Public bug reported:
After upgrading 24.04 to 24.10, external HDMI did not work anymore on Predator
Helios Neo 16 laptop (no signal at all).
Found in settings that display driver has been switched to "X.Org X Server -
Nouveau display driver" automatically during upgrade. Reverted back to "NVIDIA
driver metapackage nvidia-driver-560 (propietary)" and external HDMI came back
to live. IIRC 24.04 also used the propietary one by default
--> look like the new driver does not support nvidia graphics cards
fully on predator laptop series.
