Steps to Reproduce

Hi, Firstly just wanted to say - love the app.. Thank you so much for making it and maintaining it so well!

Expected Behavior

The AmbientLight effect should light up the keyboard according to the colors on screen

Actual Behavior

The AmbientLight lighting effect fails to activate when running the tool on Ubuntu 25.04, regardless of whether the session is Wayland or X11. Other effects appear to work as expected, but AmbientLight produces no visible output or change in lighting.

Command:

sudo ./legion-kb-rgb set -e AmbientLight

The command gives no errors/output on X11 but the keyboard does not light up at all
On Wayland:

The application panicked (crashed).
Message:  called Result::unwrap() on an Err value: Custom { kind: Other, error: "/usr/bin/dbus-launch terminated abnormally without any error message" }
Location: app/src/effects/ambient.rs:25

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.
