Public bug reported: When the computer is sitting at the login screen with noone logged in, scripts that run 'w' to find out how many human users are logged in get a report of '1' instead of '0' like they should.
An example of a script that does this is the checklogi.sh script here: http://www.mythtv.org/wiki/Using_ACPI_%26_MythTV_to_run_other_applications The checklogin.sh script is used to prevent MythTV from shutting down the system when it is idle if a human user is still logged into the computer. The fact that the GDM login screen pretends to be a user prevents shutting the system down when MythTV is idle and noone is logged in. I have hacked the script on my machine to make this work, but it is not generalized and I can think of several cases where it will fail on a different setup. The script was working on lightdm, but I had to switch to GDM due to a bug in lightdm that sometimes breaks xwindows.
