[all variants] power management without login

http://ubuntuforums.org – Hi, I have been trying to understand this with google for a day now, it's time to ask. I don't fully understand how the power management works in ubuntu desktop and it's derivatives. My question is which services influence the computer when no user is logged in but the X environment is loaded? Is the loading of the X server a trigger for the power management or is it session dependent? I have considered the acpid and apmd but those only emit events and accept instructions. My computer goes to sleep automatically, and the idle timers are supposed to be controlled by gnome-power-manager or (Hardware)

Hello,I have gnome3 and gnome-power-manager installed to two different systems. In both cases I can not get the power manager to suspend the computers. Maybe I don't understand what power manager is supposed to do? My interpretation is that if I check the box that says put computer to sleep after xx minutes that it will automatically suspend after xx time period of inactivity.

Power Management settings 3 years 44 weeks ago

What are the default settings for power management? I've messed with it a little and I noticed my screen doesnt lock when I leave my computer inactive for a certain period of time. Also the 2 options in the Power Management."

Hi Folks.

I have an odd problem since preupgrading from Fedora 12 to Fedora 14 (which otherwise worked quite well, FWIW).

I don't know if this is a bug or not so I am not sure how to proceed. :confused:

I run Fedora Linux 3.6.7-5.fc18.i686 with the KDE desktop v 4.9.3.

In 'System Settings' - 'Power Management' - 'AC Power', 'Button events handling'; I have it set to 'sleep' when the laptop lid is closed and it does this OK.

Hi there,

I am running Ubuntu 9.04 on a Toshiba laptop and having trouble getting it to suspend when idle.

In system -> preferences -> power management, under the 'battery power' tab I have set it to 'put computer to sleep when inactive for 11 minutes'.

I'm trying to figure this out, and not having any luck.

Under System | Preferences | Power Management

The Power Management Preferences dialog has a tab for 'On AC Power' and 'On Battery Power'.

Each of those tabs has a checkbox marked 'Dim Display when Idle'.

I have read (I think) all of the relevant wiki pages. (But I could be wrong - they seem to criss-cross in various ways and I go in circles!) I've also googled what I can, read the man pages and been through all the config files I could find.What I planned to do: do power management with acpid and laptop-mode-tools with pm-utils, which I believed complemented the others.

Power & Sleep Management 28 weeks 3 days ago

I'm running 12.10 with xmonad.

Trying to ensure that the right things happen when I close laptop lid, etc. I see Internet search results for similar issues that mostly point towards gnome-power-manager.

On Sunday we reported that ATI in-kernel power management was moving along after AMD's Alex Deucher spent some time in recent days building upon Rafał Miłecki's initial power management support. Alex's patches added GUI idle IRQ support, support for changing the GPU clocks when the engine is idle...
