Allow gamma custom ranges in the Ubuntu driver to allow for night time color changes software to work (f.lux, Redshift, etc...)
Gamma color calibration seems to be unavailable for the Displaylink on Ubuntu.
Allowing it will enable night time screen color changing software to work and also allow manual customization with xrandr commands.

What a bad idea was to invest time and money to DisplayLink products. After I spent 20 hours to make this crap work on linux with my hybrid nvidia+intel laptop, I still have to burn out my eyes at nights. Total waste. This shit product will go to anvil soon when i have appropriate hammer.

I am using Lenovo Hybrid Docking Station (USB-C/USB-A) and Ubuntu 20.04. Since DisplayLink can't render colors for external monitors, night light is not working. Moreover, the main display ( Laptop ) is also malfunctioning when night light is enabled. It would be great if night light can be enabled in Ubuntu OS.

Yes! Would love this as I use my Ubuntu PC nearly only in the evening or night where the ability to control brightness and color temperature becomes very important.
