Description
In default gnome zen2 stage3 install, Gnome only partially controls DPMS settings. Xorg has defaults settings for Standby=600s, Suspend=600s and Off=600s. If one tries to set screen blanking via gnome settings to a value less than 600 seconds it will work, but if one tries to set blanking for > 600 seconds or Never, Xorg will override the settings in gnome.
