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?

I doubt this is your issue, but just in case...
Does it only fail to do the "Off" part or is it not doing any of the three?
I got tired of cats and random vibrations waking my monitor up, so I added the below to my startup programs:
cat xscreensaver-mouse-disble.pl
#!/usr/bin/perl # # This watches for transitions of `xscreen saver` and disables the mouse when it turns on # and enables the mouse when it wakes up. This stops the mouse from waking the monitor. # my $blanked = 0; open (IN, "xscreensaver-command -watch |"); while (<IN>) { if (m/^(BLANK|LOCK)/) { if (!$blanked) { system "xinput --set-prop 8 'Device Enabled' '0'"; $blanked = 1; } } elsif (m/^UNBLANK/) { system "xinput --set-prop 8 'Device Enabled' '1'"; $blanked = 0; } }

It wasn't doing anything at all.
The funny thing though, after I did this poking around, such as running "xset dpms…" etc, an hour later I came back and the monitor was powered down. Since then, all DPMS functionality was, once again, operating normally.
Originally even a reboot made no difference – that is DPMS still wasn't working after a reboot. But, manual poking with xset seems to have kicked something back into gear.

Ok, this problem kept popping up occasionally, and I've been able to do some additional digging.
It appears that after a reboot, DPMS is off. After a reboot, "xset dpms q" shows:
DPMS (Energy Star): Standby: 360 Suspend: 0 Off: 420 DPMS is Disabled
And after I issue a manual "xset dpms force off", then bring the display back up:
DPMS (Energy Star): Standby: 360 Suspend: 0 Off: 420 DPMS is Enabled Monitor is On
So, the issue is that after a reboot, DPMS is off by default.
