In the logout dialog of xfce4-session, you can check the option "Save session for future logins". I think it would be better if that option would disappear from the logout dialog. Because it often causes some confusion and (minor) problems for inexperienced Xfce users. It's not an important usability bug, but still a "paper cut". Inexperienced users often check that option (or leave it checked, because some distro's ship Xfce with this option enabled by default), without knowing what it means and what it's good for. And then they ask for help on the forums, because every time they log in, all kinds of applications are being launched automatically.... So I think it would be a good idea to remove this option from the logout dialog (and make it disabled by default, if that's not the case yet). In my experience, saving a session is rarely ever useful at all. And you can still enable saving a session by the settings manager.
My experience is also that the setting does indeed confuse many new users. "Save session" means nothing at all to most of them. I also think the option should be disabled by default and that the label should be reworded to something less technical. It should be made clear what this does in practice. I'm not sure about removing the option from the dialog, unless it can be restored with a setting. It's been there for years and there are surely many users who have grown to rely on it.
Saving session is useful for example if you can't hibernate. I would not strip Xfce of features just because some people don't use them.
@Jarno Suni: I am not asking to strip this feature from Xfce. I am only requesting to remove it *from the logout dialog*. :-)
And all I'm saying is that the option could do with a more newbie-friendly label. It should not be enabled by default regardless. I do agree that sessions are a useful feature, and this option should not be hidden away.
When you see the setting in the dialog, you don't have to remember what you have set elsewhere.
