Feature changed by: Bruno Friedmann (bruno_friedmann) Feature #313842, revision 5 Title: auto sleep on login screen with kdm openSUSE Distribution: Unconfirmed Priority Requester: Desirable Requested by: Philippe Baril Lecavalier (p_barill) Partner organization: openSUSE.org Description: Any multi-user machine is prone to spend a fair amount of time on the login screen. How come there are no power management settings for this situation? If a user leaves a computer unattended for a few minutes while logged in, it will go to sleep after some minutes. Not so if it stays on the login screen. In this case and with kdm, the user must manually "suspend to RAM", and know the difference between this and "suspend to disk". Besides, I observed that the procedure to initiate sleep on the kdm login screen is quite involved for someone with a low computer literacy: Click on menu > shutdown > hold suspend > select "suspend to RAM" Clicking on "suspend" defaults to hibernate (I think the default should be sleep, not hibernate). Personally, I don't mind. But it's involved enough that some people told me "I got to write that down". There are some ways to automatically logout users after some period of inactivity. This can be justified to avoid waste of network resources. Similarly, the idea of enabling "sleep after x minutes" on the login screen is to save power and avoid unnecessary wear of equipment. I do not dare annoy you with yet another default setting request, but a simple way to turn this on. This could be useful in a variety of environments, such as home computers and computer labs with low usage rates (and reduce cooling bills too!). Obviously I deduce little need for this on a single-user machine. The only time I see the login screen is when I boot. Thus my logoff=shutdown. I request this for kdm.
