While working on the Fedora MiracleWM transition to Dank Material Shell, I discovered that Anaconda will crash if the org.freedesktop.ScreenSaver inhibit API is not available. This is not guaranteed to be available on Wayland, as the replacement API is the wayland protocol idle-inhibit-unstable-v1: https://wayland.app/protocols/idle-inhibit-unstable-v1 On Wayland, it should attempt to grab an inhibitor using the Wayland protocol (but not crash if it can't, because no inhibit support means no screens turning off anyway). Reproducible: Always Steps to Reproduce: 1. Download Fedora MiracleWM 44 20260216.0 ISO 2. Boot and open foot 3. Run liveinst Actual Results: Crashes on fdo screensaver API Expected Results: Does not crash and launches Anaconda properly
Created attachment 2129747 [details] Screenshot showing the crash Attached is a screenshot showing the crash on a Rawhide image (it also occurs on F44).
Proposed as a Freeze Exception for 44-beta by Fedora user ngompa using the blocker tracking app because: Anaconda crashing if there's no legacy org.fdo.ScreenSaver interface is not great for Wayland spins that don't have this.
