Screen blank on idle

Postby virtualmix on Mon Oct 11, 2010 8:29 am

Dear LMDE people!

If I don't move the mouse or press a key, my display get blank after a few minutes.
I have deactivated all options in Gnome Screen Saver and Power Management preferences but it's not making any differences, my screen still blank on idle.

Any suggestion welcome.

Thank you.

Try disabling DPMS in your xorg.conf

Section "Device"
Option "DPMS" "FALSE"
EndSection

You can also use xset to disable it until you reboot.

Code: Select all
bash$ xset -dpms            # Disable DPMS
bash$ xset +dpms            # Enable DPMS
bash$ xset s off            # Disable screen blanking
bash$ xset s 150            # Blank the screen after 150 seconds
bash$ xset dpms 300 600 900        # Set standby, suspend, & off times (in seconds)
bash$ xset dpms force standby        # Immediately go into standby mode
bash$ xset dpms force suspend        # Immediately go into suspend mode
bash$ xset dpms force off        # Immediately turn off the monitor
bash$ xset -q                # Query current settings

Thanks a lot for your answer.

DPMS was activated in my xorg.conf so disabling it should solve my problem.

I'm discovering xset at the same time... Very useful.

Thanks again for your help.
See ya!

I tried your suggestion:

Try disabling DPMS in your xorg.conf

Section "Device"
Option "DPMS" "FALSE"
EndSection

The result was that my machine will no longer boot!

I had this problem on two laptops. I simply added a Control Center > Startup Application entry containing the command "xset s off" I called "Prevent Screen Blanking". It's run every time I log in and keeps the screen on.
