How to stop Gnome 3.4 from DPMS screen blanking

[maxibuntu]

In Gnome 3.4, by default, the screen blanks every 10 minutes or so. Maybe the Gnome developers think this is funny when you are watching a movie, but I sure don't.

I do not have the issue in XFCE.

All the following commands can be run from a Terminal, like for instance gnome-terminal. You can easily select and copy a command from this page, then paste it in a terminal, and hit enter.

I have a sudo setup on LMDE, if you have an su setup like on standard Debian, use:

Code: Select all

su -

...and enter the root password, and commands.

But we will continue with the sudo version:

To stop the screen from blanking you have to pass some configuration parameters to the X server.

In a terminal, run:

Code: Select all

sudo mkdir -pv /etc/X11/xorg.conf.d

Then create a new config file:

Code: Select all

sudo gedit /etc/X11/xorg.conf.d/01-disable-screen-blanking.conf

Copy/paste the following code and save the file:

Code: Select all

Section "ServerFlags"

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

EndSection

Close your applications and restart the X server with Ctrl+Alt+Backspace, or simply log out nad log back in again.

Check if it's in the repos first

Thanx, I didn't try this extension yet, but I think it only stops the screensaver via dbus. I don't know if it stops DPMS blanking. I'll check it out...

But you should be able to change this to at least 1hr?

No, I tried that. Those are the settings for the screensaver. It has nothing to do with setting DPMS.

Well I don't know, but in my case (I am using Gnome shell 3.4) Ijust changed the settings in system settings / screen brightness and block, and I have my monitor on for an hour when I am using my laptop to watch a movie. Anyway, thanks for your how-to

I wanted to test if the caffeine extension would disable the screen blanking on its own. So first I tried to get back the original screen blanking behaviour. I removed the config file in /etc/X11/xorg.conf, removed the caffeine extension, installed gnome-power-manager, set sleep time to five minutes in power management, set the screensaver to one minute, and absolutely nothing happens! I can't get the DPMS screen back! Gnome 3 seems to have really messy power management. Ah well, I'll stick with the Xorg config and deinstall the caffeine extension. As long as I can watch movies without interruption...

Yes, SOLVED

Thanks! I should keep notes about where my notes are.
So far, this works in any xorg whither Debian, Arch, Linux, Slacks, BSDs etc (sorry, not Mi¢ro$o£t Wind%w¢)
Seeing this, I remembered doing this same FIX in Debian and ArchBang once. As now the screen is still on after 30mins so far and going (instead of 10). This old box is on AntiX. It's the only thing that can access "random hdd" that I add as slave drives in. I'm installing/reinstalling hoping OSs as a hooby on old machines just to see how far it goes. I don't even network them into each other. I care even less for gaming. And I like having something that runs when I'm stuck in the mud with the next one ahahah;) (and at 25$ a piece these oldies, it's a lot cheaper than any twin or quad-display video card)

This time I have been looking for a fix through tty's :; --> I don't see why I should have at some level up, something or codes that works to put wherever, when I have to at the user level to put a code that will counter-act that un-needed output.

Yup. That worked for me. Thanks.
