A Quick Settings toggle for cardwire, the eBPF-based Linux GPU manager. Mirrors the UX of the Power Profiles Daemon tile: click to flip between Integrated and Hybrid, expand for the full mode list.
Tested against cardwire 0.5.0 on NixOS with GNOME 49 on an Asus G14 (2025).
The extension talks to the cardwired system daemon directly over D-Bus -
no pkexec, no shelling out to the CLI. cardwired's D-Bus policy is open
on the system bus, so calls go through silently.
Mode changes initiated from anywhere that uses cardwire set … from a terminal or other tool are detected via a dbus event watcher, no polling necessary.
Gnome Shell 45 or newer
cardwire must be installed and the daemon service must be running.
Download directly from the Gnome Extensions Page
You can manually install the extension from the zip file under the releases. The following commands will install it locally for your user
curl -L "https://github.com/chrispouliot/cardwire-toggle/releases/latest/download/cardwire-toggle@chrispouliot.github.io.shell-extension.zip" \
-o /tmp/cardwire-toggle.zip
gnome-extensions install --force /tmp/cardwire-toggle.zip
# log out, log back in, then:
gnome-extensions enable cardwire-toggle@chrispouliot.github.io
