I have a 2019 Dell XPS 13 2-in-1 7390 connected to Dell D6000 docking station and using Dell SE2719HR secondary monitor. The dock uses DisplayLink technology, for all it matters. My Ubuntu version is 20.04.
When I enable Night Light, it is only displayed on the laptop’s built-in monitor. Even when I close the lid (which turns off the built-in monitor), Night Light still isn’t displayed in the external monitor.
I’ve tried mirroring displays, extending displays, setting external display as only one active, nothing helped. I went through this topic here and all suggested solutions, none helped either.
Is this a bug of some sort, or am I doing something wrong?
