A Linux alternative to Auto Dark Mode. Independent open-source project, not affiliated with or endorsed by Windows Auto Dark Mode.
FEATURES • Schedule & Instant Switch: Real NOAA astronomical sunrise, solar noon, sunset and solar elevation calculator from Latitude/Longitude, custom fixed-hour schedule, automatic periodic scheduler, and instant Light/Dark switching via vendored gsettings (org.gnome.desktop.interface color-scheme, gtk-theme, picture-uri / picture-uri-dark). • Theme & Wallpaper Mapping: Scans host GTK and desktop themes under /usr/share/themes, maps Light and Dark wallpaper images with live preview, and supports X11 root backdrop wallpaper painting (_XROOTPMAP_ID / ESETROOT_PMAP_ID) for window managers without GNOME Shell. • Smart Rules & Activity Log: Pauses automatic switches when a fullscreen window or specified WM_CLASS application (e.g. media player or editor) is focused via X11/EWMH, and keeps persistent JSON rules and timestamped switch history.
NOTES
• Connect the optional system-backup interface (sudo snap connect day-night-theme-switcher:system-backup) to scan host themes in /usr/share/themes and host GSettings schemas from strict confinement.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Day Night Theme Switcher, simply use the following command:
sudo snap install day-night-theme-switcher
Browse and find snaps from the convenience of your desktop using the snap store snap.
