Linux – How to prevent Ubuntu from putting the monitor to sleep

displaylinuxSecuritysleepUbuntu

Ubuntu 10.04

Under Preferences > Power Management I have changed the settings to never put the computer to sleep and never to put the display to sleep.

My display still goes to sleep and I am prompted for my password when I leave the computer unattended.

I would like to be able to hit the "Lock Screen" app I added to the top panel to lock my screen, but otherwise I would like it to just stay on.

Thank you.

Check System>Preferences>Screensaver and see if "Activate screensaver when computer is idle" is checked.

Also, if you hit Alt + F2 and enter gconf-editor then navigate to /apps/gnome-power-manager/lock you can see if blank screen is checked.
