v2.0.1

Highlights

• Fixed: daemon not switched over when upgrading from cosmic-flux via sudo. The post-install script could neither stop the old cosmic-flux-daemon nor enable the new unit from a sudo context (no access to the user session bus), leaving the old daemon running from a deleted binary until the next login. The service is now enabled system-wide via systemctl --global enable, with a best-effort immediate stop/start for the installing user.
• If you already upgraded to v2.0.0 and hit this, either log out and back in, or run:

  systemctl --user stop cosmic-flux-daemon
  systemctl --user enable --now cosmic-ext-flux-daemon

• Reminder from v2.0.0: re-add the Flux applet to your panel once (the App ID changed) via Settings > Desktop > Panel > Applets. See the v2.0.0 notes for everything in the rename release.

Install

sudo apt-get install -y gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-vaapi
sudo dpkg -i cosmic-ext-flux_<version>_amd64.deb

Add the Flux applet to your panel via Settings > Desktop > Panel > Applets.

Uninstall

systemctl --user disable --now cosmic-ext-flux-daemon
sudo dpkg -r cosmic-ext-flux

Requirements

• COSMIC desktop environment
• GStreamer 1.x with video decode plugins
• VA-API drivers recommended for hardware decode

What's Changed

• Fix postinst systemd handoff under sudo by @franz-net in #10

v2.0.0

Highlights

• Project renamed to comply with the COSMIC trademark policy (#5):
  • Package: cosmic-flux → cosmic-ext-flux
  • Binaries: cosmic-ext-flux-daemon, cosmic-ext-applet-flux
  • App ID / D-Bus: com.system76.* → io.github.franz_net.*
  • Display name: Flux — live video wallpapers for the COSMIC™ desktop
• Installing this package automatically removes the old cosmic-flux package and its systemd service
• Existing settings are migrated automatically on first start — no reconfiguration needed
• Auto FPS (#4): new "Auto FPS (match source)" toggle plays the video at its native framerate — now the default for new installs; the manual slider remains as a power-saving cap and now adjusts in steps of 1 (so 24 fps is selectable)
• Fixed: wallpaper not restoring after login (#2): pressing Play after a Stop now re-enables autostart, so the wallpaper comes back at the next login
• French translation for the applet (thanks @ligenix!)

Install

sudo apt-get install -y gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-vaapi
sudo dpkg -i cosmic-ext-flux_<version>_amd64.deb

Add the Flux applet to your panel via Settings > Desktop > Panel > Applets.

Uninstall

• Fix autostart after login (#2) and add auto FPS mode (#4) by @franz-net in #9

New Contributors

• @franz-net made their first contribution in #7

Upgrading from cosmic-flux? Two manual steps

1. Re-add the applet to your panel (one-time): the App ID changed, so remove the old entry and add Flux via Settings > Desktop > Panel > Applets.
2. If your wallpaper doesn't come back after the install, the systemd handoff may not have run (fixed in the next release). Run:

   systemctl --user stop cosmic-flux-daemon
   systemctl --user enable --now cosmic-ext-flux-daemon

Your settings and wallpaper are migrated automatically — if the wallpaper doesn't resume at next login, just press Play once in the applet (this also fixes configs affected by #2).
