Fedora-33: root# exec systemctl suspend (no longer works)

Hello Friends:

As of yesterday, after performing a “sudo dnf -y update” on my Fedora-33 machines, I’ve been having all kinds of suspend and resume problems, which vary depending on the laptop model and therefore on the nVidia card.

Let’s start with just on laptop. On a ASUS g750 laptop, with the below card, suspending the O/S no longer works (but did for many years):

user$ sudo lspci | grep -i nvidia # Show card information.
01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 780M] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller (rev a1)

Now, when I issue, “root# exec systemctl suspend” (which worked for years), the O/S starts to suspend, with the screen even going off momentarily, but then comes right back.

I put more information about this problem here:

Any ideas? Thank you in advance.
