http://ubuntuforums.org – I'm on Ubuntu 12.04 and I can't seem to be able to disble the screen blanker. After maybe 5 minutes of inactivity, the screen blanks out and goes to power saving mode. I run awesome window manager and it happens there but also in Gnome Classic mode. (haven't tried unity but I imagine its there too) Things I've tried: disabling in gnome-control-center: 'Don't Suspend', Turn off screen Never gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0 gconftool-2 -s /apps/gnome-power-manager/timeout/sl (Hardware)
