Subject: [gnome-power-manager] Gnome thinks I am on Battery when I am on AC

[Message part 1 (text/plain, inline)]

Package: gnome-power-manager
Version: 3.8.2-1
Severity: important

Dear developers,

Starting from some time ago I noticed that my Gnome 3 thinks that I am
on battery even when I am on AC. In particular it brightens down my
screen and sleeps the laptop (Thinkpad W520) after some time of
inactivity even though these settings are enabled (through dconf) only
for battery powered operation. This worked some time ago (several weeks)
and got broke at some point (I cannot pin down when since it took some
time to notice). 

Thanks!

Gennady

What does `acpi' say when gnome thinks you're on battery while you're not?

This is the output of

I have tried studying the phenomenon a bit more. Maybe the problem is
actually that gnome-power-manager doesn't respect the settings in
dconf. 

My current settings are given by:

$ dconf dump /org/gnome/settings-daemon/plugins/power/
[/]
button-power='interactive'
critical-battery-action='shutdown'
idle-dim-time=60
sleep-inactive-ac-type='blank'
sleep-inactive-battery-timeout=300
lid-close-ac-action='blank'
idle-dim-ac=false
idle-dim-battery=true
idle-brightness=30
sleep-display-battery=180
lid-close-battery-action='suspend'
sleep-inactive-ac-timeout=600
use-time-for-policy=true

Even though it is told not to dim on ac "idle-dim-ac=false" it does so
and even tough sleep-inactive-ac-type='blank' it suspends when the
battery timeout is reached. I will try to experiment more. I am now
trying to reset and then configure all the values using dconf command
line tool and not dconf-editor. Lets see how it goes. 

Thanks!

Gennady.

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?
