Hi. On Monday, upgraded from Cinnamon 1.8.x to 2.0.x and noticed that Cinnamon Screensaver no longer turns the monitors off when idle.
xset shows DPMS is definitely enabled and "Screensaver & Lock Settings" panel is still set to turn the screen off when inactive for 30 minutes (indeed, the screen saver *does* get invoked after 30 minutes of inactivity. it's just that the monitor's backlight is never turned off, not even when left idle overnight).
Any ideas where to poke to fix this?
