after some distro hopping i landed at Manjaro Budgie, and i guess i’ll stay with it.
I’ve experienced always the same issue with Night Shift:
On multi monitor setup always one screen doesn’t switch to Night Shift mode.
There are ways to workaround this issue on other distros, but with Manjaro i haven’t found a solution.
This is a known issue, partially fixed with Gnome 3.28, but due to further needed upstream development with Night Shift i request a switch to Redshift app.
It works out of the box with Manjaro (Budgie) on all screens and the Redshift geoclue2 issue is already fixed (on Manjaro).
