Workstation (HP Laptop + NVidia Quadro)
However, I discovered an issue: my laptop did not recover from suspend mode - no screen at all.
I tried to do the steps below which were necessary with Debian/Ubuntu, and it works for me.
It would be great if you could extend your guide with this aspect as well. Many thanks! :)

Enable NVIDIA Power Management Services

Ensure the necessary systemd services are enabled to handle power states. Run these commands:

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

Enable Video Memory Preservation

Create or edit /etc/modprobe.d/nvidia-power-management.conf to add the following line to ensure memory is preserved during sleep:
options nvidia NVreg_PreserveVideoMemoryAllocations=1
Note: After this, reboot or run sudo dracut -f to apply changes.

I am not a pro, so I do try-and-error based on some research like this Google search
