Is my Macbook 5,2 (year 2009) (graphics Nvidia; nvac/nv96) incompatible with the "night light" function in 23.04?
I don't think any proprietary drivers are available for the Nvidia card.
I'm new to Linux and Ubuntu, so I don't know how to answer the question, "Are you using GNOME?". I installed Ubuntu from the Live USB and have not done anything that I'm aware of related to GNOME. In Setting>About, my GNOME version is listed as "Not Available".
Should give you an output of your desktop environment.
