    Preventing screen blank on 12.04 + Cinnamon

    Hi,

    Can anyone tell me how to totally disable all monitor blanking and power-saving in Ubuntu 12.04?

    I'm using a fresh install of Ubuntu 12.04 with Cinnamon 1.4 as the basis for locked-down OPAC web terminals in a public library.

    The combination of 12.04 and Cinnamon is *spot on* apart from one problem.

    The screen blanks after a while, even though I've set the "turn screen off" option in gnome-control-center (System Settings) to "never". I've also tried setting gconf settings as per this post:

    Disable Screensaver (Black Screen) in Ubuntu 12.04 (Precise Pangolin)

    I've also trawled through dconf and gconf for Cinnamon-specific entries that might change power settings, but so far haven't found anything.

    I can verify that the settings persist after a reboot, that's fine. But the screens continue to go blank when not used. As these are always-on web kiosks, I'm really hoping to find a fix.

    Any ideas? Thanks in advance!
