OS powers down without mouse or keyboard input and has to be rebooted

Bug Description

Binary package hint: gnome-power-manager


I only assume it has something to do with the power-manager,

but I really do not know.

When watching a movie or when not using input devices Karmic powers down.

First, the screen goes black, and most of the time it awakens

when keyboard or the mouse is pressed or moved.

Goes black again, every 10 minutes, for 3 or 4 times.

Then usually the 4th or 5th time of going black, video signal is lost,

sound stops, keyboard, mouse, suspend button are useless.

The PC has to be rebooted to function again.

Its like a silent crash, with no warnings, no crash report.

Power settings are on "Never" put computer to sleep, and

"Never" put display to sleep.

Screensaver is not activated, setting is on maximum 2 hour setting.

The PC and the Monitor should stay powered on indefinitely.

But Karmic not only powers it down regardless but fails to re-power.


This is without a doubt one of the most frustrating bugs in any

reputable OS.

I was about to recommend Karmic to some clients.

Unless this is fixed quickly, the value of UBUNTU will

drop below Windows XP.

Please do not let it come to this point.

Do not be Lucid before Karmic critical bugs are fixed!

Update on the power-management / ACPI problem:

CTR Monitor I use, is DELL 15 inch E771a.

ASUS P5E-VM HDMI mobo, Intel (82)G35 chipset,

integrated X3500 Graphics Media Accelerator,

Intel Core Duo CPU E4500 @ 2.2GHz,

2 GB DDR2 800MHz Memory,

Intel ALC883 HD audio. AMI 8MB BIOS -

Power management works great under Win XP & Vista.

Under Karmic, when I push the sleep button (suspend)

on my Logitech Media Keyboard, the OSD notifier tells me:

"Action disallowed" "Suspend support has been disabled".

This confirms my settings, that I do not want the PC

to go to sleep, nor the monitor to go to sleep.

Yet, Karmic still puts the Monitor, and then the PC to sleep,

within 10 minutes, with regularity. Eventually video signal

is cut, audio signal is gone, keyboard & mouse fail to

awaken the PC or the monitor, suspend button fails.

Evidently power-management or what ever program

regulates ACPI fails to respond to the settings,

& powers down.

I do not know how to get the attention

of the developers, to fix this Critical error!

I am still confident, that Karmic will be debugged,

Perhaps through Lucid updates.


Ubuntu forever!

As of now, this power-management

bug is fixed!

It does not occur in Lucid at all.

And keeping up with daily

updates for the Official Karmic

version has resolved most bugs.

Latest on gnome-power-manager:

I thought, that the bug was fixed,

but realized, that another power-

manager, guidance-power-manager

along with xscreensaver 5.10

were actually active.

I adjusted this power manager,

within xscreensaver settings to

1440 minutes each.

I deleted gnome power manager,

which is still as useless as it was

ever since Karmic.

I auto-start xscreensaver, and I can

now safely watch & download TV &

movies, without the PC causing a

video signal loss, due to gnome-


Since no one is really willing to

fix this horrific bug,

I recommend to just shelve

the gnome-power-manager,

and install KDE's


in consort with xscreensaver 5.10.

By the way, I am using Lucid Lynx

alpha which, in my opinion, works

better than Karmic.

Why even bother with Karmic if the

upgrade works even better? (mostly)


Ubuntu forever!

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of GNOME Power Manager is available on Maverick and we are wondering if this bug is still an issue for you with that version? Could you please test and comment back? Thanks in advance.

I am not sure this is a gnome-power-manager issue by itself. I experience this same issue using an ATI Radeon 8500 video card in Ubuntu 10.04. Unfortunately, I can test it in Ubuntu 10.10, maverick, because it shuts my video, keyboard, mouse off before I can get the grub menu. Changing to an Nvidia 6200 video card resolves the issue completely for me.

Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.
