SUMMARY I initially filed https://github.com/bilelmoussaoui/ashpd/issues/260, but the developer suggested that the issue is likely on KDE's side. STEPS TO REPRODUCE 1. Install and launch https://flathub.org/apps/com.belmoussaoui.ashpd.demo 2. On the "Inhibit" page, select "Suspend" and click "Start session" OBSERVED RESULT An error is logged by the demo, see https://github.com/bilelmoussaoui/ashpd/issues/260. According to ashpd's developer, "the error means that the portal returned a tuple of (2, {}) as a response. Which usually means a portal impl error". EXPECTED RESULT Inhibition starts, and the "End session" button is enabled, like in GNOME 47.
