I dug into this a little and encountered a whole slew of issues, such that I'm really unsure how to file them or under what packages.
I'm using nvidia-driver-525 with one monitor plugged directly into the back of my computer and a second monitor plugged into a DisplayLink hub. The DisplayLink monitor works fine on the login screen and under Xorg but does not work under Wayland: when I log into Wayland the computer thinks that the DisplayLink monitor is active (i.e., the display settings applet claims that my display is extended to it and I can move my mouse off the edge of one screen and supposedly onto the other), but it's blank and the monitor claims it's not getting a signal. When I log into Wayland Nightlight is disabled and the settings applet for it says that it's unavailable. (And of course none of them are the same as the bug to which I'm adding this comment.) When I log into Xorg Nightlight is supposedly enabled but does not appear to do anything to the color of the display on either the direct monitor or the DisplayLink monitor, i.e., it doesn't appear to work. I'm guessing these are all separate bugs but I'm so overwhelmed by the number and variety of them that I'm not sure how best to report them. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1772212 Title: [nvidia] Night light doesn't cover all monitors fully Status in gnome-settings-daemon package in Ubuntu: Incomplete Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: Hi, The GNOME night light only seems to work on the first half of the first screen within a dual monitor setup (Ubuntu 18.04 stock, using X11 with Gefore GT240, NVIDIA proprietary drivers).
