Raspberry Pi 4 - Ubuntu "Night Light" Not Working

[/RaspberryPi]

Hi all,

Got my first Pi last week, and it's pretty fun so far. My favorite OS so far is Ubuntu. I installed it on the SD card via the "Raspberry Pi Imager" app under the "Other general-purpose OS" option on my Windows PC. Ubuntu seems to be working decently, but the "Night Light" fuction in the "Displays" menu does not work. I like using it to reduce blue light and strain on my eyes. I've tried multiple ways of trying to fix this, including reinstalling the OS.

Does anyone have any suggestions? It's been a pain to keep turning on and off my monitor's blue light setting.
