+Subject: [PATCH] udev: Allow wayland on hybrid vendor nvidia machines
+
+We currently disable wayland on machines with the vendor
+nvidia driver upstream if hybrid graphics are in place because there
+is poor performance for multimonitor use cases.
+
+But springing that change on users in F37 this late in the game
+isn't nice, so instead default to Xorg and provide wayland as an
+option in the menu.
