Recently I realized that whenever I wanted to change to any of the console windows (Ctrl+Alt+F2 - Ctrl+Alt+F6), my screen simply blanks out and goes into standby due to lack of input from my graphics adapter. This issue was definitely not there on Fedora 31, but I cannot say whether it was in Fedora 32 from the start or started somewhat later. The system is a fresh installation and not an upgrade.
While I can regain control of the computer by pressing Ctrl+Alt+F1 (GDM greeter screen) or Ctrl+Alt+F7 (graphical environment after being logged in), the change to the plain text console window no longer works.
Running journalctl -f
with elevated permissions I get the following output (I timed the switch to make it easier to spot in the logs, which is why the timestamps are all with zero-seconds):

The last two lines are the result of me pressing Enter after a short time in the feeble (and futile) attempt to revive the screen.
Suspecting graphics driver issues, I may need to mention that I have a GeForce GTX 1080 using the following drivers:
$ sudo dnf list installed "*nvidia*"

The kmod packages are not manually installed by me, but must have been installed through the akmod package when installing a new kernel.
GRUB starts my installation using the following line:
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 rd.lvm.lv=Samsung_SSD_970_PRO/system rhgb quiet intel_iommu=on"
Does anyone have a solution and/or can hint me to the appropriate file to verify its contents? If more logs or information is required, I am happy to supply it.
