Error launching under the latest version of Sway: dropped KDE idle protocol in favor of standard idle-notify

[jmarca]

I recently upgraded sway to use the git version, not the release version (from last February).

activitywatch runs fine, but this wayland window watcher does not.

I get the following error:

aw-watcher-window-wayland
### Setting up display
### Fetching wayland globals
### Setting up toplevel manager
### Setting up idle timeout
thread 'main' panicked at 'Wayland session does not expose a Idle object, this window manager is most likely not supported: Missing', src/idle.rs:79:10
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

After poking at this and looking at the commit logs of Sway, perhaps this commit in the sway project is the culprit?

    Drop support for KDE's idle protocol

    We support the standard idle-notify protocol since Sway 1.8.

If this is unrelated, I'd be grateful for pointers to how to fix this.

Thanks for reporting!

Looks like we need to implement idle-notify support @johan-bjareholt

If you don't want to wait: awatcher supports both Kwin Idle and idle-notify: https://github.com/2e3s/awatcher
