The shutdown-at-night package is currently unable to detect when some desktop environments are used, because they fail to update utmp when users log in. The package is intended for environments like offices or schools that want to save power by turning off unused machines at night and turning them back on in the morning. When it is unable to discover that a machine is in use, it will turn off the machine while people are working on it. I've gotten reports that teachers experience their machine turn off while they are writing at 16:00. The following change solve the issue by detecting the X login screen for KDE, Gnome and XFCE environments, and assuming the machine is unused if the login screen can be seen. The same change was already uploaded to unstable as version 0.13, with a few other unrelated changes.
