At some point recently, my monitor stopped getting turned off after the
prescribed period of inactivity. I'm using the XFCE power manager, and its
settings remain untouched.
Manually executing "xset dpms force off" turns the monitor off normally.
"xset q" shows that everything appears to be in order:
DPMS (Energy Star):
Standby: 300 Suspend: 360 Off: 420
DPMS is Enabled
Monitor is On
So, what else can I check?
