[Bug 962086] [NEW] power button not working when not logged in or on tty

[Roger John]

Public bug reported:

Hello,
i use my machine as a print server and discovered the following since 11.10: If i am not logged in (e.g. started the machine just for printing from a network client), the power button won't shut down the system when pressed. I have to log into gnome or issue poweroff via tty/ssh. I know this worked in previous versions of ubuntu, and maybe i found a clue.
In /etc/acpi/powerbtn.sh the gui power managers are searched. In previous versions of ubuntu, the script looked for gnome-power-manager, but now it's looking for gnome-settings-daemon, which seems to be running any time lightdm is running.
I could work-around this by replacing gnome-settings-daemon in /etc/acpi/powerbtn.sh with gnome-session. This does not work when working on tty with a running gnome-session in bg, the session is ignoring the keypress (i heard this was different in older versions where it wasn't checking if on active console).

Greetings
Roger John

PS: I reckon that pressing the power button while on tty with a running
X session, the system should not shut down at once. But it could kill
the tty and switch to the x session, for example, or do something
informative.
