I am getting a web server setup at home on an older AMD 2400+ desktop. I have Ubuntu 11.04 installed and running however, after a time, I can no longer browse to the server. When I go to the keyboard and press a key, everything magically works again.

I have looked through the BIOS and I am not seeing any power saving features enabled. Is there anything like that in Ubuntu? Can it be disabled?

I don't have any GUI installed. This is console only.

Have you looked at:

System -> Preferences -> Power Management

On AC Power Tab, Put computer to sleep when inactive for: "Never"


Can you open up "gconf-editor"?

Look in: /apps/gnome-power-manager/timeout

Try setting sleep_computer_ac to 0

I'm not positive if anything else needs to be changed as well.

How do I do that on the console? I don't have a gui installed. –  Mike Wills Jun 6 '11 at 20:17
@Mike Wills Updated since you have no gui –  Jason Iverson Jun 6 '11 at 20:41
Again, I don't have gnome or any of that installed. It is a pure console. –  Mike Wills Jun 7 '11 at 1:47
WTF is /apps??? –  mehaase Jun 28 '12 at 13:41

Please try looking into these links - cyberciti.biz and Arch forums

This is an excerpt from the cyberciti.biz link:

By default, the Linux kernel will use screen-save option to disable it you need to type this command (it turns off monitor VESA powersaving features):

$ setterm -powersave off -blank 0

If it dumps back you with an error that read as follows: cannot (un)set powersave mode

You need to shutdown X window system and rerun the above command. Better, add following two commands to your ~/.xinitrc file:

setterm -blank 0 -powersave off -powerdown 0
xset s off

The right answer for this located here:

Have you tried adding the kernel options acpi=off apm=off to the GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub?

Then run sudo update-grub and reboot your computer.

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  Eliah Kagan Feb 1 '13 at 13:26

I think you might want to turn both suspend and screen lock off. Here are a few screenshots that might help you navigate which settings I modified to make my ubuntu virtualbox never sleep.

The op specifically said "I don't have any GUI installed. This is console only." –  Dan Esparza Feb 18 at 16:34

Add the following line to the end of your kernel parms in /boot/grub/grub.conf:

I suppose this is for the console going blank, doubt it will stop sleeping –  Nanne Feb 1 '13 at 12:03
And considering that I already have a working answer, there really isn't a need for another answer. –  Mike Wills Feb 1 '13 at 14:47
