How do I completely turn off screensaver and power-management?

Question

I looking for a method to turn-off the screensaver and powermanager but from the command line.

I'm aware this can be done via the GUI screen - but can this be done via the command line or via some configuration editor?

Answer 1

For 11.10

Disable the GNOME Settings Deamon's power plugin from the command line:

gsettings set org.gnome.settings-daemon.plugins.power active false

Alternatively, using dconf-editor from the dconf-tools package:

For the screensaver:

gsettings set org.gnome.desktop.screensaver idle-activation-enabled false

Or again via dconf-editor:

Answer 2

Make a plain text doc in your home folder and copy this into it.

#!/bin/bash
sleep 10 &&
xset s 0 0
xset s off
exit 0

Save the document as "screensaver_off.sh" (without quotes), then open a terminal and enter

chmod +x screensaver_off.sh

Then open up startup applications from the dash, click on the add button, name your start up application, and enter your command as:

/home/david/screensaver_off.sh

replacing "david" with your home folders name, then add a description and click add, reboot and your done, No more screen blanking.

You will have to do this per each user as default settings revert after logout or reboot.

You can go to System preferences. There is a program called "Brightnes and lock" (Im not shure how it is called in english. Look at my screenshot) In this menu you can define, when the screenlock is activatet.

Here is a solution that worked for me .. The problem I had was as I upgraded my Ubuntu 12.04 to 12.10 and to Gnome 3.6 the screen went black when idle for like 5 minutes even if I did not have any conventional settings for an active screen saver, needless to say it was sickeningly annoying ..

Here is the solution I used and it worked (and I have tried a lot of different things, spending too much time searching on startpage.com (google)

Scroll down to 'No screensaver in GNOME 3.2'.

Answer 5

You might find that the above solution is necessary, but not sufficient. The screen might still be blanking after 10 minutes. This is a default setting compiled into Xorg.

To disabled it for the current session, run:

xset s off

You can put this in your .xsession file to disable it upon every login.
