Comment 3 for bug 837002

Hmhm, I tried to look at the code but it's a bit hard to exactly know where session is set.

But right now I didn't find any “default_session” (or similar stuff). display->priv->session is set when seat is initialized and then if session is selected in the drop down menu, but then there's no way to know if what we run is the default session or a selected one, and thus if we need to save it to dmrc or not.

In gdm (2.x), afair, when starting the session, is the one to be started is different from the saved one, it'll ask if the user wants to save it. But then I don't know how it handles the “default session”. It might just be that the fallback is done *later* and not earlier. But here, when starting the session, we don't have access to the seat so we can fallback on the seat session default.
