I set a screensaver that freezes my computer and because changing the screensaver using the Gnome desktop displays the screensaver it locks up my computer before I can make the change.

I would prefer to set the screensaver off.

Using the graphical tool GConf Editor:

  1. Run the command gconf-editor from a terminal or the Alt+F2 dialog.

  2. Navigate to apps ➜ gnome-screensaver.

  3. Uncheck the idle_activation_enabled setting to stop the screensaver from activating automatically.

  4. If you want to set the screensaver theme to Blank screen, right click on the themes item and click Unset Key.

    enter image description here

From the command line:

  • Disable the screensaver from automatically running when the computer is idle:

    gconftool --set --type=bool /apps/gnome-screensaver/idle_activation_enabled False
  • Set the screensaver theme to Blank screen:

    gconftool --unset /apps/gnome-screensaver/themes
