Sadly not available for Wayland because of Wayland's architecture. KDE and GNOME have some functionality built in but I don't know how good it actually is compared to redshift.

That's not quite true: the compositor needs to support it. There's a protocol [1] for it that's supported by a redshift with a patch [2]. It also works out the box for any wlroots-based [3] compositors, like sway [4].

Footnote: Stable sway (0.15) is not based on wlroots, the next version (1.0) will be.

Footnote footnote: stable sway (0.15) supports redshift as well, albiet with an older version of the protocol.

Footnote footnote footnote: Thanks for your work on sway. I still haven't switched to Wayland full-time, but sway was definitely a huge push for me to try it out. :D

Thanks for the kind words :)

I've recently upgraded from Ubuntu 16.04.5 to 18.04.1. The built-in Night Light functionality is actually OK. A little bit too red for my taste, but it does what it should.

I have a monitor connected to Xubuntu with X.org using redshift side by side with one hooked up to Fedora and GNOME. I think the latter often looks a little redder around sun set, but maybe my times aren't synced. Both look great.

I have to relaunch redshift when I reboot. The GNOME setting just had to be set once.

You'll probably find that times are synced fine due to NTP... It's more likely to be colour temps, or possibly redshift's "location" setting that are different.

This is one of those reasons why I hope Wayland doesn't take over too fast. I know it is awesome, and new, and has tons of benefits, but there are a few things that I couldn't live without that it doesn't have :(

I use the built-in Gnome night mode with Wayland on Fedora and it works well.

Occasionally it has failed for some reason, at night, and I'm shocked by the blue light flooding my senses.
