Subject: [PATCH] Don't reset the lastDeviceEventTime when doing DPMS actions

When we change the DPMS mode, don't play games with the last event time as
this breaks applications using IDLETIME to turn the backlight off after a
preset time.

This patch fixes gnome-power-manager and xfce-power-manager
