Bug#726336: [gnome-power-manager] Gnome thinks I am on Battery when I am on AC

[Gennady Uraltsev]

I found some sort of clue. Updating the system through aptitude I once
got this error:

setterm: cannot (un)set powersave mode: Inappropriate ioctl for device

I do not know what package was concerned (updated quite a few). Maybe it
is not a problem of gnome after all. I tried searching google but people
complained about this error on servers and they wanted to disable power
management completely. This is not my case, however so just adding
acpi=off to the boot command will not do. In any case shouldn't gnome
power manager at least say something in .xsessionerrors if it encounters
a problem setting powermanagement settings?
