12.04 how to (really) disable screensaver / screen blanker?

[bonuswhore]

I'm on Ubuntu 12.04 and I can't seem to be able to disble the screen blanker. After maybe 5 minutes of inactivity, the screen blanks out and goes to power saving mode. I run awesome window manager and it happens there but also in Gnome Classic mode. (haven't tried unity but I imagine its there too)

Things I've tried:

disabling in gnome-control-center: 'Don't Suspend', Turn off screen Never
gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false
gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0
gconftool-2 -s /apps/gnome-power-manager/timeout/sleep_display_ac --type=int 0
gnome-screensaver-command -d
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
gsettings set org.gnome.desktop.screensaver lock-enabled false
xset s off
xset s noblank
setterm -blank 0 -powerdown 0

I believe a work-around would be to install caffeine, but I'd rather find a solution without having to add third-party apt repos and install a daemon or whatever just to stop a screen blanker

Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"

added ^ to xorg.conf in ServerLayout and now I get no more screen blanking

Perfect, this appeared to resolve my issue. Thanks!

Will this work in Ubuntu 12.10 also. Am I correct that I should create a file /etc/X11/xorg.conf and populate the file with the following code:

Section "ServerFlags" Option "blanktime" "0" Option "standbytime" "0" Option "suspendtime" "0" Option "offtime" "0" EndSection
Just want to make sure I'm doing this correctly.

Many thanks.

There's a lot more on xorg.conf here, particularly in specific reference to doing exactly this:

Basically all these interfaces (unity, gnome, w/e) run atop basic xwindows. Sooner or later, you get down to x, and a lot of things can be set in xorg.conf as kind of a last resort. (This is how I got my multimonitor xinema setup working. Yes, it took that. But it works and is awesome.)

I think the fix is to go to 'Brightness and Lock' in the 'system settings' and put 'Turn screen off' to 'never' and then turn 'Lock' to 'OFF'.

This screen blanking Unix legacy has plagued me a lot over the years, so very happy to share it !

No need to go into BASH and do things to the OS.

Occam was right ! *LOL*
