Description Cameron Gutman 2021-01-21 03:34:45 UTC 
SDL doesn't currently support inhibiting the screensaver on Wayland. This causes the display to go to sleep while playing games with a gamepad on the Wayland backend.

To suspend the screensaver, we'll support both the org.freedesktop.ScreenSaver D-Bus API (like the X11 backend does) and the idle_inhibit_unstable_v1 Wayland protocol for compatibility with most Wayland compositors.

Patch

Tested org.freedesktop.ScreenSaver on GNOME 3.38.3 (which doesn't support idle_inhibit_unstable_v1).

Tested idle_inhibit_unstable_v1 and org.freedesktop.ScreenSaver on KDE Plasma 5.20.8.
Comment 2 Cameron Gutman 2021-01-21 03:39:11 UTC 
FYI: The SDL_DBus_Quit() code (and accompanying FIXME) was copied from the X11 backend.
