Idle detection broken on GNOME

[salim-b]

In the revamped Furtherance based on Iced (v24.10.2), the idle detection is broken on GNOME. I tested with Bluefin (bluefin-dx:gts which is currently on GNOME 45.6) and Ubuntu 22.04 (GNOME 42.9), using the Flatpak.

When Furtherance is in the foreground while the idle time is exceeded, it crashes:

When Furtherance is not in the foreground, it doesn't crash. But the timer is not paused when the idle time is reached.

Thanks for reporting all of these bugs! This is a big one. I'll get to work on it right away.

I've tracked this down to an issue with the D-Bus connection when Furtherance is installed via Flatpak. For now, you can fix this by installing Flatseal and changing Furtherance's permissions to allow D-Bus session bus.

I'm working on a permanent fix now.

[rickykresslein]

The bug was due to a missing permission in the Flatpak manifest (--talk-name=org.freedesktop.Notifications), and it crashed the app due to the unsafe unwrap of the Notification. Both of these issues are now fixed. I will release a Flatpak update soon.

Thank you for the quick response and fix! I can confirm that allowing to talk to org.freedesktop.Notifications makes the Flatpak work as supposed:

flatpak override --user --talk-name=org.freedesktop.Notifications io.unobserved.furtherance

When Furtherance is not in the foreground, it doesn't crash. But the timer is not paused when the idle time is reached.

This is still an issue in v24.10.3, thus I openend #155.
